I just had my first ride today with this build.
I managed to squeeze around 4km with 10A 6S battery. I think half was uphill.
The battery died pretty quickly, even the meter shows half voltage the esc’s does not power the motors anymore. (I have another 4 x 8A 4s battery dispatched to make a 8S2P setup)
I went home to charge the battery with this charger. It took 17minutes for fast charging with 3-4A current, even the display shows 749mAh capacity charged. Isn’t this strange? Something must be wrong, is it way too fast.
