i have some experience in this field, i have a triton 2 lipo charger from electrify, good price about 120$, this charger that i have can charge up to 7amps, more than enough to get you going. or if you want to go more modern and top quality and want to charge two batteries at the same time then good with hyperion duo charger, it is more expensive like 296$ on amainhobbies.com. but there is less waiting involved.
