7S 24V BMS used for 24v 15ah 25ah 35ah  li-ion battery pack 3.7v cell 7S  PCM PCB BMS With balance function,temperature protection and on/off switch

Same port for charge and discharge, Discharge current is 35A

1. Overview

7S  24V 15A 25A 35A is used for 7 or 10series 48V Lithium battery pack.

We can design it for various lithium batteries like LiFepo4, LiMn2O4, and Li-polymer etc.

The main functions are: over charge protection, over discharge protection, over current protection, short-circuit protection, temperature protection etc.

 

2. Advantage

● Use top quality (A-level) protective integrated circuit IC, from the solution of Japan.
● Strong load ability, constant discharge current, use high voltage resistance, low inner
   resistance power Mosfet. The heat sink will greatly help cooling.
● IC itself has power balancing function. The circuit is simple and reliable.
● Typical voltage detection for each cell. So each battery will be prevented over charged or over discharged.
   Over current and short circuit protection function is very reliable.
   Long time short circuit of the load won’t affect the PCB and the battery.
   Temperature protection during charging and discharging.
Extreme low power consumption. The consumption of the whole device is less than 50uA.

● PCB use high anti-corrosion, high water resistance, high impedance ESD conformal Coating
