Re: VOTOL EM-30S/Xiaoniu U1 Pro E-Scooter optimal controller settings/battery issue

Considering that my hardware specs for battery and engine won't change, what would be the best settings for the controller throttle/battery longevity wise? Engine: 800W Battery: 48V40.3AH (54.6V max. charging voltage, 39V min. charge voltage, 45 A max. discharging current, 12 A max. charging current...

Re: VOTOL EM-30S/Xiaoniu U1 Pro E-Scooter optimal controller settings/battery issue

you might, for curiosity, ask them why they want their packs to be fully discharged on a regular basis. my guess is they can't actually answer sensibly. Yeah, that is what I did, their explanation was that: "Battery cells are degrading over time, so you need fully discharge and charge again back to...

Man, really appreciated your time and reply (why I haven't found the forum earlier...)! I think what adds to the problem ...

Re: VOTOL EM-30S/Xiaoniu U1 Pro E-Scooter optimal controller settings/battery issue

it's not controller settings; if it worked before and you didn't change anything to cause it, then changing them now won't fix it. (though it may temporarily mask the actual cause, and potentially cause damage to the battery). the battery has a problem, most likely a bad cell or cells, or interconn...
