Just got back into the electric stuff and bought this slash used with the VXL system. Im new to the lipo stuff so I had to buy battery's and charger and from what Ive read I seem to be doing all that correct. When I drive the truck I get about 5 min and then it cuts off. I have to walk over to truck and push the button again on ESC to turn it back on then it runs a while and does it again. After doing this a few times it will start to act like the battery wants to die and than loose all power for a few seconds than run fast again. What am I doing wrong or is it something Im over looking?
