I'm running 1512 2d/f on Polyquest 4S 6000mah geared 15/46. So far no heat issues and this thing is a bullet. It was cutting down weeds all over the yard.
Interesting that you only put the shock socks over the springs. I like to have mine cover the entire shock, getting dirt into the threads on the shock body is a PITA when you have to adjust the preload.
All I ever wanted was an honest weeks pay for an honest days work.
