SKU: TH0820
Lithium-Ion Polymer (a.k.a Lipo or Lipoly) is a reachargeable battery that uses Lithium Ions, similar to a standard lithium-ion battery. However, instead of a liquid electrolyte, it uses a polymer electrolyte which is a highly conductive gel that allows lithium ions to flow between postive and negative electrodes. Lipo batteries are lightweight, thin and can have a higher engery density into a small space.

This is a 3.7V 40mAh Lithium-ion Polymer battery which outputs voltage ranging from 3.7V to 4.7V when completely charged. It comes with a 2-pin JST-PH connector, 100mm wire length and has a built-in PCM (Protection Circuit Module) which prevents the battery from over charging and over discharging by cutting off the output voltage at 2.75V. PCM also protects against output shorts.
Only use a Lithium Ion / Lithium Polymer chargers which provide constant votlage and constant current.
DO NOT use NiMH/NiCad/lead-acid charger.
DO NOT puncture, poke, fold or cut open the Lithium Ion Polymer battery, it may result in spontaneous fire or explosion.
