| Thanks! — In the current ones we’re shipping right now, the battery is one of those thin lithium primaries, ~0.45mm. But, in the version that’s coming out, we’re coating the anode and cathode materials on two different substrates and laminating them together on a reel-to-reel process. — They’re pretty durable, but they are labels (laminated polypropylene and PET) with a very thin layer of polyurethane foam less than 0.3mm. Water resistant: yes, but underwater, probably not. Those that are shipping now aren’t fully hermetically sealed, but the next version will be, as the lamination stack-up forms part of the battery pouch. — Yes, they are flexible. The only issue we’re having at the moment is their thickness of 0.5mm and dissimilar materials of the stack-up causing some pulling-back of the laminates around really tight radii. But, we think we’ve solved this in the next version, targeting an overall thickness of 0.3mm and different materials. — The battery level is something that’s included in the beacon message, and is updated once a day. |
EDIT: Found your website, ordering a few now. Can't wait for android support!
