In other news, believe I've found the weakest component so far...looks like they are running battery voltage through an SMPS buck converter before sending it on to the rest of the system and the linear regulators. A 13S "48V" battery could be approaching 54V fully charged and that is just too much to slam into simple LVRs. The SMPS looks to be based on an MP2459 driver which has rated max voltage input of 55V and "absolute maximum" of 60V.

So if anyone is thinking of hotrodding the controller beyond a 14S pack, which might already put you a bit north of 58V fully charged, then it might be wise to do some surgery on the 2459 and provide a more robust way to get down to 'nominal' voltage levels.
Thank you, this explains their hard maximum on 58v in firmware. If you go over the board wont start.
Probably so. Though would be really nice if that could be 59V, or even the full 60V. That would allow for a fully charged 14S pack @ 58.8 ... and what's 0.8V among friends!??! :wink:
