Specs - 3rd bullet down - "Charges: 1 to 25 NiCd / NiMH Cells, 1 to 8 Cell Lithium, and 6-24 volt Lead Acid/Gel Cell Batteries". You won't find a 10amp hobby AC/DC charger, they're usually always limited to 50wattts output power. CHeapest 10a charger I know off - Hyperion 0610iNet, $150. Needs a 20amp continuous rated power supply, so another $50-70.
Downside to a large capacity lipo like these is the weight, these weigh a lot relatively speaking, look at some of the listed weights and compare to 5000mah size. They're also physically large - be sure you can make one fit. I'd get them direct from TrueRC rather than pay a middle man.
TrueRC makes up for its low C rating with the bigger capacity so it can still deliver the amps. From what I've read, their C Rating appears to be conservative, not the other way around.
