There's a few posts about them, if it helps.

There is some indication it's the same as Sun-Thing28, which means these posts
https://endless-sphere.com/forums/search.php?keywords=%22sun-thing28%22&terms=all&author=&sc=1&sf=all&sk=t&sd=d&sr=posts&st=0&ch=300&t=0&submit=Search
also apply, as do these:

and probably others.

you can also list those by topic rather than post if you redo the search with the same terms.

Their LIfepo4 batteries are pretty cheaply priced.
Generally cheaper = cheaper for a reason. If a price seems too good to be true it probably is. Sometimes it's that the original item wont' be as good; cell origin / quality unknown, etc. Sometime's it's that service later if needed wont' be as good or at all, or warranty won't be honored, etc.

Unfortunately costing more isn't a guarantee of goodness, either, but it's a better bet where batteries are concerned.

Lifepo4 is twice heavier, twice volume than INR. So only good for home energy storage.

You left out all the pros of lifepo4. Like the fact it has more cycles then 18650 or Lipo or the fact that it voltage does not slowly drop over use instead dropping till the very end when its almost dead. Or the fact that it is the safest of all chemistries. i have cross wire my lifepo4 pack 3 times during a few mistakes had that been lipo id have a fire.
