Get this bad boy, it is great. You can charge 2 2s packs at the same time, and they can be different Mah as well!
Max rate is 1.8amps at the 2 amp setting, but that is fine for the smaller lipos. Plus it charges each cell separately so no need for a balancer. I have one and use it all of the time, especially when reconfiguring packs that have way out of balance cells!
Get 2 of them and 3 pairs of 2s packs and you can play all day!
