Hello
I open the battery, how have 48v, now it's only 5v i'm thinking thé battery is empty
Inhve order à New charger

Image
I found 21v on three 48V packs, no way to charge correctly. But all 21700 cells
in good condition, around 3.8-4V.
Maybe one fuse blowed, direct cabling possible, but unsoldering needs massive power. (gaz flame)

Trois batteries 48V recyclées, charge impossible, BMS en panne. Cellules équilibrées à bonne tension.
Extraction du pack au cric hydraulique, mdr.
Cablage direct sur 1er contact, et pourquoi pas derrière le fusible. Soudures mastoc, obligé de sortir deux mini chalumeaux en synchro.


Salut

des news pour debloquer la batterie?

I do not recommend these models. I modified two of them and the handlebar has broken into 2 parts after some time and it cannot be used anymore. I don't know why it happens
