Lithium ion will normally charge to 4.1 or 4.2 volts/cell and operate at 3.7 volts/cell. So if they are lithium ion I would think 10s would be logical.

It is supposed to be LiFePO4 and 12s. I guess I will have to open it up and count. I have been hesitant because of unfamiliarity. On a related point, can I mix chargers with batteries, or does LiFePO4 or Lithium ion each require a specific charger?

See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
