That's what I would have bought if my LHS stocked it, but that should work nicely as long as it comes with the JST 2-pin red connector. As for a charger you will need one, typically if you have a 1000mah or milliamp (1 amp) battery, you want to charge it at 1 amp, 2000mah at 2 amp, etc. I bought a generic trickle charger that had a few options for .5 amp, 1 amp, and 2 amp, and multiple connectors. As soon as I track down a rechargable pack for my transmitter I should be able to charge both RX Pack and TX radio on the same charger (not at the same time though).
