So I decided upon the Turnigy nano-tech Ultimate 4600mah 2S2P 90C Hardcase Lipo Short Pack because I was able to get it to fit inside the WL Toys 12428.
First thing I did was to plug it into my charger and charge it to capacity (at 1C which is 4.6A) and it ingested about ~3500 mAh in ~83 mins. The charger is a SkyRC iMAX B6AC V2 and is connected to my Ubuntu pc running GNU DataExplorer:
But the real test is discharge. On paper my battery charger/discharger maxxes out at 2A discharge, but I was only able to get it to discharge at 0.6A .. not sure what's going on there.
UPDATE 1: Real world test; since I installed these packs (two cars) we've been out for two RC adventures, we kinda played till we'd had enough and came home, and in neither case did we run out of battery ;) I didn't time it, but I'd say we had fun for 90 mins or more. Very impressed.
