2.0 Introduction
Congratulations! You have purchased a state-of-the-art lithium battery and we hope you enjoy many
years of trouble-free life. This User Guide describes how to connect and safely operate the Standard
Power (SP) range of 12V batteries. The term Standard Power refers to the internal BMS charge and
discharge current of 100A continuous. In contrast the LBS High Power (HP) range BMS can discharge
200A continuous current and can therefore be used in higher power applications.
This User Guide covers the following SP 12V battery range:
•LBS-12110-SP
•LBS-12110-SP-DCS
•LBS-12150C-SP
•LBS-12150C-SP-DCS
•LBS-12150C-SP-FT
•LBS-12150C-SP-FT-DCS
•LBS-12150-SP
•LBS-12150-SP-DCS
•LBS-12225-SP
•LBS-12225-SP-DCS
•LBS-12300-SP
•LBS-12300-SP-DCS
As with all batteries, you should consider the mechanical and environmental conditions that you
intend to operate the battery in to maximise overall performance and achieve the longest battery life.
LBS offer these general guidelines; however, you should seek LBS advice or that of a qualified electrical
tradesperson if you are in doubt.

3.0 Do’s and Don’ts
This battery contains lithium iron phosphate (LFP) cells. While LFP cells are the safest Li-Ion chemistry,
the stored chemical energy represents a risk of fire, burns or explosion if misused.
Avoid injury to yourself and others, adhere to the warnings in this Guide.
•Avoid mechanical shock
•Do not expose to fire
•Do not pierce battery
•Do not disassemble
•Do not drill into enclosure
•Do not short the terminals
•Do not allow water to enter
•Do not charge battery below 0oC
•Do not store battery below -20oC or above 60oC
To ensure a long and safe life from your battery, please ensure you consider the following:
2.1 Ensure the battery is physically secure
Even though lithium batteries are light weight in comparison to lead acid, they can still become a
dangerous projectile in a moving vehicle, RV, cart or boat if not secured. Ensure the battery is safely
secured before travel. If in doubt seek LBS advice and consider making use of LBS mounting brackets
to safely secure the battery.
2.2 Do not penetrate the battery enclosure
You may be tempted to drill into the aluminium enclosure to secure mounting brackets. Doing so may
inadvertently penetrate one of the cells which could cause thermal runaway and vapour emissions.
Do not under any circumstances drill or penetrate into the enclosure. Use only existing mounting holes
in the battery and short screw lengths no greater than 13mm.
We strongly recommend the LBS mounting kit with screws and brackets that are designed to safely
attach to the battery; alternatively use strapping and clamping to secure the battery in place.
2.3 Maintain an acceptable temperature range
Like all batteries, LBS batteries operate and perform the best, as well as last the longest, in a cool and
stable temperature environment of between 10oC and 25oC. The maximum window of acceptable
operation is 0-45oC.
If you regularly operate outside of this suggested range you should consider changing the battery
location or actively cool or heat the environment in order to preserve battery life. If the ambient
temperature that the battery operates in is greater than 60oC you should cease use immediately.
Operating outside of these guidelines diminishes the life and performance of the battery and voids
the warranty.

