INTRODUCTION 

 
 
 
 
The batterX LFP3500 is a lithium iron phosphate battery in the form of a 3.5kWh module. This module acts as a 
reliable memory in a variety of applications. They contain their own integrated BMS, which monitors and 
manages battery voltages, currents and cell information. The BMS also constantly adjusts all cell voltages to 
each other, which further increases the service life of these modules. The LFP3500 is particularly suitable for 
applications with high performance, small installation space, limited load capacity and long service life. 
Multiple batteries can be connected in parallel to increase capacity and performance.  
 

 

 
 

CHARATERISTICS 

 
 

 

Cathode material is made of LiFePO4 with safety performance and long life. 

 

The  battery  management  system  (BMS)  has  protection  functions  such  as  overcharging,  overcurrent  and 
high/low temperature. 

 

The system can automatically manage the charge and discharge status, current and voltage of each cell. 

 

Flexible  configuration,  multiple  battery  modules  can  be  connected  in  parallel  to  increase  capacity  and 
performance. 

 

Adopted self-cooling mode quickly reduced the overall system noise. 

 

The module has a lower self-discharge, up to 6 months without charging, no memory effect, excellent low 
charge and low discharge performance. 

 

The operating temperature ranges from -5°C to 50°C, (charging 0~50°C; discharging -10~50°C) with excellent 
discharge performance and lifetime. 

 

Small  size  and  light  weight, standard 19-inch embedded  design module is convenient  for installation and 
maintenance.
