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.
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.
Liion battery do not contain harmful metallic substances such as Cd,Pb,Hg and so on.
Liion battery do not contain metal lithium,so it's not limited by the rules on the aerobus of prohibit to carry lithiun battery.
In the normal condition,the cycle life of lithium battery is more than 500 time, LiFePO lithium battery can reach to 2000 times
Memory effect is a phenomenon of the capacity of battery reduced during the cycle of charge-discharge.Lithium battery absent of this effect.
12 month quality warranty,if there is any quality issue in our battery,we can send you free replacement.
