I am looking for someone with some experience with them . I can get one for a good price but I am wondering if it will still leave me wanting a icharger duo setup . I race stock class mostly (17.5 buggy and 13.5 4wd buggy) and I am most interested in the discharge side of the charger works . It says it will discharge at 30a but do you need something else to utilize the 30a discharge(discharge bank or deep cycle battery , etc..) . I can get this charger for a lot less than a 406 duo and a discharge bank , Currently using a thundepower and power supply that will charge at 20a mostly looking into a new charger because of the discharge features and my thunder power is starting to act a little funny sometimes? Any feedback on sd1 charger is appreciated thanks
