Polyquest advertises only serial batteries (no parallel) to obtain higher capacities. So, they simply use higher capacity cells. The advantage they claim is that since you have no parallel cells you do not have to worry about balancing the voltage on cells, etc. I can see this is an advantage, but how big of a deal is it? I've only used 1P Thunderpower batteries to date but now need a 6000mah battery and am wondering if I should switch to Polyquest.

One advantage I can see is that with only two cells I could still use my Triton charger rather than switiching to something such as the Astroflight 109 that can handle more cells (the Thunderpower 6000mah is a 3S4P 12 cell battery).

Any cons to the Polyquest solution?
