High temperature 3.7v 2000mAh Polymer Li-ion Battery405580

Specifications

Features of Li-Po battery: 

• High energy density                                                         

  Weight of liion battery is half of the  Ni-Cd  or NiMh battery with same capacity,volume is 20%-30% of NiCd battery and 35%-50%NiMh battery.

• High voltage

  Voltage of one liion battery cell is 3.7V(average value),it's equivalent to equivalent to three NiCd or NiMh battery cell connected in series.

• Pollution free

  Liion battery do not contain harmful metallic substances such as Cd,Pb,Hg and so on.

• Excluding lithium metal

  Liion battery do not contain metal lithium,so it's not limited by the rules on the aerobus of prohibit to carry lithiun battery. 

• Long cycle life   

   In the normal condition,the cycle life of lithium battery is more than 500 time, LiFePO lithium battery can reach to 2000 times

• No memory effect

  Memory effect is a phenomenon of the capacity of battery reduced during the cycle of charge-discharge.Lithium battery absent of this effect.

• Quick charge Charge with a 4.2V nominal voltage and constant current and voltage charger,it only take 1.5-2.5 hours to be full charged.
