Blows my mind how light these are. On my second one
Used my Lipo model plane charger to top it off when I got it. Feels like empty box but is more powerful than my lead acid batteries. Love the extra battery post for wired in charging wire. Plus you can put battery in with Pos on right or left. Plus comes with rubber spaces so you can change the hight of how it sits. Something so simple and useful. Worth every penny. Will NEVER buy the old style again.
