Why only a single Balancer-Charger for LiPo batteries in your store?

The unit should be capable of a minimum of FOUR CELLS as a maximum, EIGHT CELLS would be good. - many D-I-Y projects use 19-24V packs.

It would be a good project for your range of components, too. Only the PCB would be required as a new item.

Just use a BMS (equalizer) and any cheap CC-CV power supply module... you get a perfect lithium charger for few $. there is beautiful & cheap CCCV power supply with digital display...
