advantages of our lifepo4 batteries
1: Safety: LifePO4 is the safest battery in the world till now, which does not burning with over 30V discharge voltage and it does not explore when you puncture the battery. We have achieved CE and UL certifications.(This photo is waterproof testing,goldfish is still safety there)

2: Environments friendly: We attained RoHS certification which proved the batteries are not contained toxic material.
3: Powerful: Discharge with 10C, battery's temperature does not exceed 65C.
4: Long cycle life: After 2000 times charge and discharge, the capacity remain 80% of the original one.
5: Temperature extension: In the scope of -20~70the batteries can be normally used.
6: Lower average price per year:The average price per year is 100 Yuan RMB less than the lead-acid battery for 5 years.
7: Small in volume and light in weight:The iron-lithium battery is about 1/2 the volume and 1/3 the weight of the lead-acid battery. Thus the performance of the whole bike is improved and the battery can be taken off easily.
8: Intelligent charge system: voltage of each cell can be detected, each cell can be protected against overcharge, overvoltage, short circuit andoverheat, and so that battery can be charged balance.
9: Patented and beautiful appearanceThe appearance designed by patent can be integrated with the hole bike.
