I just got a used EMax 110S. It may have a custom battery pack provided by previous owner, a distribution company.
After 45 km it died although 75% of the battery was left. I was able to restart after a few seconds pause and drive a few meters at low speed. Anyone knowledgeable, who can assist trouble shooting? Controller problem, dead cells in the battery, booster problem (after recharging, the problem returned after hitting the boost button - controller related or water in the wiring is my best guess)???

Considering adding lithium emergency battery with independent bms and adding relay to turn it on. Also considering adding functionality via app connected using bluetooth and supplemental controller.

Priority:

1) restoring eEscooter, incl battery
2) adding protection against water and more fancy integrated recharge

If money allows
3) adding bluetooth controller (speed limit/voltage profile)
4) adding emergency battery, if cells fail I would still be able to ride 10-20 km
5) improving appearance, I.e. dashboard, mobile integration...
