It would be challenging to build a 48V battery to fit this frame.Hello Rob,
Go for 43V or 48V battery.
Recently I saw Bafang started to ship 43V motors with reduced power to 10A. Dont know why. You can flash there then 43V and 13A firmware.
Or better to go for 48V and firmware v12.1 which is from April 2024. Can help you with this firmwares and settings.

4812E = 48V and 12A peak.
With DPC245 display (fw version 1.2) you will be able to connect to GO+ and set power levels. Unfortunately I have not seen yet on M820 possibility to set Assistance level %, like on M510 FC2.0.
