I see posts on this Forum for JJN solar panels but nothing for their LiFePO4 batteries. Are they any good??

Also found the Elfhub

I was looking at amazon and found these are they any good or just crap??:

JJN 12V 100ah Lithium Battery 1280Wh Low Temp Cutoff LifePO4 Battery 100ah 8000+ Cycles Times Deep Cycle Battery Built-in 100A BMS System Perfect for Solar Home Energy Storage RV Camper Off Grid - $209.99​

Elfhub 12V 100Ah LiFePO4 Lithium Battery, Upgraded 100A BMS, 10-Year Lifespan with Up to 15000 Cycles, Max. 1280Wh Energy - $209.99​

Price is $209.99 which is amazing but only if they are as good as the LiTime 12V 100Ah TM LiFePO4 which is currently priced at $339.00.

At this price I would buy 2 but not if they are crap, would love to see a video of someone cutting these opened and doing a product test on it just like the LiTime battery.

I'm curious if anyone knows about the Elfhub.

This one states heating function in the initial product info on the top of page but nowhere is it mentioned in the specs.
If I bought one I would fully charge it then put it in freezer....then see what it REALLY has in it.
If full of promises and nothing more, return it.
