It is from Antigravity Batteries. If you'd like to read a ton of user experience on LiFePo4 batts in general on motorcycles, there's some huge threads on the advrider forum. I've used a couple of 4 and 8 cell ones on bikes.

 

Wow thanks, I didn't know antigravity existed, they are cheaper than the other lithium batteries I've seen, but lithium is still pretty expensive in my opinion.
I want their smallest one the 4 cell, http://www.racerpartswholesale.com/p...atteries/?r=gs

With my supercapacitors it would be perfect, but pretty pricey for a little tiny battery that costs as much as my full size lead acid battery. I dunno yet but at least I know it exists now.

I'm also pretty sure I can design a unit now that weighs 2-4 pounds and cranks as good, maybe better in the cold. But I'm going to have to wait till I need another cuz I already bought these, but I'm pretty satisfied for now.

 

Hi guys , did anyone already tried the "mini" version of the super capacitors bank? I'm talking about the 350F boost cap comprising the pcb and the balancing circuit that you can easily find on eBay..
