Running sledge and arma kraton. 3s lipo in both 5000-6500mah. What would u guys recommend for a dual charger that is relatively basic to use and not crazy expensive? Currently using traxxas dual charger, which works fine for my needs charging non traxxas batteries, but wouldn't mind a better charging setup. Fan recently started sounding awful and on its way out, very easy to replace fan though, just not sure of size, think it's 30mm
