Vista Power EV-650A

[Roland G]

I cannot find any reference to confirm if cheali-charger can be flashed to vista power EV-650A, which is not too different from most b6 clones. It is a typical 4 button charger. Mine is still in daily use and I was hoping to change the firmware to enable charging HV lipo to 4.35V. I would appreciate someone pointing me to info if this has already been covered. Kind Regards,

Roland

Well... In those cases, you will need to open your charger. 

Very carefully, look for the microcontroller Brand... Usually the micro is behind the screen... So, try to figure out how to get the microcontroller specifications. 

Then, return to the cheali - charger library... And look for that microcontroller.

If you find the microcontroller, it is OK and follow instructions... 

If you don't find the one, stop...
