It's true, Karl. I'd be better off with a sealed pack (or mostly sealed) even in dry weather.

I think team222badbrad was getting at a similar idea -- discharging in series, and then switching over to a parallel arrangement for one-tap charging.
If the four series "lobes" of the Segway power are discharged to the same level, I will look into doing that..

Charging as a 9S4P configuration, or even a 3S12P would be much easier to wire externally.

I checked the in-battery circuit board, and there are taps between each 12v module, and a whole lot of digital circuitry in there, so I don't think I can pull one over on the Segway by wiring more directly.

Still, ANY miles is better than zero miles and a BEEP BEEP BEEP "get off" going uphill.
