For the CANBUS battery that is indeed as far as I got; different communication as Yamaha, so the hack does not work. However, I do not know if you actually cannot simply recell without issues. Nobody here ever recelled a Giant powerpak CANBUS battery? I will ask at the suggested German forum as well (I even understand German ). I already found the UART battery should be no issue at all, BMS will accept everything, even 625Wh!

The battery BMS is of course linked to the other components of the bike (motor, display). Therefore changing the BMS seems not viable, as the bike will not recognise a custom BMS. (And the original BMS is fine, so why change it). I see a lot of refurbish companies offering to re-cell these batteries (although the CAN type not by all of them), so there should not be a major issue to do so. Just hoping that someone here knows whether these BMSs are ok with re-celling (with increased capacity of those).

I wondered whether it is possible to re-cell a Giant powerpak without running into issues with (blocking by) the original BMS. Both for the UART (5 pin charge) and the later CANBUS (3 pin) battery, as I own two bikes using those two battery types. Also, I hope someone here knows whether the BMS is somehow blocked (or not) to use cells with higher capacity than the original 300 Wh battery or that I can replace the Sanyo UR18650AA cells with LG M29 cells (praised for their performance at a lower price than Samsung/Sanyo). Is there any order of disconnecting the leads / balance wires that needs to be followed?
