Cheap Bluetooth BMS
#31
@karrak at post 44 included a link to endless-sphere with pictures how to wire from 10 to 15S (BQ7694), is not enough to connect the fist x cables to work with it. So you must consult the seller if this 7S BMS have this feature and it is easily convertible from 4 to 7.

I have wired up this BMS through the balance lead connections - what gets wired up to C, P, & B terminals?

C = Charger
P = Load (not sure why this is not "L")
B = Battery

Make sure to pay attention to the symbol after those. If it's a + or a - makes a difference.
