Title: Voltage levels at LVC
Post by: Lu.Sochr on August 20, 2012, 03:26:44 PM

Hi all,

I could not find any info about low voltage cut-off levels for GM battery packs and for magic controller.

Today for a first time I manage to run bike till cut-off occurred, but I was wondering if LVC was initiated by controller or by battery BMS.

Do anybody here know exact voltage levels for controller LVC and GM LiFePo packs BMS LVC? I am using 36V system and 15Ah GM LiFePo battery pack.

Thanks in advance for any info about this:-)

I don't know the exact numbers but....

If your power cuts out then turn your battery off and on again

If the power comes back on it was most likly the controller LVC that cut it out when you were hard throttling with a low battery.

If the power does not come on then it was most likely the battery bms that cut it out. The battery BMS will not power up the battery again until the instant you plug it in.

If you want to know the voltage even if the battery has cut out, you can measure it at the charging port.

Thanks very much for your reply Gary.

It seems it was controller's LVC, because I tried to switch it off and on again immediately after LVC (not ride it of course) and it turned on and voltage was slightly above 36V without load.
