Been there, done that. NEEEEEXT!!! Big Grin Big Grin Big Grin . I just want to get something that's been proven and someone has experienced the ups and downs. For example, I can vouch for this Chinese 7s BMS: :

But this 10s one sucks BIG TIME:
Always draining the batteries even though no balancing needed. Had it installed last night and today I see in anger how a cloudless day is passing by, I'm at work and the batteries not taking a single F*&%@ mW of power (from the remote monitoring.) BMS keeps on disconnecting the eSmart3 whenever it attempts to charge. modules were at nominal voltage when I left this morning (3.6 - 3.8v) Battery is now at 33.2v because of the draining.
