Well folks all has gone well, rig's almost done, and I’m at that precarious position now of buying my batteries. The best deal I’m getting here in the northwest appears to be the Crown battery GC 225 at $104 each, with no core charge and delivered! X 20 that’s still a hefty sum!! Has anyone had any experience with these cells? All input would be appreciated. Go to crownbattery.com for info.
