Hi, I'm a newbie and I've recently purchased an Oxygen Lepton. My first order of business is to extend the range and upgrade to LiFePO4. Second order of business will be to make the scooter faster, but I will deal with that later. Right now I am asking everyones help to figure out the best combination of batteries for my application.
My needs: I need a 48V (do leptons react well to over-volting to 60v?) battery pack with at least 40-50Ah. The battery pack must also be easily removable (this shouldn't be a problem because of the location of the battery compartment on the letpton) so that I can take my battery into my apartment to charge it.
Restrictions: -Battery pack dimensions must be less than 19.5 cm wide X 17.5 cm tall X 65 cm long
-Scooter has regenerative braking (how does this affect the BMS?)
-Controller takes an input voltage of 48v and 70 Amps constant and 120 Amps peak
-Controller outputs 35V and 60Amps constant 100 Amps peak
-Weight must be less than 30kg
-Price must be less than $2000 with shipping, charger, and BMS. I would be willing to pay $2500 for higher Ah and/or proven quality. However, if the quality is dubious I would prefer to pay as little as possible.
I have minimal experience with electronics, so I would appreciate any help any of you can provide.
