E-bike Vision Classic 458

10S5P design, 13 Ah -> 458 Wh

11 T15 screws hold it together. No flaps. Strong plastics!

It has two charge ports - the second is a 4-pin XLR. Uses the same 5V enable.

Recovery from deep discharge

The BMS needs to be de-energised: remove B+ and the sense for a while, then reconnect, it should now accept charge! :)
