Jim,

The DualBatt Digiswitch usually does not discharge both packs evenly, they are almost always different, I say almost as Tuny's always does and I am using Emcotec's so do not know if it is like that to all Digiswitches. The Emcotec DualBatt does discharge the packs evenly, but that is just information as that is what I use now.

Regards.

Alejandro
