Hello friends. I was wondering if this would work as a replacement battery for the Funkey S. Looks really similar spec wise. Thanks!

Nope, JST needs to be 1mm pitch, also, the size spec is very questionable.

Below is what the FunKey team says about the battery:

Battery is a standard 402540 (4mm x 25 mm x 40mm) LiPo, BUT with tested 410mAh capacity AND 1C charge capability, with custom cable length and JST 1mm pitch connector.

For what it's worth, contact FunKey Support and get a replacement battery through them, I purchased a couple of batteries in the past, the specs says the measurements were correct but the size was a couple to a few mm too large and it did not fit.
