Got to thinking... source of cheap 3.7v Li-Ion Cells...
 

I have one of those wristwatches that doubles as an FRS radio...

The battery is a 3.7V 540mAh, it's about 3/16" thick, 1 7/8" long and 1 1/4" wide.

looks like these:

You know what I'm thinking. :D

Plus, I don't need to buy or build a charger. just put it back in my watch and plug the watch into it's charger.

Audiovox wants $22 plus about $7 shipping and handling, but I bought my FRS Watch for $19.99... so the heck with that. Go to the FRS radio aisle at walmart and you'll see lots of little FRS radios with these batteries.

can you please post a pic of your radio watch thing

I may pic one of these up they sound cool
have you come up with any ways of attaching it to a bit
withought sodering it on so you could recharge it

Well this is a WASH. :(

The battery is so huge it won't fit in anything 1:64 or smaller unless it's a friggin ocean liner.

pics pics... hmm... here we go:

Audiovox GMRS200W

22 Channels (14 FRS, 8 GMRS), GMRS License required to legally use channels 15-22 in the united states, available for $75 from the FCC.

Approximately 2 mile range. Voice activation, channel scan, backlight, "roger beep", and clock. Comes with One 540 mAh 3.7V Li-Ion Cell, handsfree headset, and a charger that plus into the headset port. Completely charges a dead battery in about 5 hours. With just the watch mode on and no FRS, it will go about 3 weeks without a charge. FRS in standby mode with no scanning lasts about 3 days. If left scanning, runs about 2 days. moderate FRS use (like on a road trip) will pull runtime down to about 10 hours. The charger inside IS a smart charger, so it won't overcharge the Li-Ion battery. Not bad for $20. There's another similar watch made by X-act that uses the same batteries, and several miniature FRS's made to be worn like pendants, also from X-act with the same battery.

The only thing this FRS is missing is "privacy" codes.

I have about 5 or 6 FRS's, this one is certainly not my primary one, but it's one of my favorites.
