[RE-wrenches] Huge battery bank recommendation

[Ray Walters]

Consider the HUP Solar One battery, the 125-33.  It has 2490 AH at the 
20 hr rate.   The warranty is for 2100 cycles to 80% DOD.  Also most of 
the jumpers are included (bus bars within each 12 v group)
We've had nothing but happy customers since we started using the HUPs.
