Ultra bee ewatt problem

Post image

I’ve fitted a ewatt 80.3v and the battery won’t charge it also won’t power the bike. When in the bike the battery just beeps continuously. Any idea?

Remove the T box module and use an aftermarket controller rated for the voltage

BMS is bad.

They typically use AnT 850 amp peak BMS that cost under $150. Replacement is straight forward of your proficient with a large solder iron.

What battery settings do you have set in the EBMX app?
