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.    For small order we can ship the goods to you within 7 days,large order depend our stock,pls check with us.
