G30 Max stock BMS (48V upgrade)
Posted: Mon Jan 02, 2023 12:26 pm
Hey guys!
I'm asking for help with an additional battery pack. Recently, I created an external 12V battery pack (3S with a bit higher capacity than the stock 36V battery) from 18650 controlled by BMS (shorturl.at/fvzDU).
I've connected this battery pack into series with the stock battery and got approx 52V (fully charged).
Now, I have an issue. After a few meters, it just shut down with no warning or anything. I'm getting 40 at the freewheel with no error or shutdown. Shutdown occurs only when the scooter is loaded.
I've tried to exchange BMS for a battery pack but it has the same issue.
When is stock 36V battery connected, the scooter works as normal.
SW was flashed to one with a 48V battery mod.