2.4 Avoid repeated shock and vibration
Whilst the battery is robustly constructed and protected in an aluminium enclosure, it is not designed
to operate continuously in high shock or high vibration environments. Normal use in a 4WD
environment is acceptable and the battery has been designed in accordance with these expected
conditions. However, dropping the battery or exposing the battery to a high number of excessive
vibrations may lead to a fault or failure of the battery.
2.5 Avoid exposure to water or salt spray
Whilst the battery is mechanically protected, the enclosure is only IP20 equivalent and is not designed
for a wet environment. Do not submerge the battery in water or expose the battery to direct water
spray. If it is likely that a water will be on the floor where the battery is located, ensure the battery is
facing upwards with the terminals (and electronics) on the top, so that any water that gets into the
bottom can drain out again without touching the electronics.
Avoid exposing the battery to salty water spray such as in a marine environment to avoid corrosion.
Salt laden air may also cause corrosion in the long term; therefore, minimise exposure by installing
the battery in a protected hatch or compartment.
2.6 Do not short circuit the battery
Whilst the BMS will protect the internal cells from short circuit, it is highly recommended to avoid
short circuiting the battery. The MEGA Fuse on the external positive terminal of the battery also
provides over-current protection; if voltage is not present on the +Fused terminal, check for voltage
on the +Unfused terminal to check if the fuse has blown.
Pay attention when using metallic tools in the vicinity of the terminals, as accidentally contacting the
positive and negative terminal with a metallic object like a spanner will cause a short circuit and spark.
Always keep the plastic caps screwed on when not using the terminals.
Always perform work on passive wiring first and connect the live battery as the last connection. If you
have to work on live circuits exercise due care and use insulated tools where possible. If you are unsure
how to install the battery, seek advice from LBS or a suitably qualified electrical tradesperson.
2.7 Mounting orientation
The typical operating orientation is with the terminals facing upwards (except the 150C-SP-FT) and
should be the first option if possible. Having the battery terminals facing forwards is also an acceptable
orientation. The battery uses the aluminium lid as a heat sink, the function of which can be hampered
by an upside-down orientation; therefore, mounting upside down is not recommended. If in doubt
contact LBS or a suitable tradesperson for advice.

4.0 Longevity & Depth of Discharge
One of the advantages of lithium batteries over lead-acid batteries is longevity. If you want to realise
the long life potential out of your lithium battery then consideration must be given to depth of
discharge.
A battery lifespan is rated by the number of cycles before the original capacity has reduced by a certain
amount; a cycle is defined as discharging from fully charged, to a percentage Depth of Discharge
(DOD), and then charging back to full again. So, DOD describes what percentage of the battery capacity
is being used each time.
Note: DOD is different to State of Charge (SOC, also known as Charge Level); in fact, they add together
to 100%. So, 80% DOD equates to 20% SOC.
The less DOD you use each cycle, the longer the battery will last.
This fact should be considered when choosing the battery Amp hour capacity. You will have a higher
return on battery investment if there is enough capacity at hand such that you are not heavily
discharging the battery on every cycle. Extra capacity ensures lower DOD, extended life and a higher
financial return on your investment.
LBS SP batteries have a cycle life of 5,000 at 50% and 2,000 at 80% DOD.

5.0 Battery Management System
Your battery comes with a Battery Management System (BMS) mounted internally.
The BMS is an electronic solid-state circuit board which manages the cells and protects the battery
across a range of scenarios which primarily includes over charge and over discharge protection. Unlike
lead acid batteries, over charging or over discharging a lithium battery may lead to a hazardous
scenario. Therefore, the BMS is the heart and soul of a lithium battery.
The Standard Power (SP) family BMS is a highly reliable solid-state device which is primarily designed
to keep the cells safe and the overall pack from being damaged by excessive voltage or excessive
discharge event.
The LBS High Power (HP) family has a BMS with sophisticated diagnostics and if that is a requirement
of your design then contact LBS about their HP battery products.

