Battery - Flooded vs AGM vs Gel

Thinking on this, I don't think they come with a battery from the factory. I'm not 100% sure, but I believe the battery is part of dealer prep, so it would come from the dealer with a battery, but not from the factory with one.

Mine was within the free replacement period, I think. Looking at my old emails, I had had it for just a hair over eight months.

Ahhhh... I thought they were AGM (should have done my homework). I did not realize they were LiOn. That does change things somewhat, but not to the point where a SOC below 12.8v should be considered abuse, and void the warranty.

The Shorais are LiFePO4, not regular old Lithium ion like laptops, phones, etc. use.



Their biggest advantage, and arguably their biggest disadvantage, is that their discharge curve is almost flat until they're completely done.

Well, excuse me while I wipe the egg from my face...

Thanks for taking the time to educate me, Kit. But, those numbers don't seem like they would be a good match for the charging systems on our bikes. With a target charging system voltage of about 14.2 volts the battery would barely reach a full SOC.
Although, now that I think about it most Hybrids are designed to keep their high voltage batteries at about 85% SOC. So I guess this isn't much different.

There. I learned something today.

Always happy to help!

In practice, it worked very, very, well for me until my charging system went out.
