• Over 10 Years Service Life >4000 Cycles: In order to achieve a stable power supply even under heavy load, lithium batteries are definitely the best alternative to lead-acid batteries. Hypery lithium iron phosphate is able to be recycled for up to 4000 times. The service life can reach to over 10 years typically.

• Smaller Size and Lighter Weight:It's only 1/3 of the weight of a lead-acid battery, easy to move and install. It is an ideal choice for outdoor camping power supply and simple indoor installation.  

• No Memory Effect:LifePO4 Battery does not have memory effect, even if they are not fully charged or discharged for a long time, they won't leave traces and reduce the battery capacity. 

• High Speed Charge and Discharge: High charging and discharging rapidly charging and discharging are possible.

• High Energy Density:Greater capacity, smaller weight and volume.

• Environmental Protection:Lead-free, acid-free.

• Wide application: LiFePo4 lithium battery is more safe, efficient and portable, which is suitable for mobile homes, caravans, ships, golf carts, tool trailers, solar panels, children's vehicles or can be used as emergency power supplies.

• The Smart Battery Management System(BMS): The Smart Battery Management System(BMS) provides comprehensive protection for the battery and intelligently managers the charge/discharge process. It can protect it from overcharge, deep discharge, overload, overheat, short circuit, and low self-discharge rate.  

• Warranty:5-year warranty is provided and 24/7 technical support team is available.

Frequently Asked Questions:                                                                                                      

• About BMS(Battery Management system)--The battery management system monitors and controls each unit of the battery to ensure the battery shuts down in the event if undervoltage or overload, and restarts automatically once the problem is resolved to avoid being damaged. Important functions of the BMS:

         Overcharge protection: When overcharging occurs, the BMS will turn off the battery output to protect the battery. The battery has no voltage at this time; When the condition returns to normal, the battery will automatically return to normal.

         Discharge protection: Each cell in the battery individually monitors the battery discharge. If this turns off the battery output, the only way to turn the battery back on is to charge it.

         Overvoltage protection: The total charging voltage of the LiFePO4 battery is 14.6V(the charging voltage of a single cell must not exceed 3.65V/cell). Therefore, it is the best to use a suitable charger with a final charging voltage of 14.4V to 14.6V to charge the LiFePO4 battery.

         Active Balancer: The built-in active balancer can adjust the battery at any time to ensure the internal small batteries(cells) have the same voltage and prolong battery life.

         Charge Control: BMS always monitors and controls all parameters for reliable and safe charging. If something goes wrong, you can prevent charging by turning off the battery output to protect the battery.

 

        Battery Temperature Protection:When the battery temperature is too high/low, the BMS will turn off the battery. At this time, you need  to wait for the temperature return to normal first, and then BMS will enable the output again.

• Can batteries be connected in series and parallel?-- Yes, please note that batteries of the same brand and capacity can be used in series and parallel connection. Please ensure that the batteries are charged to the same voltage before using them in series and parallel connection.

• How to place the battery?--The lithium battery is free from lead-acid battery safety issues such as battery leakage and battery corrosion, so you can place it in any positions with cool and try conditions, please do not expose it to high temperatures or direct sunlight. Please remember to keep it dry and clean after every use.

• Is it pre-charged? Is there any possible to used it once after received it?--Yes, the batteries were pre-charged before shipment, which can guarantee your basic usage under the urgent ondition. But due to the safety of transportation, the pre-charged capacity won't exceed 50%.

General Warnings:                                                                                                                  

• Do not short-circuit the positive and negative terminals of the battery.
• Please keep the battery away from water, heat, sparks and harmful chemicals.
• Do not expose the battery to high temperatures or direct sunlight.
• Do not puncture, drop, squeeze, incinerate, shake or hit the battery.
• Do not disassemble or assemble the battery.