6.0 Installation
5.1 Non-DCS Model
The non-DCS model SP battery does not include an internal DC-DC charger. As illustrated in Figure 2,
it can be charged via the red positive (+ Fused) and black negative (-) terminals from an:
-External AC charger source;
-External solar charger source; or
-External DC-DC charger source.
Figure 2 –Battery Charging Terminal Connections
The procedure of installing the SP battery (with no internal DC-DC charger) is as follows:
1) Before making any electrical connections to or from the battery, first secure the battery in
place, preferably with the fit for purpose LBS mounting bracket kit, or using suitable straps.
2) Once the battery is securely in place, unscrew the plastic terminal caps from the fused red
positive (+ Fused) and black negative (-) terminals.
a. Do not lose or discard the plastic terminal caps as they are required at the end of
installation.
b. With exposed positive (+ Fused) and negative (-) terminals the battery is susceptible
to short circuit if a metallic object such as a spanner or wrench accidentally dropped
onto both terminals at the same time, causing sparks and potential damage to the
battery.
3) Using a spanner or adjustable wrench, remove the metal nut and flat washer on each terminal.
The nut will be re-used to ensure a tight connection following connection of the charging
source and loads. Do not remove the MEGA fuse between the two +terminals.
4) Ensure the charging source positive (+) and negative (-) has M8 ring terminals suitable sized
to match the battery M8 terminals.
5) Connect all the charging and load cables to the battery fused positive (+ Fused) terminal.
Place the flat washer on top and then fasten the nut tight (or max 8Nm if you have a torque

wrench). Do not use excessive torque and overtighten. Finally screw on the red terminal cap
or rubber cover to prevent short circuit and to ensure the securing nut remains tight.
6) Note, do not attach any loads or charging sources to the unfused positive (+ Unfused).
Doing so would render the fuse ineffective and may overload the battery, tripping internal
protection which would require return to LBS.
7) Second, connect the charging and load negative cables to the battery negative (-) terminal.
Place the flat washer on-top and then fasten the nut tight (or max 8Nm if you have a torque
wrench). Finally screw on the black terminal cap or rubber cover to prevent short circuit and
to ensure the securing nut remains tight.
5.2 DCS Model
The DCS model SP battery is exactly the same, however it includes an internal DC-DC charger meaning
it can be connected directly to a vehicle alternator / start battery via the DC-DC positive (+) and
negative (-) terminals only as illustrated in Figure 3.
Figure 3 –DC-DC Charging Terminal Connections
The internal DC-DC charger contains a status LED light and Voltage Sensing Relay (VSR) adjustment
trim pot, which indicates and adjusts at what input voltage (from the vehicle alternator / start battery)
the DC-DC charger turns on and off. There is a dead-band of 0.5V, so that it typically turns on at 13.3V
and turns off at 12.8V.
Note that the voltage sensed by the DC-DC charger when it is charging, will be slightly different to the
voltage measured at the vehicle alternator / start battery. This is because of the voltage drop along
the cable from the alternator / start battery to the LBS battery. If this voltage drop is too high, a thicker
and/or shorter cable may be required.
Connect the alternator or start battery positive (+) first and negative (-) cables second to the M6
positive and negative on the DC-DC terminals.
1. Once the vehicle engine is started, the green LED status light should illuminate if the battery
is charging. If the battery is not charging, check the:
a. Cable size which may be too small with excessive voltage drop; and
b. Voltage across the DC-DC terminals.
2. The DC-DC charger typically begins charging at 13.3V, and then the green light turns on.

3. If you need to adjust the VSR setting, you will need a small Phillips screwdriver to adjust the
trim pot adjacent to the LED light.
4. Remove the clear plastic sticker before adjusting, and remember to put it back it afterwards!
5. Turning the trim pot in a clockwise direction reduces the voltage setting and turning it in an
anti-clockwise increases the voltage setting. Use the LED status light to determine the correct
setting.
6. If the trim pot voltage is too high the charger never turns on. However, if it is too low it could
stay on too long and drain the start battery.
7. Once the trim pot is set it should never require adjusting again.
Other features of the DC-DC charger include three (3) switches:
Current Selection Switch
This switch allows you to select the amp charge rate from 10A to 20A.
Most vehicle cigarette sockets on the dashboard are rated for 10A only. So, if you are using the 10A
vehicle cigarette socket to charge the lithium battery then select the 10A on the rocker switch.
If your vehicle is fitted with a 20A connection, or you are connecting directly to the start battery, then
you can select the 20A charge setting on the battery.
Beware: If you select 20A when connected via a standard cigarette socket, you may blow the fuse
connected to that circuit in your vehicle.
Direction Switch
This switch provides the ability to reverse the DC charge direction (Out) so that the lithium battery can
be used to charge a flat vehicle start battery. The normal charge direction (In) uses the vehicle
alternator to charge the lithium battery via the start battery.
Note –this feature is not intended to ‘jump start’ the starter battery. It is a controlled charge (at the
selected current based on the switch, 10A or 20A). So, you might need to wait for 30-60 minutes
before the start battery is sufficiently charged to crank the vehicle engine, depending on how flat the
start battery is.
External Shunt Switch
An external shunt can be applied across the two (2) black negative terminals to measure current in
and out of the battery for accurate state of charge measurement, including charge current from the
built-in DC-DC charger.
If an external shunt is applied, select Yes.
If there is no external shunt applied (which is the default case) select No. This connects the 2 black
negative terminals together internally.

