What makes you say they’re the same chemistry? If these are indeed semi-solid, then I think we can conclusively say the chemistry is not the same as a Li-po. (I have noted that their marketing literature refers to “solid-state”, which AFAIK makes no sense when it comes to batteries. I attribute this to translation issues.)
Semi-solid lithium batteries are already being mass produced so it wouldn’t surprise me to learn that Foxtech managed to get a few cells for the drone market. I do not have one of these batteries, so can’t drive a nail through it to test. Right now, I’m giving them the benefit of the doubt, coming from a combination of sales literature, cell test documentation, and prior experience with Foxtech.
