i had some doubts about these little lithium batteries until i started using them.
When My Ultra 4 car was built I had the builder install a pair of odyssey metal cased Gell batteries. After a couple of years of bashing the race car in the desert and on the rocks the gell batteries had some leakage. So I installed a pair of the exact same lithium batteries you see in my superlight into the ultra 4 car. I dont have a pic but 2 of the lithium batteries fit into one of the gel acid battery boxes. included is a pic of the gel batteries before i installed lithium. Note that after installing a pair of Li into a single battery box i was able to remove the 2nd battery box.
these lithium batteries have been in place for 4 years now (on a tender when not in use) and still work like new. I only use one of the 2 batteries in the U4 car during normal use (car also has a back up fuel pump with a separate fuel filter as seen in the pic). the 2nd battery is a spare and i can activate it with the rotatory switch you can see in the headliner of the U4 car. (or i can activate both batteries at the same time). The u4 car has a crate LS3 485 hp and one of these lithium batteries can crank it easy. At the same time as engine management, I have had no problem running lots of lights, a parker pumper, gps/nav, data logger, etc all on a single battery. I was worried that the small posts on the antigravity battery would be problematic but this has not been the case- I bounce the piss out of this brand lithium battery and they stay together tight.
