(Not verified) 4-string 21700 lithium-ion battery protection board based on BM3451

Overview

The PCB shape is optimized, with slots and windows on both sides of the board, suitable for direct welding of 10mm nickel strip spot welding battery packs.

I'm not free recently, I'll verify again when I have time.

The board has not been verified , and the component parameters are for reference only!

Thank you, Bamboo.
Thank you so much.
Very urgent help, power supply people please help
