👍10 year lifespan
Lithium iron phosphate battery is recycled more than 3000 times, which is more than eight times that of lead-acid batteries (300-400 times). The service life can reach 10 years under ideal conditions.

👍Light and Clean Energy
The weight of lithium battery is 1/3 that of lead-acid battery. It is easy to carry and install. The attribute of "harmless and clean energy for the environment" definitely makes it an ideal replacement for most of the conventional ones Lead-Acid Cycle Batteries.

👍High Security with BMS
Our BMS is a multi-channel battery monitoring and balancing system for LiFePO4 battery packs.
Battery has built-in BMS (battery management system), low self-discharge, can prevent overcharge, over-discharge, over-current, overload, short circuit.

👍Wide range of uses
The LiFePo4 lithium battery is safe, efficient and portable, suitable for RV, caravan, electric boat, golf cart, children's vehicle, tool trailer, solar panel, or can be used as backup power.[Caution]This battery is not suitable for motorcycles or starter batteries

👍Warranty and delivery time
5-year warranty, 24-hour response to customer questions. 
Fast delivery takes 2-4 working days in England and 3-7 working days in the Europe.

♻️ Battery Management System (BMS)                                                                                 

The battery management system monitors and controls each unit of the battery to ensure the battery shut down in the event of under voltage or overload, and restarts automaticlly once the problem isresolved to avoid damaging the battery. lmportant functions ofthe battery managementsystem:

✔️ Overcharge Protection
When over charging occurs, the BMS will turn off the battery out put to protec 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
Eachcell in the battery individuall monitors the battery discharge. If this tums off the battery output,the only way to tum the battery backon is to charge it. Note: Even small consumer such as alam systems,relays, backup systems et.consume capacty and drain the battery. If you don't use the battery for along time, please disconnect all connections between the battery and the system.

✔️Overvoltage Protection
The total charging voltage of the LifePO4 battery is14.(the charging voltage of a single cell must not exceed 3.65V/cell, otherwise,the battery will be damaged by overvoltage.Therefore,it is best to use a suitable charger with a final charging voltage of 14.4V to 14.6V to charge the LiFePO4 battery.Athough BMS can protec the battery from overcharging, it needs to absorb and burn electicity by itself. If the charging voltage exceeds14.6V for a long time,it wil damage the BMS!

✔️Active Balaner
The buili-inactive balancer can adjust the battery at any time to ensure the intemal small batteries(cells) have the same voltage and prolong battry life.

✔️Charge Control
BMS always monitors and control all parameters for reliable and safe charging.If something goes wrong you can prevent charging by tuming 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 to retun to normal first,and then BMS will enable the output again.

🔋 Warming Tips                                                                                                                         

  • Do not short-circuit the positive and negative terminals of the battery.
  • Please check the routing circuitry to ensure the adapter and connector class are correct..Please keep the battery away from water, heat, sparks and harmful chemicals.
  • Do not immerse the bag in water or throw into fire.
  • Do not expose the packaging to high temperatures or direct sunlight.
  • Do not puncture,drop, squeeze, incinerate, puncture, shake, or hit the battery.
  • Put the battery in a cool and dry place. If stored for more than three months, please charge 80% before use. The battery should be charged every 3 months.
  • Do not disassemble or assemble the battery.

🔋 Questions                                                                                                                                 

1. Can this battery be charged with a lead-acid battery charger?

We recommend our customers to use a professional LiFePO4 charger for charging. A lead-acid charger cannot fully charge a LiFePO4 battery.

2. Can these LiFePO4 batteries be connected in parallel or in series?

Theoretically yes, but you must ensure that the batteries are fully charged and all have the same voltage level before using them in series or parallel. We do not recommend mixing series and parallel.

3. what should I do if the battery is not charged and cannot be used?

Our battery BMS has several protection functions to ensure safety: short circuit protection, overcurrent protection, overload protection, overvoltage protection, overcharge protection and overdischarge protection. Once a protection has been triggered, the battery is temporarily unusable.
