Tattus are really nice, but they can be pricey, graphenes work really well, and nano techs aren't bad either, Nanotechs are a little cheaper than the Tattu and Graphenes, any of them would be a good choice, I do think that Tattu would be pretty durable, as well as the graphenes, they both seem to have some protection measures built in such as the steel plates in the Tattus https://www.amazon.com/gp/aw/d/B005MW0WZO/ref=mp_s_a_1_1?qid=1462293523&sr=8-1&pi=SX200_QL40&keywords=4+channel+lipo+rc+charger&dpPl=1&dpID=51u7%2Bki0NRL&ref=plSrch

That's the charger I use, however I think there's a 1 channel version if you don't need 4, it does a good job though and will automatically trickle charge(it basically drops the amps when the battery gets closer to full, pretty standard thing for lipos, you can fast charge if needed) and balance well

Also have you already built it ? I run raceflight and it's a night and day difference you may want to look into getting a CC3D revo to do raceflight
