RIDGID Battery DC-DC Power Supply

An easy to assemble DC-DC charger that uses your RIDGID or AEG battery as the power source. Using the DC-DC converter, you can set your voltage between 1.5v-18v and set a current limit of up to 12A. Perfect for charging or boosting dead or draining car batteries, ATV, lawnmower.. etc. You can use it to trickle charge or turn up the amperage for a more immediate charge. (NOT TO BE USED FOR JUMP STARTING).

With an SAE connector, you can switch between 12V plugs, alligator clamps or connect directly into a solar battery bank.

Note: The DC-DC converter had the screw terminals removed and wires soldered directly in place. You can also move the screw terminals to the back of the board to allow them to fit.
