Key Features of the PKNERGY 25.6V Solar Battery
The PKNERGY 25.6v 200ah Lifepo4 Battery features an extremely safe and stable chemistry, with PCB and/or BMS built inside to balance and protect the battery. Which really catch the eye as a flexible and effective option. They bring perks like high energy density, a long cycle life, and not needing much upkeep. It offers a long life-cycle and can be circularly used up to 6000 times, which is eight times more than a lead-acid battery. Moreover, the battery is lighter, with the best power-to-weight ratio of 1/3 of a lead-acid battery’s weight. The battery also offers good performance at high temperatures and has high temperature resistance. With a low self-discharge rate of less than 3% monthly, the battery has no memory effects and highly efficient charge. The environmentally friendly battery is clean and green energy, posing no pollution on our environment. These features make them best batteries for solar off-grid setups, guaranteeing a fulfilling and independent energy journey.
Performance And Test Conditions of the PKNERGY 25.6V Solar Battery
Using the technology of lithium iron phosphate cell, the PKNERGY 12v 100ah Lifepo4 Battery offers superior safety, thousands of cycles, 100%DOD, under normal conditions. It has built-in automatic protection for over-charge, over-discharge, over-current, and over-temperature and is free of maintenance. The battery features internal cell balancing and is of a lighter weight, about 40%~50% of the weight of a comparable lead-acid battery. It is a replacement for a lead-acid battery and has a wider temperature range of -20℃~60℃. It supports series application expansion (up to 25.6V) or two in parallel.

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.
