result of incorrect or improper use or failure to adhere to the conditions in this manual.
WARNING
Failure to adhere to the instructions and conditions of this manual be result in
injury to persons or damage to your battery
Do not submerse battery under water (short water crossings under 30 secs
are acceptable)
Do not throw in fire
Keep away for high temperature sources and keep out of direct sunlight
whenever possible
Do not puncture, drop or cause impact to the battery at any time
These are deep cycle batteries for storage applications. They should not be
used as a dedicated cranking battery but can be used for jump starting if the
starter motor draw is within the peak current rating of the battery
Parallel or series installation is acceptable – see section of parallel & series
batteries
Never store at a flat battery without charging to 70% first. Keep voltages
above 12.5V (>20% state of charge during long term storage
Always use a LiFePO4 charger. Using the wrong charger will void your
warranty
Don’t short circuit or reverse the polarity
If you encounter any abnormalities during use, like very high temperatures,
leaks, smells or damage or distortion of the ABS case in any way, cease all
use and contact us for assistance
Never attempt to open the battery. This will void your warranty and expose
the user to injury from high current or electrolytes. Should you get
electrolyte in your eyes, flush with water and seek medical attention urgently
AllSpark batteries can power a 2000w inverter from a single battery. Do not
use larger inverters unless correctly matched with the right specification

2. Benefits of AllSpark Lithium Iron Phosphate Batteries
LiFePO4 batteries are far superior to lead acid batteries in every way:
1/4 of the weight of AGM batteries with the same usable capacity
Smaller physical dimensions (2/3 of the size)
Up to 2000-5000 cycles
Very low self-discharge – safely store for 12 months without charge
Sealed and maintenance free
Higher charge efficiency of 95% vs 70-80% for lead acid
Rapid charge rates - allowing for rapid charge rates up to 1C – fully charge a battery
in 1-3hrs
3. What size do I need?
If you have already purchased your battery, then you may well have already answered this
question, however if you haven’t here are a few important things to consider. Our
recommendation is to have 2 days power usage as storage capacity in your batteries. This
will provide you with a longer life for your battery and maintains higher overall battery voltage
levels, whilst giving you a buffer in the event of using more power on occasion or if you
aren’t able to charge at expected levels (i.e. poor solar conditions)
To calculate capacity:
If your regular usage is only for only 1-3 days (overnighters and long weekends) then back in
storage (and on charge) till the next use, then you can get away with a smaller battery bank.
Calculate your daily power consumption (total amp hours required per day), minus any solar
or DCDC charger input each day x 50%. If staying off-grid for extended durations, then a
minimum of 2 days power consumption divided by 0.8 x 2 to give you the minimum battery
capacity you should have.
To calculate maximum continuous current:
Capacity is measured in amp hours. A 100ah battery will last for 20 hours at a 5A current
draw for example. Maximum continuous current is calculated by adding together the current
draw of every device or appliance that may conceivably run at the same time. Add up all
loads that could operate simultaneously on 12v or 230v from an inverter. Running small 12v
devices will never be an issue all at the same time – i.e. fridges/freezers, lights, pumps,
travel ovens, fans etc however if you plan to run larger inverters for powering microwaves,
coffee machines, kettles, toaster, hairdryers or even air conditioning, then you will need a
battery (or multiple batteries) than each can sustain the continuous output current required of
the total load. Take a coffee pod machine at 1400w. When run through a pure sine wave
inverter it uses 10% more power in the conversion process and will draw 115-130 Amps
across a 12V to 13.5V range. All AllSpark LiFePO4 battery have a continuous output current
of 175 Amps (320A peak) with some models also having a 200A continuous output (and
500A peak). Each battery on its own can power a 2000w inverter. You can then parallel
batteries up to 600ah to provide longer run time. Contact us for assistance if you need help
with sizing or calculations.


