Anyone know about this lithium battery brand?
This deal looks almost too good to be true. A 200 Ah Lithium battery for $450?? Brand is Wanroy. I know they make "solar generators" but can't find many reviews about the battery itself. Anyone have any experience with these?

I didn't see any mention of the BMS being able to protect it against low temperature charging. LFP batteries should not be charge when the internal temperature of the battery fall below 32° F.....might be something to think about if you use them in cold weather environments

I did find a YouTube video (in German) of a teardown of the battery. https://youtu.be/MMaFnWql9_0
Apparently it has a high and low temperature cutoff. The sensor is in the case. Guy used a heat gun on the sensor and it cut the battery off. Also used freezing spray and it also cut the battery off. Wish I understood German to get all the particulars, but it appears the reviewer liked the battery. Not sure if the BMS shuts down charging based on temperature also (again language barrier)
Another tester of the battery without teardown https://youtu.be/oY5_MnxgqAg Reviewer gave a thumbs up at the end of the video.
If anyone speaks German and wants to take a few minutes to watch these reviews it would be greatly appreciated.Frank & Nadine

It's not german, it's fraenkisch (franconian dialect)! Big difference - for the franconians!
As you mentioned already, in general he likes it. He was a bit surprised about the internal parts, expected a little bit higher build quality, but still ok.
By the way, the auto generated subtitles at Youtube (when available) work surprisingly good and should be enough to get the gist of most reviews. Settings symbol in the lower right corner of a video, and select Subtitile --> Aut- Translate. Then activate the subtitles with the "CC" button next to the settings symbol.

Thanks for checking that out. Didn't know there was fraenkisch. Is that like American vs British English or Northern vs Southern ya'll?? I did find the CC translation option and watched both videos again. To me it seems like an okay buy considering the extra 24-30 Ah from the rated 200Ah and it's only $450
