I've been trawling the internet for a passive battery balancing circuit and came across one I am happy with. See attached - not my circuit credit elsewhere. For my application I am installing the battery pack and balancing circuit together. I have run some simulations and it seems current is consumed at idle (legs with R1 & R3 etc).
The schematic image attached is my circuit. I am not sure if it is a valid n channel mosfet circuit (Q3 & Q6). While it does simulate ok in Multisim I do no trust it as it does not seem right!
The circuit works as follows:
regulated and controlled power comes in by H1 (CV & CC at 8.4V)
the circuit is divided into 2 cells
if the cell voltage is high power is shunted
when H1 is disconnected the passive balancing circuits are also disconnected.
