Yeah, I agree. It's unlikely that they will operate well. I can think of a way to do it that MIGHT work, but probably too convoluted to be worth it, and it wouldn't be the best solution IMO.

6s (2x3s) @ 3.1A is 104W max (with a 25% charger efficiency figure added in). Charging two of these pack arrangements requries 208w. And that's at the max 4.2v/cell, so most of the charge require lower currents.

For 208w: At 12v, that's 17.3A. But at 14.8v, that's 14A. Pretty close if you can tweak the output of your existing one to 14.8v.

If you reduce your charge current to 1.8A, you can still use your existing PS (without voltage tweaks), but will obviously increase your charge time.

If you can tweak your current output to 14.8v, you can charge dual 3s+3s packs at 2.2A and stay at the 10A limit.

Or, mod a computer PS...
