Features

1. No memory effect. Lithium ion batteries do not have the so-called memory effect of nickel cadmium batteries, so do not discharge them before charging them, as nickel cadmium batteries do. It can also be charged at any time, regardless of the battery power.
2. Long service life. Under normal working conditions, it can generally be fully charged and discharged for more than 3000 times.
3. Lithium ion batteries have strong adaptability to high and low temperatures. It can be used in an environment of - 10 ℃ to 40 ℃. However, as far as possible, to prevent charging in high temperature environments, excessive temperatures can exacerbate battery loss and shorten battery life.

4. Green and environmental protection. Due to the fact that batteries do not contain heavy metal elements such as cadmium, lead, and mercury, there will be no environmental pollution during use and production, and they can be safely used.
5. High storage energy density and lighter weight. The storage energy of lithium ion batteries has currently reached 460-600Wh/kg, about 6-7 times that of lead acid batteries. The weight of lead acid in the same volume is only 1/5 of that of lead acid.
6. Small self discharge can be stored for a long time.

FQA

 

1. How long will a 200Ah lithium battery last?
If you have a 200ah battery, it can supply 20 continuous amps for 10 hours or 10 amps for over 20 hours. The term voltage in a battery refers to the difference in electric potential between the positive and negative terminals of a battery.

 

2. Is 12.8 V same as 12V?
Although it is 12V (12.8V nominal) battery, the LiFePO4 battery is using different technology from the conventional battery (Lead acid).

 

3. How do I know if my lithium-ion battery is still good?
Therefore, you can check the battery with a voltmeter or multimeter to know if it's dead or not. It is wise to replace the battery once you notice that the voltage is lower than the one listed on the battery by the manufacturer.

 

4. How long does a 2.58 kWh lithium battery last?
2.58kWh battery means you can run 2580W (2.58kW) of power for an hour. You can run 1.29kW of power for 2 hours.
