I use these for making NiMH packs,

Makes it very easy to build very low resistance packs and also when you want to reconfigure packs,make saddle packs etc.I also only use GP2200s for NiMH cells,they're 4/5 subCs,shorter and lighter,just lets you fit more voltage for the same space and weight compared to subCs(3700s etc).
I think you'll find it really easy once you get started with this stuff,once you get a BL setup up and running (which will be easy if you follow peoples advice and get a set up that is known to work for what you want) then there's much less of the pulling your hair out moments that come with nitro RC.Also,besides the power plant, electric vehicles are much easier to maintain in general since they're not constantly vibrating themselves to bits and covering themselves in sticky fuel.Much better playtime:downtime ratio.Also it's the only choice for real horsepower freaks.
You don't need that much technical/electrical knowledge to start with either really,you can just ask lots of questions and people will keep you right.
