It's from Xinron New Energy Texhnology, they also have some very reasonably priced 16s 280-305 battery boxes, for like 240, free shipping, this is their bms that can go with it or you can use jbd bms, but this one huts every checkmark for me, active balancing (5a) , Touch screen lcd, 200a, and most importantly communicate with SRNE inverters, which the jbs doesn't.
