1. Introduction
Lithium iron phosphate battery is one of new energy storage products developed and
produced by manufacture, it can be used to support reliable power for various types
of equipment and systems. DL-51200 is especially suitable for application scene of
high power, limited installation space, and restricted load-bearing and long cycle life.
DL-51200 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.
1.1 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 in on shelf; no
memory effect, excellent performance of shallow charge and discharge;
Working temperature range is from -10 ℃to 50 ℃, (Charging 0~50 ℃;
discharging -20~60℃) with excellent discharge performance and cycle life;
Small size and light weight, standard of embedded designed module is
comfortable for installation and maintenance;
