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
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...
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
