A couple days ago we received a large order of very good smart chargers from SkyRC. These chargers are rated for use with drone batteries so they'll have no trouble charging our airsoft batteries. I have to say, I'm very impressed with how quickly these smart chargers can charge batteries.
If you're using a high performance LiPo battery, you're gonna want one of these. These ones give a faster charge, more balanced charge and less explosive results than a standard charger that only has a couple lights to protect your battery from a fiery end.
Honestly, I cannot recommend them enough, we've got quite a few in, but if it's anything like last time these will fly off the shelves. Hopefully, if you get one, it'll prove it's worth through the absence of fire in your home.
