Plus 1 on the Revolectrix Chargers (2 YEAR WARRANTY
Lifetime service repair) Best customer service in the industry. You can call there number and a real person will answer the phone. I use there bump control series chargers and they are the safest chargers in the market. I still get updates (usb) as they add new features. I could go on and on. If you plan to stay in RC for a while this is the only way to go. Merry Christmas
