Dave,

Each turbo reg has two charging jacks. If you tap in to these jacks, it will give you the voltage PRE-regulator. I hook up two C-volts (no longer available) to see what the voltage of each pack is.

After switching to A123's I no longer use the turbo reg, as there is no need. The EQ-10 (and the other new Smart-Fly power systems) havea green light that indicates if the battery is hooked up, it will not however give you the voltage status. An on board volt meter, or checking with an external one, will be the best way to TRULY know. Even then, this will be while the battery is not under any true load so take that in to account too.

It's not IF, it's WHEN []
