I acquired a few NOS MP2s earlier this year, and I've yet to run one of them myself. I installed one for a gentleman whose e-bike was stolen. He ran it at 36V and was raving about the regen braking. I just picked up a chopper (Nirve Cannibal) and I want to run one of the MP2s in front. I'll first weld a disc tab on the fork.
Anyway, I'm wondering if I can safely run this motor with a 52V battery. If fully charged, it would be at 58v. Is that too high for the stock controller on an MP2? I like the "cleanliness" and simplicity of the internal controller, so I'm hoping that I can keep it. Would it play nice with 52V? I just bought the 52 for my other bikes, and I'd live to use the same battery for all of them. Thank you for any thoughts and/or input you're able to offer.

That voltage will be fine for the MPII controller, I have been regularly running mine (modified for more current when it was fitted back in 2011) on both 7S and 14S LiPo (29.4~58.8V fully charged) without any problem.
And I really prefer the regen on the MPII to the later MP4 and MP5 motors! ;)

Excellent. Thank you for the info. I followed some of the info found in this forum and modified one of the MP2s, but I've yet to run it. For this build (an e-chopper), I'll probably just keep it stock as I've read that too much power on a front wheel can get dicey (especially on a chopper). I don't anticipate needing to accelerate quickly. I just want to cruise around on a cool bike from time to time. 8)