4. Parallel & Series connection
All AllSpark batteries can be connected in parallel. Extensively tested and with thousands of
customers across Oz with parallel battery setups (including our own vehicles), this practice is
very safe and will not affect longevity of your batteries and is covered by your 4-year
warranty under the following conditions:
Parallel
1. Parallel connection is permitted up to 600ah on 12v battery banks
2. Parallel connection is only permitted with the same model of AllSpark battery. Amp
hour capacity and BMS specifications must be the same
3. Do not connect other LiFePO4 batteries in parallel as this will void your warranty.
The cells and BMS quality across other brands can vary greatly and poor-quality
components on other products or lack of protection mechanisms may damage your
battery
4. Age of the battery must also be the same – a few months between additions won’t
matter but adding additional batteries in parallel 12 months later is not an acceptable
practice. Contact us for further details should you need to do something like this
5. Charge each battery to 100% first and allow cells to balance for 24 hours before
connecting in parallel to other batteries. 1-2 batteries can be connected in parallel
by daisy chains from battery to battery. 3 or more should be connected using a
common busbar setup for both positive and negative connections with each cable
connection to the busbar of the same cable gauge and length to ensure equal charge
and discharge resistance. You can then connect you chargers and loads to the
busbar instead of directly to the battery terminals. This is also helpful when installing
shunt-based battery monitors.
6. We recommend using a minimum of a 2B&S gauge cable for parallel connections.
Series – rules for parallel connection also apply to series connection
1. Series connection is permitted up to 2 batteries to double the voltage. 12v to 24v if
using 12v batteries or 24V to 48V using 24V batteries. If you need larger storage
capacity, then consider using larger battery packs in the first place before series
connection to avoid series and also parallel connection in the same banks. Be very
careful when connecting in series to avoid short circuit events. Whilst the BMS has
short circuit protection to avoid damage to the BMS and cells, a short circuit event
may still cause extensive damage to the external terminals of the battery. This is not
covered under warranty.

5. Battery usage – Charge and Discharge
Discharging
Maximum life in terms of cycles and time will be obtained by keeping battery state of charge
above 50%, however all AllSpark batteries can be discharged to 100% (10.5V) without
damage to the cells or BMS. Regular deep discharge of the battery will “wear” the battery at
a faster rate, however you are also receiving more “used amp hours” at the same time and
therefore getting more use from the battery. A battery that is extensively cycled and reaches
the end of its usable life even within the warranty period is not covered by the warranty.
Warranty covers manufacturing defects in materials and labour and not wear to the battery
due to ongoing and extensive use.
The BMS has a limit on the amount of current it can provide on a continuous basis. Whilst
AllSpark battery BMS has a higher duty cycle compared to other LiFePO4 brands, they
aren’t magic and still have certain limitations. The minimum rating across the range is 175A
continuous output (with a 320A peak for 10 secs) in comparison to most other brands with a
100A continuous output (200A peak). All models can sustain a 2000w inverter from a single
battery. If you draw more than the rated continuous output, the battery may enter high
current protection mode and disconnect the operating loads. To reset, remove the offending
excess current and the battery will automatically reset.
Charging
A LiFePO4 battery needs similar charge voltages to AGM batteries for full cell charging,
however that is about the only thing that is similar and is where so many battery sellers that
claim you can use a lead acid charger go wrong and where so many unsuspecting
customers get caught out by these sub-standard el-cheapo batteries on the Australian
market.
Correct charging is critical to ensure maximum capacity is availability each usage cycle and
to maximise longevity of the battery. Lithium batteries require specialised charge profiles
and must not be charged using lead acid chargers, especially those with de-sulphation and
equalisation modes. This will cause significant charging issues (and ongoing activation of
high voltage protection modes in the BMS). These chargers can cause damage to the BMS
and cells if used and are not covered by warranty. The way that dedicated LiFePO4
chargers apply voltage and current is different to a lead acid charger.
A charger with a Constant Current/Constant Voltage LiFePO4 charge profile is required for
proper charging and increased longevity. To correctly charge your AllSpark LiFePO4 battery
to 100% state of charge please use the settings below.
Bulk voltage 14.4V - 14.6V
Float voltage 13.5V - 13.8V
Recommended charge current (per battery) 30 Amps*
Termination current (if applicable) shall be set at 3-5% of battery capacity
* Recommendation based on extensive age testing of cells. Best longevity and residual capacity obtained by controlling charge temperatures
through controlled charge current at 30 Amps.

