Difference between SP140 v1.1

is there anyway to add the bluetooth to V1.0 units?

BMS would need to be swapped out, which can be done but take a bit skill and the BT BMS

I had the same question, for now I don’t want to mess up my battery that’s working fine so I’ll probably wait and purchase a second (Bluetooth) battery soon.

Ugh, I have already purchased 2 , one hour batteries. Dang
