| Product Feature and Application a. Battery management circuit board for 76.8V 24S LiFePO4 battery pack. b. BMS/PCB/PCM applies for 24 cells LiFePO4 battery pack. c. To prevent the battery packs from overcharge, over discharge, over current, over temperature, short circuit, passive balance to balancing each cell's voltage and current. d. With heat sink fully dissipates heat, keep the temperature at normal operating temperature, It also protects the parts from collisions, Dust and moisture proof to better protect the PCM and make life longer. e. The Max working current: 35A. f. Compatible with both LiFePO4 cells. (could be adjustable to Li-ion) f. It is suitable for the following products: Electric Vehicle battery packs, 10S- 24S battery pack, E-Scooter battery packs and any products. |
