i was thinking that for Regen to occur, then the voltage at the MCU has to be greater than the pack voltage, otherwise no current will flow back to the cells.i've ordered a couple of AD202 and will be able to take a better look at the mounting then. i would want to solder any wires at both ends and not rely on a sliding contact of a pin and socket--a sliding electrical contact is to be avoided whenever possible in my experience.The easiest way to raise the output to match the pack voltage, if that is what you want, then change the 6.8k on the control board to 6920 Ohm 1% or better resistor. This would bias the input higher such the the AD202 output would be read as equal to the pack.The gain setting adjustment on the AD202 would involve adding a precision 20k resistor between pins 3 and 4 in the SIP diagram of the datasheet, then a 100pF cap and a precision 1.180 Meg Ohm resistor between pins 3 and 2. A 1.2 Meg is a standard value but maybe the other can be found.
