The feature of the LifePO4 Battery:
The experiment of overdischarge to zero voltage was carried out with the lithium iron phosphate battery 26650(3400mAh) .
 
Test Conditions: the 3400MAH 26650 battery was filled with 0.5 c charge rate, and then discharged with 1.0 c discharge rate to 0C battery voltage. The 0 V batteries were divided into two groups: one for 7 days and the other for 30 days, and then charged at 0.5 c and discharged at 1.0 c. Finally, the differences between two kinds of zero-voltage storage period are coared.
The result of the test is that the battery has no leakage after 7 days storage, the performance is good, the capacity is 100% ; after 30 days storage, the battery has no leakage, the performance is good, the capacity is 98% ; after 30 days storage, the battery does 3 times charge and discharge cycle, the capacity is restored to 100% .
This test shows that the battery even if there is over-discharge (even to 0V) , and stored for a certain time, the battery is not leakage, damage. It's a property that no other lithium-ion battery have.
 
SO, the advantge of this kind of battery is as following:

• High efficiency output: STANDARD DISCHARGE IS 2 ~ 5 °C, continuous high current discharge can reach 10 °C, instantaneous pulse discharge (10 s) can reach 20 °C
• high teerature performance: external teerature 65 °C, internal teerature up to 95 °C, battery discharge end teerature up to 160 °C, the structure of the battery is safe; even if the battery is damaged inside or outside, the battery does not burn, does not explode, has the best safety;
• excellent cycle life, after 500 cycles, its discharge capacity is still more than 95% ;
• Fast charging;
• low cost;
• no pollution to the environment.

Application:

• Large Electric vehicles: buses, electric cars, tourist attractions and hybrid vehicle;
• Light Electric Vehicles: Electric Bicycles, Golf Carts, small flat battery cars, forklifts, cleaning vehicles, electric wheelchairs, etc.
• Electric tools: drills, SAWS, lawnmowers, remote-controlled cars, boats, aircraft and other toys,
• solar and wind energy storage equipment, UPS and emergency lights,
• warning lights and miner's las (Best Safety) ;
• Replacement of 3V disposable lithium batteries for cameras and 9V nickel cadmium or nickel hydrogen rechargeable batteries (exact same size) ;
• small medical devices and portable instruments.
