2. Introduction
Force-L2 lithium iron phosphate battery is one of new energy storage products developed and
produced by Pylontech, it can be used to support reliable power for various types of equipment
and systems. Force-L2 is especially suitable for application scene of high power, limited
installation space, restricted load-bearing and long cycle life.
Force-L2 has built-in BMS battery management system, which can manage and monitor cells
information including voltage, current and temperature. What’s more, BMS can balance cells
charging and discharging to extend cycle life.
Multiple batteries can connected in parallel to expand capacity and power in parallel for larger
capacity and longer power supporting duration requirements.
2.1 features:
➢The whole module is non-toxic, non-polluting and environmentally friendly;
➢Cathode material is made from LiFePO4 with safety performance and long cycle life;
➢Battery management system (BMS)has protection functions including over-discharge,
over-charge, over-current and high/low temperature;
➢The system can automatically manage charge and discharge state and balance current
and voltage of each cell;
➢Flexible configuration, multiple battery modules can be in parallel for expanding capacity
and power
➢Adopted self-cooling mode rapidly reduced system entire noise;
The module has less self-discharge, up to 6 months without charging it on shelf, no memory
effect, excellent performance of shallow charge and discharge;
➢Working temperature range is from -10℃to 50℃, (Charging 0~50℃; discharging -10~50℃)
with excellent discharge performance and cycle life;
➢Small size and light weight, stackable connection comfortable for installation and
maintenance;
