Motorcycle Batteries

[Grant H.]

Shorai is good.

Anti-gravity LI batteries are good. I currently have one of their RS series in my GSXR.

Super caps work on older/smaller bikes, but with my GSXR being FI, running the ECM, etc, even 500F super caps (6 in series, largest I can fit in the factory battery location) would only give me 2 attempts to crank, and with it being a cold blooded, it's not uncommon to have to start it 2-3x which makes the super caps iffy.

All LI types (lifepo4, LiPo, etc) are good to go until 32-35F, which is noticeably colder than I will ever be riding.

The biggest argument that I have for LI batteries is the longevity. I got tired of having to replace LA/AGM/Traditional batteries every 1-2 years, even with a tender, and have had my Anti-gravity for 3 years at this point with 0 signs of issues.
