can I run 52v on a 48v BBS01B?

[manoz]

Hello all, I've been running a BBS02 750w with 52v batteries and was wondering if the I can use those batteries with a 48v 250w BBS01? I was considering buying a 36v BBS01 along with a 36v battery for another bike but realised they do a 48v BBS01 so want to use the same 52v batteries. Regards.

I don't know the answer for certain, but if you find it doesn't quite work (error 7 overvoltage, for instance), this thread

BBS01B 36V 250W - trying with higher voltage [success]

Hello everyone, I tried in a different forum, but did not receive any help, so I would like to ask you. Is it possible to make my motor BBS01B 36V 250W to work on 52V with standard controller (if not 52V, then 48V?)? I know about "error 07 - overvoltage protection", but everything else looks...

endless-sphere.com

has some info on getting around that.

Yes I saw that thread but figured 52v is closer to 48v than 36v but wanted to know for certain before purchasing

I have the bbs01b but I run it @66.6v with a 30A external controller. It does Climb anything, Top speed over 60km/h and does not get hot because I use a 36T chainring with 12 speed 52-11 Cassette. I did not implement PAS yet but I'm testing some solutions.

For Battery % I use Smart BMS app straight from the battery itself.
