The Ebike i currently own:
https://www.voltbike.com/voltbike-nitro.html
Its a 750w 48v 17.5ah 80lbs ebike
My Situation:
I avg 40-50km range with it since i mainly use the throttle and rarely pedal. This would be fine if it didnt take 4 hours to charge 0-100%. I know i could probably charge it at 480w without stressing the battery that much however...
My Solution?:
I plan to build a 48v 30ah using 90 (3.2v 5000mah) cells in a 15s 6p configuration.This custom battery will have almost twice the capacity, twice the amount of charge cycles, a safer chemistry, 2-1 hour charge time (but i would need to have enough nickel between series connections to handle the amps), and it will be around 30-40Ibs.
Im fine having it be a big battery since i plan to upgrade my ebike to 1500w and uprade my battery to a 16s and replace the bms with a higher amp smart bms.

My Problem:
I know that i want to charge at about 720w since that gives me a little over a 2 hour charge time and my bms has a charge current limit of 15a so it would be perfect. Sadly this is where my completely theoretical knowledge ends, I don't know all that much about making a homemade charger and I would very much appreciate any and all help/criticisms.
