Before Purchase
We understand the importance of maintaining the consistency of each cell in the battery pack, so we match and balance all cells to ensure that the internal resistance, voltage and capacity of the cells are fully matched and balanced before shipment. This process is very necessary.In case you find that the cells are not fully balanced when you receive the goods, you can contact us for related help.
Yes, we ship the battery with the Busbars connector and screws. Of course you can also contact us for solderless LiFePO4 batteries.
After receiving the battery, please immediately check whether the insulating layer of the battery (usually a blue film) is damaged and whether the QR code is scratched. Also use a multimeter to check the voltage/internal resistance/capacity. Be sure to charge the battery to full voltage before using it for the first time.
Typical estimated lifetimes for LiFePO4 batteries are 5-15 years or 4000 to 8000 charge cycles. A charge cycle is a cycle of use from full charge to full discharge to full charge.
● Grade A: Cells perform to manufacturer specifications.
● Grade B: Cells under-perform or have other defects.
● Grade C: Cells are used, repackaged, salvaged, or damaged.
Batteries
Larger monomer capacity.
Higher stability.
Higher security.
Higher space utilization.
There is no doubt that LiFePO4 batteries are one of the safest lithium-ion batteries out there. Due to its chemical properties and safe internal structure, LiFePO4 batteries will not explode even if they are severely damaged (such as puncture/strong knocks).
Need to do this. Compressing the battery helps maintain battery performance and can improve battery life. What's more, battery compression avoids battery bulging.
It is best not to mix batteries of different brands, because there may be subtle differences;
It is also best not to mix batteries with different degrees of old and new, because the weakest battery in the battery pack will restrict the performance of the entire battery pack;
Never mix batteries of different chemical properties, this may kill your LiFePO4 battery, although there are ways to achieve it, it is definitely not recommended for battery beginners to consider;
Batteries with different capacities can be mixed, but the premise is that both batteries are 3.2V and connected in parallel.
The most important thing is the temperature. LiFePO4 batteries are well stored at room temperature (15°C~25°C), but too low temperature may damage the battery. In an icy environment, you need to pay attention to the insulation of the battery. Alternatively, the battery can be stored in a dry and ventilated room at 50% SOC.
The reasons for the expansion of LiFePO4 batteries include abuses such as overcharging and overdischarging; environmental reasons such as high temperature, high humidity, and ultra-low pressure; and production process reasons.

Battery BMS / Balancer
Can not. BMS is an important component to ensure battery performance and safety. Without the support of BMS, LiFePO4 batteries may be overcharged/overdischarged, which will cause battery damage.
A battery management system (BMS) is a device that manages a rechargeable battery (battery or battery pack). It can monitor the state of the battery to obtain calculation data to protect the battery. For example, it can prevent the battery from overcharging/overdischarging/overcurrent, and it can also provide battery balancing to a certain extent. The BMS can monitor the battery status represented by various items.
1.Voltage: The total voltage, or the voltage of a single cell.
2.Temperature: The average temperature, or the temperature of a single cell.
3.State of Charge (SOC) or Depth of Discharge (DOD): Indicates the charge level of the battery.
4.State of Health (SOH), various defined measures of the overall condition of the battery.
5.Current: The current flowing into or out of the battery BatteryFinds has its own factory to design and manufacture high quality BMS for all types of Lithium battery packs.
We test each BMS before shipping and promise that the BMS is fully functional and secure.
As a device to ensure battery safety, BMS must have high safety level.
The balancer is an important accessory in the battery pack. The balancer can balance the charge of each cell in the battery pack for a long time, ensuring that the battery pack can maintain performance for a long time. If you don't use a balancer, you need to rebalance every once in a while, which will consume a lot of your time.
Recycle
Yes, LiFePO4 batteries are recyclable. LiFePO4 batteries contain things like copper, cobalt, and nickel, as well as rare earth, of which up to 96 percent of them can be recovered. So By recycling, we can reuse these materials less stress is put on the environment.
1. Conserve the non-renewable resources
2. Lower manufacturing costs
3. Reduce the quantity of material going into landfills
4. Less of the associated environmental harm
5. Avoid Potential Fire Hazard 6. Create new jobs
First tape all LiFePO4 battery terminals to prevent them from discharging power. Then put them in the nearest battery recycling bin. Or you can go to an electronics hardware store/battery recycler for help.
Earth 911 database and Call2Recycle to find battery recycling drop-off centers near you.
LiFePO4（LFP）Batteries and Other Batteries
LFP batteries and NMC batteries are both lithium-ion batteries, but the chemical properties are somewhat different.
LFP battery: The nominal voltage of the single unit is 3.2V, high safety and many cycles. The energy density is slightly weaker, suitable for energy storage projects and DIY projects.
NMC battery: The nominal voltage of the single unit is 3.7V, the safety is slightly weaker and the number of cycles is relatively small. High energy density, suitable for use as power batteries (such as electric vehicles).
LFP batteries are lithium-ion batteries, while AGM batteries are lead-acid batteries. The difference between the two is huge.
LFP battery: The nominal voltage of the single unit is 3.2V, with high safety and many cycles. Higher energy density than AGM batteries, suitable for energy storage projects and DIY projects. To a large extent, it is an upgrade of the AGM battery.
AGM battery: The nominal voltage of the single unit is 2.1V, the safety is general and the number of cycles is small. It has low energy density and is also suitable for energy storage projects. The advantage is that it is very cheap and can be bought everywhere.
