Thank you for choosing REMCO Lithium. Please take some time to read this User Guide to
ensure you understand how to safely connect and operate your REMCO Lithium Deep Cycle
battery. This guide covers the following battery models:
• RM12-75LFP
• RM12-100LFP
• RM12-130LFP
• RM12-200LFP
• RM12-120LFPSL
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. Any damage caused by disregarding these guidelines may void your
warranty.
These are general guidelines; please seek our advice or that of a qualified electrical
tradesperson if you are in doubt.
Lithium Iron Phosphate (LFP) is the safest form of lithium chemistry. However, a key
component of on-going safe battery operation is the integrated Battery Management
System (BMS).
2.1 Battery Management System (BMS)
The REMCO Lithium integrated BMS protects the battery from improper handling, monitors
and optimises performance to maximise lifetime and ensures safe operation based on a
wide range of internal and external conditions.
The integrated BMS provides protection from:
• Over / Under Voltage
• Overcurrent
• Short Circuit
• Over / Under temperature
• Cell Imbalance
A BMS is essential to avoid damaging the lithium batteries. When the system is not in use,
damage due to deep discharge can occur when small loads (such as alarm systems, relays,
standby current, etc) slowly discharge the battery.
Note: If you are unsure of a residual current draw, disconnect the battery using the battery
disconnect switch on your app or disconnect the positive terminal on the battery when the
system is not in use.

The Integrated Bluetooth App functionality provides easy access to monitor
and maintain your lithium battery to optimize performance and longevity.
Light Weight
Only 1/3 of the weight of traditional batteries.
3000+ recharge cycles (up to 5x more than AGM)
So much more cycle life than an equivalent AGM battery
Less maintenance and no sulfation
Does not require constant charging, unlike like traditional batteries.
Can be left in storage for a lot longer without deteriorating.
100%-amp hour capacity available
Traditional batteries should not be used past 50% of their amp hour rating and
cannot be used passed 70%. Lithium batteries can be drawn completely without
causing significant damage. Therefore, a 100AH lithium battery has the same
available power as a 200AH AGM battery.
Faster Recharge
Up to 50% faster than traditional batteries.

This battery contains lithium iron phosphate (LFP) cells. While LFP cells are the safest Lithium
chemistry, the stored chemical energy presents a risk of fire, burns or explosion if misused.
Avoid injury to yourself and others, adhere to the warnings in this guide.
• KEEP OUT OF REACH OF CHILDREN
• NOT SUITABLE FOR CRANKING OR STARTING APPLICATIONS
• AVOID SHORT CIRCUIT OF BATTERY TERMINALS
• DO NOT EXPOSE OR DISPOSE OF IN FIRE
• DO NOT OPEN THE CASE – WARRANTY IS VOID IF OPENED
• AVOID MECHANICAL SHOCK
• DO NOT DROP, IMPACT, PIERCE, OR DRILL INTO THE CASE
• DO NOT ALLOW WATER TO ENTER
• ALWAYS KEEP DRY AND CLEAN IF POSSIBLE
• NEVER EXPOSE TO DIRECT SUNLIGHT AND PROTECT FROM HEAT
• DO NOT CHARGE BATTERY BELOW 0OC
• DO NOT STORE BATTERY BELOW -20OC OR ABOVE 6OC
• ALWAYS HANDLE WITH CARE
3.1 Ensure the battery is physically secure
Although lithium batteries are light weight in comparison to lead acid, if not properly
secured, they can still become a dangerous projectile in a moving vehicle, RV, cart, or boat.
Ensure the battery is safely secured before travel. If in doubt seek our advice and consider
the use of mounting brackets to safely secure the battery.
3.2 Do not penetrate or open the battery case
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 the case in an
attempt to open it.
3.0 Safety

3.3 Maintain an acceptable temperature range
Like all batteries, lithium batteries operate and perform the best and last the longest, in
a cool and stable temperature environment between 10oC and 25oC. The window of
acceptable continuous operation is 0-45oC.
If you regularly operate outside of this suggested range, you should alter the battery
location or add better ventilation to preserve battery life. If the ambient temperature that the
battery operates in is greater than 65oC, cease use immediately. Operating outside of these
guidelines diminishes the life and performance of the battery and voids the warranty.
3.4 Avoid repeated shock and vibration
Whilst the battery is robustly constructed and protected in an ABS case, it is not designed
to operate continuously in high shock or high vibration environments. Use in normal 4WD /
RV environments is acceptable and the battery has been designed to perform within 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.
3.5 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.
Pay attention when using metallic tools in the vicinity of the terminals. Accidentally
contacting the positive and negative terminal with a metallic object will cause a short circuit
and spark. Always keep terminals covered when not in use.
3.6 Mounting orientation
Lithium batteries are “non-spillable” and can be mounted in multiple positions, upright or
on any of its sides. However, up-side down orientation (terminals facing the ground) is not
recommended.
3.7 End of Life Disposal
Batteries marked with the recycling symbol must be returned to recognized recycling
centres. After consultation, they can also be returned to the supplier. Lithium Batteries
are not allowed in household or industrial waste.
3.0 Safety 4.0 Installation & Usage
1. Ensure all batteries to be connected in parallel have been fully charged individually by
the same rated charger
2. Ensure the Open Circuit Voltage (OCV) of each battery is less than <0.2V of each other
3. Connect the batteries using cables of sufficient width to carry current required (6 gauge
<50A/10 gauge <100A) as per Figure 1
4. Ensure all connecting cable lengths are the same
5. Do not reverse connect the Positive and Negative
6. Ensure correct charge voltage and current is utilised for configuration (at least 0.2C
of total bank)
7. Complete a full charge once every 3 months of the system
8. Once connected in parallel, the batteries must be charged and discharged as a system.
Figure 1
Make sure the REMCO Lithium battery is not connected with the opposite polarity.
If the battery is not connected correctly, the BMS will be irreparably damaged and must
be replaced by a new BMS. This is not covered by the product warranty.
4.1 Pre-inspection
After receiving the battery, check if the case or terminals have been damaged in any way
(e.g., transportation). If they have, please do not place the battery into operation and contact
the retailer.
4.2 Connecting
REMCO Lithium batteries contain a positive and negative M8 terminal. Always connect
the positive terminal first, followed by the negative. Reverse the order when disconnecting.
Existing battery holders can be used if sizing is suitable. Make sure that the battery
is installed and fixed so that it cannot move back and forth during use. Tension the battery
strap.
4.3 Connecting more than one battery
The REMCO Lithium range can be used to connect to 4 batteries in parallel and up to
4 batteries in series. The batteries must be of the same model and capacity.

One of the advantages of lithium as opposed to lead-acid batteries, is longevity. To realise
the battery’s long life potential, consideration must be given to depth of discharge.
What is depth of discharge (DoD)?
Basically, how much battery capacity you have used before you recharge it. A deep cycle
battery lifespan is rated by the number of cycles (i.e. discharge then recharge = 1 cycle) it can
perform before the original capacity has reduced below 70%.
For example: REMCO Lithium batteries are rated to provide 2000 cycles at 100% DoD.
However, if you were to recharge after using 80% of the battery capacity instead of 100%,
they are rated to achieve 3000 cycles. That is an extra 1000 cycles due to better battery
charge maintenance.
The more frequently you recharge your battery, before capacity has been drained, the more
the cycles you will get from your battery, therefore the longer it will last.
The graph below illustrates the amount of cycles you can achieve by recharging more
frequently.
