Anyone using these Antigravity ReStart Lithium Ion Batteries? Opinions?

[Gilda]

I was searching the internet for local suppliers and came across this one:

https://www.ablithium.ca/product/13-...ry-utvs-boats/

its rated at 12ah but has a 700cca which is twice that of the oem battery. They also list a 8ah that has 420cca and is quite a bit cheaper.
They are obviously a local chinese battery reseller but it has a 5 yr. warranty? Local dealers, Calgary and Edmonton.

I have a call in to them to get more detail so not a recommendation at all just a FYI.

Thanks, Andy!
