Any one have any experience with the XS Power S-1600 light weight 16 volt AGM battery. I run a SBC in an altered in the T/D class with no alternator. Engine is normally aspirated 434 CI 16 to 1 compression and the car has a MSD 10+ ignition, trans brake, shifter solenoid, and delay box. My old 16-V battery (Lifeline) has died and the 12 to 14 pound weight savings of this battery would be cool if it had enough grunt. Thanx Lary Alvey.
