This happens to me only when connecting to EScribe, to reset I have to unplug my battery and balancing and reconnect and all is fine again and charges normally.

I do have USB-current and cellvoltages for all cells in display and why I noticed it.

Seems it happens randomly without any help of Escribe as well, it goes up to 0.7A then drops to 0.09 moments later and stays there, weird?

Does not happen always on my dedicated usb-charger but seems I can reproduce it every time I connect to EScribe, this is something that occured later hence I set usb-current and cellvoltages in display from day 1, it seems softwarerelated but I'm not really sure.

If the board temperature is over 130 degrees F or the air temperature is over 113 degrees it will throttle the charge current to 100 milliamps. 

Is this a 3d printed or plastic case by any chance?

Hrm, yeah that doesn't seem like it should be getting that warm unless the board is totally bedded in hot glue or something on the other side. The temperature sensor is down by the USB port, does that part of the board get perceptibly warm? 

We have some margin on the charger, so we could push the limit up a bit without it causing a problem.
