battery selection

[mslaffin]

Some things to think about:

• Power management devices mostly limited to single cells
  • the BQ24180 also refers to "battery pack", but this may only refer to Li-polymer?
• Common characteristics for single cells
  • 3.7V nominal voltage
  • 4.2V full charge
• capacity
  • probably not more than 1-2 Ah needed
• discharge current
  • [ ] system power requirements
• integrated protection
• form factor
  • I like how DSLR-type cameras put the battery in the grip. also gun-style infrared thermometers do a similar thing
• connector type
