BBS02 48v .. with 36v battery, possible?

Whitehawk · Jul 28, 2015

Hi all,

I have the bbs02 750w 48v, and a li-ion 36v15ah battery,

but the problem is .. minimum low voltage cut-off is 38v with the 8fun program,

So, do you know if there is a possibility to lower this cut-off under 38v ?

Best regards friends !

I believe the 500w/36v BBS02 is the dame motor with a different controller. So, if you replace your controller with the 36v version it should work with your battery.

Yes I know but I think there is a maybe a solution to down this cut-off low voltage..

Waiting for other suggestion

It's not possible and has been answered multiple times on the forum.
It has also been answered in the other thread where you asked the same question. Don't cross post please.

This might be a possible solution.

Trick the controller into thinking it has a 48v battery connected by adding a small 3S LiPo in series with the brown P+ wire going between the drive and the display. Perhaps a DC to DC converter could be used instead of the battery also. http://www.ebay.com.au/itm/New-600W...Step-up-Module-car-Power-Sup-OK-/261906509354

Never tried it and could possibly damage your controller but it might be a way around the low voltage cut-out issue.

Interesting, but that would mean the LVC is triggered by the display?

It would also mean the motor would spin at 75% of its normal 48V speed?

Can you not just reprogram the controller low voltage cutoff?

The minimum voltage setting you can program is 38V unfortunately.
