    Here is an updated basic schematic. There are Op-amps on the market that are rated for 36V continuous, that would be plenty for an 8S pack in case you want to future proof. As a BMS this is probably not the perfect...

    Correct as a battery monitor the circuit I provided would unbalance the pack. For the High accuracy resistance measurements it would be very good. Some of the uneven discharge could be adjusted by changing the resistor...

    No reason why this should not work. Just hook it up to an ADC and your done. This could be done with the test board I created since I set up the dividers to be changeable between different configurations. Just...

    Or 16bit single ended ADC with all channels scaled to 27-30V will give you sub mV readings. It really depends on cost. I have an 8 channel 16-18 bit 400kSPS ADC breakout for the ADS8698 series. Depending on what chip...

    1. No real practical way of doing this unless you went to invest in a large array of relays with an isolated supply to power the Teensy. 2. Unless you invest in high accuracy resistors your going to be stuck with...

    Been pretty quite the last few months on this, work has been keeping me extremely busy along with life in general. I significantly reworked the design a few weeks back and added Isolation between the analog and...
