There's a new heavyweight in the ring: the iCharger 4010Duo. With two channels available, each of which can charge at up to 40 amps simultaneously, it's like having two superchargers in one. Or combine both channels in parallel to achieve up to 70 amp charge rates!
With two JST-XH balance boards thrown in for free - one for each channel - you'll be ready to go right away.
