48v Battery with 60v e-motor.

Hello there! I have 48v40Ah battery and Votol EM50s controller. Recently I have got a new e-motor, but apparently it is labeled as 60v1500w. Would it still be possible to use with my 48v40Ah battery? If it is possible, what kind of downsides I may experience? Thank you everyone for your kind answers...

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 ba...

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

leaving the charger on will still fix an imbalance issue. the charger shuts off not because the pack has reached full voltage, but because current drops below a certain level... 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...
