Greetings.
I am wondering: as far as I understand, connecting an external battery will double the total charging time from 0 to 100. Obviously, its charging at the same speed, but there is just more battery to charge. As I understand, the charging current
is limited to protect the battery and thats cool, but if there is now another battery of the same size connected in parallel, both batteries will share the current equally. Seems reasonable that I could double the current from the charging port and each battery would be charging at normal speed.
I suppose naked batteries will take whatever I throw at them (and burn) and its the BMS that limits the current intake.
The charger is rated to output only 42v*1.7A=71.4w, so thats gonna need to change.
I suppose the real question is if the main board on the scooter is also limiting (or is physically limited to) the current.
