Firmware version 136 has been released.  There was a problem with the display updating on certain MK75's with the previous version 135.  This version 136 fixes that problem.  On affected devices instead of seeing the correct voltage it would show 0.00 Volts on the main screen.

This firmware version supports a new ADC type.  We had to change to a new ADC due to the chip shortage.  The new ADC is more accurate, although it does require that the shunt can only be wired into the negative terminal of the battery.

This version includes a fix for the charge efficiency not calculating correctly.  Charge efficiency is a measure of how efficient the discharge and charge cycle is.  It starts with a default value for each battery type and is gradually updated depending on battery performance.
