Hi guys ! You may remember that we talked about battery management systems to be used with li ion batteries in a previous video. When creating a battery pack using lithium batteries, a suitable battery management system or a BMS module must be used. . So today we will talk about a BMS module which is operated by bm3451 single controlling ic in this video.
---Description---
1. This protection board is 3s 4s 5s in common use LiFePo battery protection board
2. specific chip, stable performance, support disconnect protection, over-current protection, over-current protection, overload protection, with balancing, etc.
3. Common use for "same port" and "different port", the protection board uses 15 ultra-low resistance high-power MOS tubes (discharge of 8, recharge of 7), in the same port mode can support the current of discharge 60A, recharge current 60A;
4. Can be used for LiFePo batteries, battery packs etc.
