I don't think this statement is true:
"They also optionally send a signal back to a Manzanita Micro battery charger (or other charger) telling the charger to cut back its current because one or more batteries can't accept this level of charging current. "
I believe the reason the current needs to be reduced is to prevent damage to the *regulator*, not the batteries. The regulator dissipates the excess current as heat, and it can only dissipate so many watts before it burns up. The batteries, on the other hand, are sized to handle the large currents needed to move a heavy vehicle.
A rewrite would be something like this:
"They also optionally send a signal back to a Manzanita Micro battery charger (or other charger) telling the charger to cut back on the charging current because one or more regulators are getting too hot."
- I see it from the perspective that the regulator is running because one of the batteries is out of balance on the high side, so it need not be overcharged. Rich would have to weigh in with specs but I get the impression that his regulators have fairly respectable thermal dissipation abilities. I think technically the way it is now and your rewrite are both accurate. At the core of the feature of cell level regulation is that multiple battery cells tend to become unbalanced. Where some batteries can't accept some level of charge while others take more time to come into equilibrium. *shrugs* --Rjf 00:28, 24 September 2013 (CDT)
