Introduction
Power Base X1 series lithium iron phosphate battery is one of new energy storage products
developed and produced by ZRGP, it can be used to support reliable power for various types of
equipment and systems. Power Base X1 series is especially suitable for application scene of high
power, limited installation space, and restricted load- bearing and long cycle life.
Power Base X1 series has built-in BMS battery management system, which can manage and
monitor cells information including voltage, current and temperature. What’s more, BMS can
help extending cycle life by balancing cells during charging and discharging.
Multiple batteries are allowed to be connected in parallel to expand capacity and power to
meet the requirements of longer power supporting duration and higher power consumption.

Lithium Iron Phosphate Battery
The lithium iron phosphate battery (LiFeP04 or LFP) is the safest of the mainstream lithium
battery types. A single LFP cell has a nominal voltage of 3.2 V. A 51.2 V LFP battery consists of
16 cells connected in series.
LFP is the chemistry of choice for very demanding applications. Some of its features are:
•
Durable and resistant - it can operate in deficit mode for long periods of time.
•
High cycle efficiency.
•
High energy density - more capacity with less weight and volume.
•
High charge and discharge currents - fast charging and discharge is possible.
•
Flexible charge voltages.

convenient to observe the system operation.
•
Battery management system (BMS) has protection functions against over-
discharge, overcharge, overcurrent and high / low temperature;
•
The system can automatically manage charge and discharge state and balance

13
current and voltage of each cell;
•
The adopted self-cooling mode significantly reduces noise of the entire system;
•
The module has less self-discharge, up to 6 months without charging, no memory effect,
excellent performance of shallow charge and discharge;
•
Working temperature range is from -20 *C to 55 °C: charging from 0 °C to 55 °C,
