Thank you for your super fast reply!
I am sending this on to Nathan at FMA.
Perhaps they can get around this.
If not, I will just 'bite the bullet' and disconnect one battery.
I'd be very interested in what Nathan has to say about this issue. I spoke with him quite a bit late last year when they were doing the programming for the 10S. He told me at that time it would not be difficult to do, but didn't think there was enough room in the charger's chip to make the changes in programming.
I told him there would be a bunch of RC guys who'd be very appreciative of such a change, but when the charger came out it obviously does not have the capability. Since it is Internet upgradable, maybe they're working on something?
Oh for what it's worth, I never did have much luck getting ahold of Nathan via e-mail but he's not too tough to find if you call FMA....
