I have to change the battery of my xt1650-03, too. All sellers on a|_iexpress have negative comments from at least one or more buyers complaining that the battery is a few mm too thick. How can I find the right one?
This phone starts to annoy me so bad… it dies at 60 ish percent when drawing too much power…
* Why has the control unit 5 pins? It labels plus and minus for the 42V so far so good but what is the e.g. Vlm pin for?
* Also the charging cable has 5 pins. Why is that? The battery has 10 cells in series so I guess it cant be for balancing reasons.
* Where can I find such a connector/socket for the control unit plug?
The reason for my questions are that I am planning to do a 42V battery pack by myself.
