Antigravity Batteries YTZ7-S 8-Cell 240CA Lithium Battery

This is the 8-cell high-power version that comes in the OEM YTZ7 Case format. It has 240 Cranking Amps and is a direct replacement for the standard YTZ7 Lead/Acid battery found in so many bikes including most Enduro bikes on the market. This battery is about 50% lighter than the stock Lead/Acid battery while providing more Cranking Amps for much better starting. If you have any modifications or desire more power and more capacity you should leave the old technology behind and choose Antigravity.

Antigravity YTZ7-S 8-Cell 240CA Lithium Ion Battery 5 5 1 1
Best Battery Yet I replaced the stock Yuasa lead-acid YTZ7S with a Shorai LFX14L2-BS12. It was a marked improvement, turning over the engine faster and improving start time. This Antigravity YTZ7-S is even better. It spins the engine faster and the engine now fires immediately. It never did that before. Awesome battery. October 20, 2014
