-  * **Lithium Polymer** (Li-Poly) – normal voltage 3.7V – fair operating temperature range (down to –20 deg C see [[http://www.ibt-power.com/Battery_packs/Li_Polymer/Lithium_polymer_tech.html]]) – excellent current handling characteristics – with AA sized cells (not that Li-Po cells are normally that shape)  Capable of sustained loads of several 100s of milliamps and peak loads into amps. The big advantage of these cells is that they are re-chargeable (with the right charger). These have about half the energy density per unit weight of Lithium Thionyl chloride/Photo Lithium/Lithium Iron DiSulfide. Li-pos are well known for how easily they combust. Charging and discharging too fast, discharging too low and puncturing can all cause fire or explosions.
