Rechargeable Lithium-ion Battery

Introduction
RT12100B-G31 is a lithium iron phosphate battery module. With a standard BCI
group size, it is designed to replace deep-cycle lead-acid batteries. The battery is
perfect for recreational vehicles (RV), marine (boats), trucks, cabins, and other
off-grid deep- cycle applications.
3
More than 4,500 cycles at a depth of discharge of 80%.
The product has the following advantages.
•Long Cycle Life
•High Reliability
•Low Self-discharge Loss
Supports both parallel connection and series connection.
The built-in advanced BMS manages charging and discharging status, helps in
balancing the individual cells, and ensures intelligent automatic protection against
over-voltage, under-voltage, over-current, high temperature, low temperature and
short circuit.
The battery can be stored for more than 6 months if it has been disconnected from
other devices.
•Flexible Connection in Parallel and Series
•High Energy Density
With the high energy density lithium cells, our battery is half the weight of the lead
acid battery of equivalent energy, and 70% the size of the regular lithium battery of
equivalent energy. It's easier to carry, faster to charge, and more convenient to use.
The built-in Bluetooth module allows real-time monitoring via mobile devices.
•Real-time Monitoring via APP

If the battery is placed on a moving object (eg. car), make sure the battery is
securely mounted.
•Cut off the power before wiring, installing or removing the battery.
•To prevent electric shock, please remove watches, bracelets, rings and other
conductive items (if any) and wear insulated gloves and protective goggles
before installation.
Pre-installation check.
The area where the battery is installed needs to be kept dry and stable, away
from water and fire sources, and the temperature and humidity of the area shall
be suitable for battery use.
Place the battery in the designated area.
Fix the battery modules tight.
Connect the cables.
When installing the battery, the tiny sparks generated during the connection do not harm
humans or damage the device.

Installation

• Before use, check if the voltage difference between the batteries is less than 0.1 VDC before using
them in series connection, or 0.5 VDC in parallel connection. If not, connect the batteries in parallel,
and float charge them for 24 hours after a full charge. Otherwise, over-current protection may be
triggered due to the large voltage difference.
• Do not mix batteries of different brands, types, models or life spans.
• In order to prolong the life span of the batteries, please make sure the length, diameter and internal
resistance of the power cables are the same when using multiple batteries.
Note
Connection Steps:
1. Connect the Positive Terminals of the batteries in sequence.
2. Connect the Negative Terminals of the batteries in sequence.
3. Finally, connect the Positive Terminal of the first battery and the Negative
Terminal of the last battery to the system.
Multiple Batteries
If you do not need to read the battery system information via APP, you can connect the
batteries in parallel as much as you want.