7.0 User Guide
Once the battery is securely installed and electrically connected it will automatically be available for
use. The internal BMS will actively ensure the battery is protected and operating safely at all times.
The battery requires no user interface or intervention under normal conditions.
The SP models come with a digital colour LED voltmeter which measures the battery voltage in real
time and can be used as an indication of battery state of charge. The voltmeter can be turned on and
off via the red rocker switch.
Please note, unlike lead acid batteries, lithium batteries hold their voltage over the cycle, dropping off
only when the battery is ~90% discharged, as indicated below for illustrative purposes.
Pay attention to this when assessing how full the battery is. Once the voltage starts to approach 12V
it is nearing empty and should be charged. Some helpful hints:
1. A normal full battery open circuit voltage (Voc) with no load rests at 13.3V to 13.4V;
2. Depending on the load it may dip 0.5V below the Voc;
3. Below 12V the battery is close to empty and should be charged; and
4. Low Voltage Disconnect (LVD) is set at ~10.5V.

9.0 Care and Maintenance
Like any battery, the environmental conditions impact the health and longevity. Therefore, consider
the following with respect to proper care and maintenance of your lithium battery:
1. If not intending to use the battery for a prolonged period of time (one week or longer), turn
off the voltmeter by selecting ‘Meter Off’ on the red rocker switch. This will ensure the
voltmeter is isolated and not drawing a small current. If the voltmeter was left on, then over
weeks and months it would drain the battery and ultimately flatten it.
2. If the battery is unintentionally discharged flat then it can be recovered. First remove all loads
sources and switch off the LED voltmeter. Apply a ‘dumb’ charger which charges the battery
without needing to ‘see’ the battery first.
3. For long battery life, keep it charged at above 13V at all times. Check the battery once a
month. If the open circuit voltage has dropped to 13V or below, then give it a boost. Ensure
the voltmeter is turned off at the red rocker switch.
4. All batteries, whether they are lead acid or lithium degrade faster in extreme cold and extreme
hot environments.
a. Do not charge battery when the ambient temperature is less than zero or above 45oC.
b. Do not operate the battery in environments are -20oC or above 60oC. Doing so would
reduce its life expectancy.

10.0 FAQ
Will the battery be damaged if allowed to fully discharge?
Firstly, the BMS has a low voltage disconnect at around 10.5V, so the battery will never discharge to
zero volts. If the battery is flattened and cuts out at LVD at 10.5V then it can be recovered without
damage if on occasion. If it is done repeatedly then it will have a negative impact on longevity.
Maintaining the battery charge at 13V or higher will maintain good battery life.
Look after your lithium battery and it will give you many years of service.
Can the battery be recovered from flat?
Yes. See Section 8.
Does the battery capacity degrade over time?
Yes, all batteries degrade slowly over time, even with no load sources connected. Storage temperature
is important to degradation. Roughly every 10oC above ambient 20oC doubles the degradation rate.
Cool ambient conditions are better as it slows down degradation rate.
