The FL-1625 battery was designed specifically for the racer looking for a 16v battery W/ TOTAL LOSS Systems (Racers running with no alternator) in mind, that did not need long run times or big capacity. 

This battery has massive cranking amps to start even the toughest engines, and run systems with minimum draw, like delay box, auto shifter, shift light, etc. Used in Blown applications utilizing a crank starter with carburetors.


A great choice for Pro Mod, Outlaw 632, Top Dragster, Top Sportsman, along with many Mud and Dirt drag racing classes not using big Nitrous systems.
