Review on Crimp Supply Ultra Flexible Battery Welding Industrial Power & Hand Tools: Unparalleled Versatility and Durability by Marcus Hargrave

High quality 2/0 welding cable and copper terminals. I used it to connect the Axillary golf cart battery in my van to the power rails that power my inverter. If you are drawing more than 2000 watts from a 12 volt battery, you should use 2/0 wire, good quality copper spade terminals, battery fuses, marine grade tires and switches. The high current of 12 volts generates a lot of heat and can immediately cause a fire in the event of a short circuit. The last thing you need in an RV or boat is an electric fireplace.
