The bms is a bit iffy
Cant charge properly sometimes
And even though bats can go as low as 8-9 v bms cuts power ealry
I dont think it can do 40amps discharge
But as a kit its great verry nice and definitely usable

Excellent

Excellent! It worked without problems. However, for whoever is reading this, the BMS graph in the manual is inverted. If they connect it that way, it won’t work. I always recommend using a multimeter to locate the BMS, and it will work without issues. Recommended product.
