Im using 52volt battery (14s 58.8v) so the controller you send me will not work plus i want something small and powerful . I was curious if BBSHD controller fits in the bbs02b placedustNbone wrote: ↑Apr 12, 2018 8:43 amI wouldn't recommend pushing more than 25A through the BBS02, and even at that you need to be careful about applying it at low RPM, there's gears and clutches inside that will not like being subjected to high torque levels.
After replacing my controller twice, I replaced it with a 25A Grinfineon.

It's sinewave, very quiet and smooth, reasonably good throttle control, and cheaper than the ESC you listed above. They also have a 35A version if you're looking for a bit more performance, that's probably about as far as I'd dare push a BBS02.
The BMS im waiting has a cut of at 60amps which it will be nice but i dont know if it will harm the BMS .fechter wrote: ↑Apr 12, 2018 8:52 amOne possible solution would be to use a CA3 to limit the current. The CA measures the battery current and controls the throttle signal to keep it below the programmed limit. With an ESC, it might be challenging to get all the CA parameters dialed in so it doesn't oscillate.
Any controller that is using a servo signal input has an inherent latency (delay) in the response that makes a feedback loop hard to control. With the PID loop in the CA, it should be possible if all the loop parameters are set properly, but this takes some trial and error.
No. BBSHD is slightly larger and won't fit.
I run a 16S LifePO4 pack and a 14S 18650 pack on mine, 60V is fine. The BBSHD controller won't fit on the BBS02.
