I don't have any chargers outside of the 3.7v 1 cell chargers that usually come with the park flyers I have. This one battery is something I might, maybe, use a couple time a year so I was hoping to get something simple and cheap, especially since the battery itself was only $5. Everything I look at, though, is 3-pin so I don't know which wire I could conceivably eliminate in order to charge.
