IF you got tired of braking down original EMS chargers here is the one which works with our EPLUSes.

I have initial reservation but hooked up to hub battery and it looks like it charges, it is less complicated than EMS charger for sure
it uses rise in temperature over time to detect end of charge and 8-hours time out.
Anyway charger works
EMS batt electronics registered charge and displayed 5 bars.
