PKNERGY 12.8V 6Ah LiFePO4 Replacing Lead Acid Battery
PKNERGY Lithium Iron Phosphate ( LiFePO4 ) batteries are developed to deliver high efficiency energy output compared to equivalent lead acid batteries. They are able to accept continuous high rate charging amps which make the battery fully charged in short time and improve the load service efficiency significantly. The built-in advanced BMS ensures intelligent automatic protection against over voltage, over current, over discharge, over temperature.
Features:
A. Extremely safe and stable chemistry: PCB and/or BMS built inside to balance protect the battery.
B. Long life-cycle: Can be circularly used, best can up to 6000 times recycles , 8 times of Lead acid battery.
C. Lighter weight, with the best power-to-weight ratio: 1/3 of Lead acid battery weight.
D. Good performance at high temperature and high temperature resistance
E. Low self-discharge rate, less than 3% monthly.
F. No memory effects and highly efficient charge.
G. Environment friendly: Clean and Green energy poses no pollution on our environment.

Testing Instruction | Requirement |
| 1 | Over- charge test | Charge in accordance with the following two ways ( Choosing one between the two). (1 ) Charge at 1 Ccurrent for 9 0 min or until voltage of some single battery reaches 5 . 0 V ( stop test when fulfills eithercondition). ( 2 ) Charge at 3 C current until the voltage of some single battery reaches 10 . 0 V, then stop the test. | The battery shall not explode or catch fire |
| 2 | Over- discharge test | Charge the battery. Place at 20±5℃ for 1h, then discharge in 1 / 3 C current at same emperature until some cell’ s voltage is 0 V | The battery shall not explode orcatch fire |
| 3 | Short- ircuiting Test |
After charge batteries, place at 20 ± 5 ℃ for 1 h. Short the battery for 1 0 min, the external circuit resistance should be less than 5 mΩ.