Special Note for engine bay applications
AllSpark 100ah battery with 200A continuous output (500A peak – 5 secs) BMS is
designed for use in engine bay applications but must be treated correctly to maximise its
performance and longevity. Charge current must be of a range of 15-30A when installed
in engine bays. Rapid charge currents produce excess heat and when applied in addition
to already high ambient temperatures in engine bays, temperatures can exceed the high
temperature protection set points in the BMS. Internal cell temperatures (not ambient
temperatures) must be kept below 65 deg C to avoid activating high temperature
protection mechanisms. The use of this battery in engine bays is covered by warranty,
however users should be aware that high temperatures will wear battery cells at an
accelerated rate and as such is a trade-off of convenient installation location (i.e. not
taking up precious cargo space) vs higher cell/battery longevity in non-engine bay
installations. It is entirely possible that a battery in an engine bay may reach the end of its
useful life during the warranty period if sustained high temperatures are experienced
through towing or regular off road driving (especially in low range with limited airflow) or
just high heat location. Installation in battery trays adjacent to turbos or exhaust manifolds
should have a heat shield installed and the battery wrapped in an insulating air cell blanket
for improved temperature performance and increased longevity.

6. Charge sources – DCDC, Solar, Alternator &
Mains/Generators
If you need help selecting or matching a charger for your battery, please contact us for
recommendations on makes/models to correctly and safely charge your AllSpark LiFePO4
battery.
You may charge your battery using any or all of the following types of chargers. Each
charger must have a dedicated LiFePO4 profile and be of the correct nominal voltage.
AC mains to DC charger - using either mains power or generator power. Only use
generators with clean Pure sine wave output to avoid damage to sensitive electronics
in your AC to DC charger. Do not use the 12V output that many generators have.
They have limited current output and generally have very low voltage compared to
that needed for proper charging
DC to DC chargers – from alternator or solar inputs. Do not charge directly from the
alternator without using a DCDC charger as there is no control or regulation of
voltage or current directly from the alternator.
Solar charge controllers – never charge directly from the solar panel without a solar
controller
When using multiple charge sources, it is critical to ensure that the total charge current is
always controlled. You must ensure that your batteries are not being excessively charged.
A common scenario is having roof top solar on a caravan connected to a dedicated solar
charge controller, that is sized to provide the maximum recommended charge rate for the
battery/s, then the user hooks up a tow vehicle, thereby connecting the DCDC charger with
input from the alternator as well. It is possible to more than double the recommended
charge rate and must be considered when sizing your batteries, chargers and solar setup.
Contact us for assistance if required. We are more than happy to help.
AllSpark batteries have a recommended charge rate for each model. This recommended
charge rate is based on extensive age testing in laboratory conditions over tens of
thousands of cycles to provide you with the maximum longevity and output capacity.
All models have a rapid charge rate (or maximum charge rate) of 1C, but this must be used
only in emergency conditions and temperature must be monitored and controlled. Any
increase of internal cell temperature of 15 deg during charging will reduce the life of the
battery. Ongoing rapid charging above the recommended rate may lead to premature failure
of the battery and is not covered by warranty.

7. State of Charge
State of charge is somewhat difficult to determine on LiFePO4 batteries by voltage alone
due to the very stable and much higher operating voltage throughout much of the range of
use from 100% down to 20%. AllSpark batteries required 14.6V (3.65V per cell) for 100%
charge, though you will see a slight increase in overall cycle life if you limit charging to as
low as 13.9V (3.475V per cell). This is a user preference. Charging to 13.9V will obviously
give you a smaller capacity range to work with over about 90% less.
A fully charged battery will reach 14.6V at the end of the bulk and absorption charge stages
and be held at that voltage until the termination current is reached (usually between 3-5% or
battery capacity), then the charger will enter the float stage ranging from 13.5 - 13.8V for
most brands. Most chargers will not re-enter bulk charging again until the battery voltage
drops below 13.3V. A fully charged battery at rest (open circuit) will sit between 13.3 –
13.4V. During normal operation the battery state of charge from 100% to 50% will only move
a small amount of around 0.2 – 0.3V. As you can see, due to the very stable voltage curve,
it is hard to determine an accurate state of charge from voltage alone. As a general rule
(subject change due to very high current use from large power inverters) AllSpark batteries
will reach 20% state of charge at approx. 12.5V. This is the recommended minimum voltage
to maximise life of the battery. 0% will be reached at 10.5V. Low voltage protection mode is
activated at 10.0V and the BMS will disconnect all load output.
To accurately measure state of charge and allowing for regular monitoring of your battery
health we recommend using a quality battery monitor with a current shunt to measure
current (or amps) in and out of the battery. Please contact us for recommendations on
reliable and accurate brands.
We have started to introduce Bluetooth monitoring into our range for monitoring state of
charge from smart phones and tablets. This is available in our 100ah battery with 200A
continuous output (500A peak) and will be added to other models during 2020. Available for
Android and Apple devices early 2020.

