Can someone explain best way to charge specific lipo
 

I have a Thunder power 3 cell 11.1v 2100mah lipo battery and a Triton battery charger and I am not an electric guy. I was hoping someone could explain the best way to charge that battery with that charger?

I don't know this charger, but you should only charge LiPo's with a compatible charger and the consensus seems to be at 1C max

First read the directions that came with the charger. Learn how to set the charger for lipo. You don't want to charge it with a NiMH setting. That will overcharge it. Set the charge current to 2 amps (about 1c). It will take a little over an hour to charge. When you get more experience with it you can charge at 4 amps(2c). "C" refers to capacity. In you case that's 2100 mah, or 2.1 amps.

I use the same packs in my airplane. They're great as long as you treat them well.
