Battery Charger for 2S 3S LiPo Battery, Balance Charger for XHR Plug Battery, Lipo Chargers for RC Toy & Model, RC Battery Chargers with Smart Chip

I double checked and the battery that comes with it is a 2s style battery with the main lead replaced with a barrel power connector. The smaller cable is the balance lead and how you'd connect it to charge. If you don't want to get the vifly you can get something like this that will work. Personally I'd get the vifly over a cheap charger but this is a cheaper one to get you going. https://a.co/d/0h9oFVYG
