Can anyone confirm if this will work with Vernier's Wireless Hand Grip Heart Rate monitor?
That comes with a special wireless receiver that usually connects with other Vernier interafaces like GoLink etc. via BT connector

Are these fine to use without batteries as well? I'm building an exhibition with a whole lot of Arduino Pro Mini's and was thinking to use them connected to the USB ports of the computers that are connected to each one? Seems to work when I tested it - but not sure how it would be after a few days of continuous running?
In a show I ran last year - I had these connected to a 1000 mAh Li Polly - usually I'd leave them to charge overnight then let the Arduino Pro Minis run on the battery - occasionally I'd have to leave them pluged into the computer - in effect - charging for upto 48 hours.
One of my li polly batteries looked very swollen and puffed up at the end of this show - not sure if it was because it got left on 'charge' too long - or what…
Any recommendations would be most welcome
