This might be the wrong place to ask this, but what makes Bestech BMSs (or specifically these models) any better than the cheap ones you can get from China? Are these more reliable / charge more efficiently / balance more aggressively / or something? Not hating, just curious
I know no science behind my feelings, but using a recognised brand of BMS and to some extent certain models that have been tested gives me more confidence in my batteries.
With a lot of time, effort and money involved in putting the cells together I have always spent a few pence more.
What Ben said. Especially when using a discharge BMS in which case a failure can leave you without brakes.
Bestech discharge BMS are the only BMSs I know for sure and that only goes for certain models.
a) will not cutout when going down a step hill with a fully charged battery
b) will allow me to exceed the BMSs rated charging current when setting battery regen.