8. BMS protection re-activation
If by chance you happen to use the full 100% capacity of the battery and allow the voltage to
drop to 10.0V (or any cell drops to 2.5V), then the low voltage protection mode will be
activated. This disconnects all loads and the battery will go open circuit with no voltage
output at the terminals. This is designed to protect the cells from damage in the event of
excess discharge either from lack of charging or if loads are accidently left on when not in
use.
A LED light left on for example may continue to run even at less than 6V and if the BMS did
not switch off, would cause irreparable damage to the cells. Other devices like external
battery monitors, DCDC chargers and solar controllers or vehicle management systems can
draw very small currents every hour (many in the 10-50mah range). In normal operation
your system won’t even measure this and is lost in the rounding, but when left connected
when in storage with no charge input, can drain a fully charged 100ah battery down to 0%
state of charge and activate the LV protection mode in around 4-8 weeks.
Once LV protection mode is activated, most chargers on the market (Solar, DC to DC and
some cheaper AC mains to DC chargers) will not be able to start recharging the battery until
the BMS is re-activated (woken up or brought out of protection mode). When in protection
mode, the battery will not provide any voltage and as such, most chargers won’t recognise
that a battery is connected, hence they cannot start the charge process until the BMS is re-
activated.
The process for reactivation of the BMS is quite straight forward:
Ensure your normal charging source is connected and ready to start charging once
the BMS is re-activated – this can be AC mains to DC, DC to DC or solar
Apply 10.0V or more and 1A or more to the terminals of the battery with an external
source – this can be done with a parallel battery, external power supply, jump starter
pack or an AC mains charger with the correct functionality to re-activate the LiFePO4
BMS (using one with a switch mode power supply)
As soon as the BMS is activated (only takes a couple of seconds), the normal
charger will read the battery and start the charging process.
If you have an AC mains charger with power supply mode, then simply turn on and
charging will commence
We have a number of charger options that do include this functionality to avoid the
challenges of waking up LiFePO4 batteries in protection. Contact us for assistance.

9. AllSpark LiFePO4 battery care
To get the best life out of your battery, you want to do a few key things to look after your
battery.
Read this manual in full before using or charging the battery
Keep your battery cool and dry and away from direct sunlight (which increases cell
temperatures unnecessarily
Check battery terminals are tight on a regular basis, especially if driving over lots of
corrugations and are free of any type of corrosion
Avoid water crossings where possible and keep the battery dry. Whilst the case is
sealed, they cannot sustain extended periods of submersion and as such water
ingress into the battery under pressure can occur. Water ingress is not covered
under warranty.
Don’t attempt to open the battery for any reason. This will void your warranty and
can cause damage to the BMS and cells. There are no user serviceable parts inside
Do not try to charge the battery using the BMS to PC communications port on the top
of some models. This is a diagnostic port for downloading BMS data only and can
only be accessed by AllSpark services technicians
High charge currents create large amounts of heat. Excessively charging your
battery may cause damage that is not covered under warranty. The BMS logs all
extreme events of temperature, current and voltage
Avoid short circuiting your battery or reverse polarity. Failure to do so may cause
damage not covered by warranty
Charge it correctly using a dedicated LiFePO4 charge profile
Don’t excessive discharge the battery every cycle. Try and keep it above 20% state
of charge
Don’t leave it in a discharged state in LV protection mode for more than 2 weeks
without charge
10. Storage
In storage keep cool and dry - ideally between 10-45 deg C
Avoid storing on concrete floors
If leaving in storage for long durations, disconnect the negative cable or install a
master isolation switch in the positive cable
You will get an increase in life expectancy by storing your AllSpark battery between
40 and 80% state of charge. If placing in storage, discharge the battery to 80%
before disconnecting all loads or use a mains charger that has a dedicated LiFePO4
storage mode. Contact us for recommendations
Check the open circuit voltage every 3-6 months and recharge back to 80% if
continuing in storage
