The retailer (Batteries Plus) stocks a direct AGM replacement (Xtreme Permaseal, Taiwan). I like that it is AGM, but am hesitant to get an off-brand.

I'm considering a LiFEPO4 (Shorai, Antigravity, etc), but researching that is giving me a headache. The plus side is that I can put a more potent battery in the same space.
I researched this ad naseum a year ago, and took a LOT of notes on my learnings... see my linky HERE and search for Battery:

And here is the shorter version of my LiFePO4 mod I ended up with including pictures.

Keep in mind that this was a year ago and much has changed with the LiFePO4 vendors, quality, etc.

Hands down I would get a LiFePO4 (let's just call it Lithium) if I was to do it again. Simply because of the high cranking capacity and the fact that lithiums are SO small you can get a lot more capacity that you really need. They are only good for cranking amps (as opposed to a deep cycle), meaning don't run them down by using accessories without the motor running, then recharge them, or you will have problems, this chemistry is only for cranking amps. I know this has let people down and some don't like them because of that. They are not the same as lead acid.
Also, if I rode in a really cold climate (well below freezing) I might also think twice. Those are the only drawbacks IMHO (besides $$$).

As to brands, it changes a lot. A relative new brand (from a Colorado company) is EarthX which I see inmate herrhelmet is selling is now selling instead of the brand I bought from him a year ago. It has some cool balancing circuitry built into it and I think that is the one I would buy, but I have done NO research on it's reliability which is key.

Matter of fact it's 10 degrees F outside (30 F in my garage) and my bike hasn't been started for a month, and I just went out and started it up, fired up on the 2nd crank.
