I need some help identify the following PCB, I tried to search the numbers as seen in pictures, but couldn't find any related information.
This PCB is used on a battery pack for an E-bike.
The information I need regarding the PCB if it can handle adding more battery's to the pack, without extending the amount of current this PCB chagrining controller can handle.
Currently the pack contains 3 x 7 (Samsung ICR18650 26J 3,7V) that are connected in a series and parallel (7x3) for an output voltages of 24V and 7.8 Ah.
I was thinking of replacing these battery's and adding a total of 63 battery's of but keeping the same voltages of 24V, but that will increase the Ah (7x9).
Any help is appreciated
