Smart BMS with bluetooth

Smart BMS with bluetooth

Smart BMS with bluetooth is manufactured by LLT Power, a Chinese company - website: http://www.lithiumbatterypcb.com/

This BMS is the cheapest BMS with bluetooth available on online sites like Aliexpress as costs about 40€. The hardware seems very simple and that is an advantage for repair or mod/hack. Also should be possible to develop OpenSource firmware for it.
You can find on Aliexpress using this search keywords: “Smart Battery PCB board Bluetooth BMS”.
