    The BMS board I received is a different design from the one in this product listing. I received model CF-B34S30A-A, which appears to have similar capabilities and is OK for my project. However the wiring layout is different, and is done like this: Battery pack negative lead goes to the large B- pad. Charger/Load negative lead goes to the large C- pad. Battery pack positive lead is connected to the charger/load positive connection, and does not connect to the BMS board. The balance connector is wired like this: the wires connect to the cells in order beginning with the black wire at battery pack negative, and ending with the last red wire at battery pack positive. (B-, B1, B2, B3, B+)

    Платы пришли аж в два пакета всё целое. Спаял батарею вставил в шуруповерт пуск - и сразу заработало. Пробовал и резко на кнопку нажимать и плавно - всегда запускалось хотя у человека в обзоре mysku.ru/blog/aliexpress/58000.html возникли проблемы. А у меня другая проблема: плата отрубает батарею при 2.8-2.9 В на акк хотя заявлено 2.55 В (если исчезли запятые - претензии к системе бангуда).

    Fiz testes rápidos de carga e descarga, excedi a tensão de carga e ele protegeu as baterias e a ele mesmo, fiz uma descarga de 55A e o sistema abriu a proteção, perfeito. Nao esquentou muito na carga, mas na descarga a 20A apresentou um aquecimento, nada fora do comum e que um dissipador pequeno não resolva. Provoquei um curto em um pak de 35A e ele isolou as baterias perfeitamente. RECOMENDO MUITO

    Пайка хорошая, флюс отмыт. Плату проверил, работает как положено. Самая лучшая цена.

    BMS is great ....high quality ...but very low packaging no bubble wrap nothing ...it would easily break with a shock it was packed directly into the packet
