Mini thumper

I had the previous agm thumper and always said that if they brought out a lighter lithium equivalent it would be perfect. I was not wrong! This little battery is awesome, weighs next to nothing and will run camp lights, charge phones and a 12v fan all night. Best part is it will charge super quick at 5+ amps per hour with the standard cig/anderson lead supplied. Great product Home of 12 Volt. Not many other little lifepo4 batteries around like this that can be charged up quickly.
