100 a/h Lithium Battery for $21?

There is no way any legit business can sell multiple 4-unit pallets of items normally costing $600-$1,000 EACH items for only $82.99 for all four. While there is a microscopic chance someone could stumble onto such a deal in the case of someone with them just wanting to get them the heck out of the garage/shed/extra bedroom, I think you have to stretch your chances beyond all possibility in order to find a legit deal of the sort offered in the ad, which, btw, has been showing up on my Facetube feed frequently of late.

I have not bitten because I am certain enough it is a scam to not bother risking, er, throwing away $82.99.
