Batteries
Chose conventional, non-rechargeable alkaline cell
- simplified initial power system design
- good specific energy (W-hr/cm3 and W-hr/kg) and specific power (peak W/cm3 and W/kg)
- available in airport lobby shops
Chose pair of AAA cells
- smallest size that met peak power requirement (2W MAX)
- no minimum energy requirement/specification!!!
- this decision minimized size/weight of base system
- those who need longer run times can use larger cells
