Are there any battery holders on your site that will fit this cell, I didn't find any when I looked through, but I might have missed one.

Sorry, it took us a bit of time. Holder is now available and listed below.

Thanks, that holder will work. I now have a 2nd question. As I looking into Lithium-Ion recharging, I'm learning that you should have a protection circuit that protect from over-current and over-voltage draws. Seems like this circuit should be in place when charging or discharging the battery (I noticed the lithium pouches have this). Could sparkfun provide a simple protection circuit for use this this battery and some of your other lithium-ion batteries?

The protection circuit does exactly what you said -- prevents overcharge, overdischarge and short-circuit. If your own charge-management is guaranteed not to do any of the above, you will be fine.

Keep in mind that charging these batteries in series can lead to overcharging. (8.4V total does not necessarily mean 4.2V each)

Can I use PRT-00726 LiPoly Charger to charge this battery?
If not, how to charge PRT-08818? Is this battery suitable for a SD card based data logging system?
