This is what I put, so if anyone else gets freezing issues like this, watch out ! :
"I purchased an Adaptto Max-E Controller in July, and it has been working fine for the last two weeks. Yesterday I decided to plug in the bms and use a HP ESP120 power supply to charge the batteries through the adaptto charging coil and bms.
Yesterday this worked fine and charged the batteries with no problem.
Today I turned on the charger and went into the next room, and when came back it was working just fine, I came back 5 minutes later and on the screen was displayed “BMS Error” .
The controller buttons now will not work, the throttle and ebrake also do nothing when pressed.
If I turn off the controller for 2 hours, then turn it back on again it will work for 1 minute and then freeze again.
I have tried updating the firmware when it is frozen and the controller does nothing, and is frozen on the firmware version page.
If I leave the controller turned off for two hours, and then try and downgrade / upgrade the firmware, it then says on the screen that the console firmware is upgraded ok, but when it starts to upgrade the controller firmware it gets to 25% and then freezes.
