usable volts

[40buickcoupe]

I have a 48 volt ebike and woundering what the low cut out is? I have a volt timer I want to set up so it buzzes before it comes anywhere close to cut off

Most are 39v LVC but you can get others that are 32-35 LVC.

I'd stick around 36-39v LVC

See chart here...

48 Volt Nominal Voltage Chart for Ebike Batteries

A 48v battery is fully charged at 54.6v. The low voltage cutoff is around 39v. It is best not to discharge more than 80% of the capacity for good cycle life. 80% DOD is around 43v depending on cell chemistry. Li-ion has a flat discharge curve. The voltage will drop from 54.6v down to 50v fairly...

My Juiced Scorpion X lets me set that low voltage threshold …..52 volt is set for 46 volts on mine.

what do you mean? I have high end set at 54.2 and cutoff at 39 and have my alarm set at 42 volts

my high end is 58.3 volts and since I have added a 2nd battery I don’t have to drain these batteries so low, and have chosen 46 for the low end.

where did the 58.3 volts come from?

i see it in your video my batteries are 54.6 volts

The used scorpion X screen displays the current voltage of which ever battery I’m using. I have a 15 amp hour standard and I’ve added a 20 amp hour aftermarket and both of them charge up to 58.3 V
