Hey there, Well I got my 4X4 last week but had to wait for things to dry out (today) to get the tires dirty for the first time................ Fresh outta the box it runs waaaaay slow for about two pulls of the trigger then acts like it's quickly loosing charge. The third pull of the trigger makes it sputter and surge. I took it in to the garage and put a fresh battery in it and got the same result. I plugged said battery back into the charger and it showed 7.14v. I check to see if low voltage detection was disabled and it was. Any idears?
