Rechargeable 55mAh Li-Po battery
1. Long cycle life
2. High discharge platform
3. Factory sale price
4. One year warranty
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.
