Safety characteristics inherent to LiFePo4 technology result from the incorporation of phosphates as the cathode material. Phosphates are extremely stable in overcharge or short circuit conditions and have the ability to withstand high temperatures without decomposing. When abuse does occur, phosphates are not prone to thermal runaway and will not burn. As a result, LiFePo4 technology possesses safety characteristics that are fundamentally superior to those of Lithium-ion batteries made with other cathode materials.

LiFePo4 technology does not contain any heavy metals and does not exhibit the "memory effect" of Nickel-Cadmium and Nickel-metal Hydride solutions. LiFePo4 technology demonstrates excellent shelf life, long cycle life and is maintenance free.

1. High Performance
   High theoretical capacity of 170mah/g and high practical capacity as high as 165mah/g.
2. Extremely Safe/Stable Chemistry
   High intrinsic safety, will not explode or catch fire as a result of collision, over-charging or short circuit. High thermal stability of phases up to 500C.
3. High Rate Capability
   For all high power output application
4. Extraordinary Long Cycle Life
   Up to 2000 cycle life- over 8 times the life of Lead Acid and 3 times of NIMH, 2 times most Lithium batteries.
5. Long Service Life
   Around 5~6 years
6. Environmentally Friendly
   Non-toxic, non-contaminating No rare metal , UL, CE, SGS/ROHS approved. Wide working temperature range -From -4 F to 150 F (-20 C-+70C) Extemely cold and extremely hot weather will not effect its performance
7. Flexible Form Factor
   Small in size and light in weight 1/3 weight of Lead Acid and 65% weight of NIMH.
8. No Memory Effect
   The memory effect is when batteries gradually lose their maximum energy capacity if they are repeatedly recharged after being only partially discharged.
9. Fast Charge
   Can be fully charged in a very short time
10. Calculated Draw
    Works through the motor/controller for optimum efficiency

Lead Acid battery: Although lead acid is a widely used and relatively inexpensive technology, it has a poor cycle life and energy density, is unsuitably heavy, and extremely toxic.
Nickel Metal Hydride battery: This battery also has a relatively low energy density, decays faster under high temperature, suffers the memory effect, and is not suitable for high output usage.
Lithium Iron Phosphate Battery: Proven as the most environmentally friendly battery, it is the safest and most suitable for high output usage.

There are three types of lithium ion cells based on different cathode materials. They are lithium cobalt oxide, lithium manganese oxide and lithium iron phosphate types.

Lithium cobalt oxide cell has the advantage of high energy density, although it suffers from safety concerns due to unstable chemistry.
Lithium manganese oxide cell has been evaluated for the application on high rate due to the better safety characteristics. However, its high temperature performance is the major drawback.
Lithium iron phosphate cell has the best safety characteristics, long cycle life (up to 2000 cycles) and good availability. It is very suitable for high discharge rate occasions as needed for pedal assist or on-demand performance with a Minneapolis Electric Bicycle.
