12V 100Ah Lithium Iron Phosphate Battery LiFePO4 Rechargeable Camping RV
These have pouch cells and are usually sold as 'Gentrax' brand. They arrive with Gentrax branding on the batteries and a Gentrax user manual. Comes with bolts for terminals in a secure package brand new with wrapping tape. I believe they're the exact same internally as the Adventure Kings 100Ah but have yet to see someone tear down those for comparison.
Here is a teardown of the Gentrax shown here. https://imgur.com/a/gentrax-100ah-06-2024-8lnWTqM
I have personally tested these in parallel (3 batteries) and pulled 315Ah. Meaning these are 105Ah each.
EDIT: If you need multiple, now's the time. I've just added 3 to cart for a $505 total. $168 each. This is an all time low price.
The BMS on this won't allow 200A at all, CMIIW
