AGM or Li-iron?

So I am about ready to pull the trigger on a new battery. Down to 2 choices.
The Shorai - Shorai LFX14A4-BS12 Lithium-Iron Phosphate (LiFePO4) Powersports Battery

The Shorai looks really nice on paper and appears to be the best choice, BUT it's 2 times as expensive as a good quality AGM lead/acid.
AGM 12V 10AH

After a bunch of reading, the westco batteries look to be very good quality AGM batteries, but if the Shorai truly gets 2 times the lifespan, especially with no maintenance (which is what I plan on) then it's the batter value.

Any of you AGM guys who don't maintenance, I would like to know lifespan.
You Shorai owners, I would like to know lifespan on yours also.


oh, the weight savings isn't a big deal to me. 5lb doesn't matter to me since I'm not putting the thing around a track. I need to lose more weight myself before I worry about 5lb on my bike.

another question I guess. Anyone have any experience with the super el cheapo agm's on ebay?

$27 is pretty cheap and leaves me with a good chunk of cash on the way to chain/sprockets

I have a Shorai LiFe. Been nothing but happy with it, had the bike sitting for 2 months through winter (outside) and bike fired right up with one thumb of the starter. You do however have to take her out for a ride to recharge... I made the mistake of checking several nights before I planned on going on a ride by starting it up to see if it still had juice. Fired right up no problem; didn't let it idle for more than a minute... come ride day, swapped oil and tried again. Battery was dead

So while a tender on a stock battery will be your best choice for a FOR SURE start and restart, the Shorai will fire right up as well but you do have to take it out for a ride to charge.

Shorai has weight savings (2lbs) and is much smaller than the stock. You'll have enough room for the factory tool kit in there.
