The LiFePO4 battery is a kind of rechargeable battery using lithium iron phosphate as the cathode material, which thakes the advantages in the security of battery management system and service life in deep cycles. Why Choose the LiFePO4 battery? It shares the advantage of high capacity and long service life with smaller size and lighter weight which can satisfy the needs of energy storage well.

It is structurally stable and has good thermal stability and cycle performance. No matter the condition of the battery is, it can be used at any time. It does not need to be fully discharged before charging. It charges 2-3 times faster than the traditional SLA batteries, which will help you save time and balance life rhythm. It contains no toxic heavy metals which will not be a burden to environmental protection. The product is over 3000 times cycles which is much more than normal batteries so stays a long-term life, that typically up to 7-8 years.

The battery management system will cut off the current output to protect the battery from overcharges, overdischarges, overloads, abnormal temperatures and short circuits, which can improve the performance of battery. Sturdy ABS surface texture and IP65 of waterproof level make it much safer to use; M5 type terminal takes a high conductivity when connecting. The battery has been tested well under various of conditions. Even in the low temperature (0°C) and high temperature test (>55°C), neither the current nor the voltage were hardly affected. The product is much more stable in performance so it can be widely used in campers, caravans, camping, boat, exterior lighting, car start temporarily, caravan mover, off-grid, and other areas where need power supplies.

There are two charging ways usually: charger and solar panel. It is best to use a suitable charger with a final charging voltage of 14.4V to 14.6V to charge it.

Although BMS can protect the battery from overcharging, it needs to absorb and burn electricty by itself. If the charging voltage exceeds 14.6V for along time, it will damage the BMS. It is very demanding for all the LiFePO4 batteries on the market to be connected in series or parallel. It needs to make sure the voltage of every battery is almost the same under the condition of which the functions of the batteries are all standardly normal.

If you want to, please make sure you are professional enough to judge and handle the using conditions and methods. Please put the battery in a cool and dry place. If it is stored for more than three months, please charge it to 80% before use. The battery should be charged every 3 months to keep the cells alive.
