I wouldn't say efficiency is 'much' higher, it is higher yes, but as an example, say if the 5s2p system was 89% efficiency, then the 10s system would be around 90.5 - 91% max efficiency. And you are right, every point higher the % efficiency is, turns up as a noticeable difference as far as heat in the wires a bit, and motors would run a touch cooler, and the runtime will increase, but not noticeably.

But ya, go for the HV setup of course. What are you using to charge 10s A123? Are you going to have them as 2 separate packs charging separately, then connect them in series for running?
