Arduino Micro based On-Bike Lithium Charger/BMS/AH meter

Mike.
I think your seeing a mechanical sliding contact, then a relay to latch onto the cell with the electronics?? and the hall sensor(s) tell the position of the rotor? Whey not just an array of reeds, two for each cell, break b4 make, magnet on rotor, positional control inside the servo? (mabye need an optical).

Ive seen a lot of reeds go for less than 10c per. thats $20 in reeds for a 100s setup or less mind you thats 200 reed switches. hmmm might be quite large eh? . of course this would limit balance charge current /bleed to around 1-2 amps. which would be enough?

intereseting. sorry for high jacking
 
I don't know how I missed this thread! Consider me subscribed. Seems like a project in the spirit of the "what electronics do we need" thread. An on board charger/bms/cycle analyst all in one would be a huge asset to the ev community. Thanks for posting Mike.
