    DCDC 25A Charger

    Plug and play made it very easy for installation to the HD 8mt battery lead kit that I already had installed.

    Great Features

    Does as it says on the box.!

    Great dc charger with a very useful blue tooth functionality.

    It’s nice to be able to change setting via the app. It enables you to change charging rates and see what the charger and battery are doing.

    My only gripe , is that the blue tooth disconnects frequently , but I’m assuming that this is a battery saving feature. It does reconnect quickly when need tho.

    Overall, very happy with my purchase.

    Great bit of kit

    This is my first foray into DCDC chargers and lithium and you literally couldn't make it any easier than what KickAss have made it short of paying somebody else to do it entirely. Grab the wiring kit and you'll be up and running in no time.
