FAQs
Q: What is special about lithium batteries?
A: With high energy density, it reached 460-600Wh/kg, which is about 6-7 times that of lead-acid batteries. Long service life, the service life can reach more than 6 years. Light weight, the weight is about 1/5-6 of the lead-acid product under the same volume.
Q: What is a lithium battery used for?
A: Using lithium battery for power supply and storage. Like a backup power supply or a UPS. Reliable power for electric and recreational vehicles, golf cart, reliable and lightweight marine, solar energy storage, surveillance or alarm systems in remote locations.
Q: What is the difference between a lithium battery and a lithium-ion battery?
A: It mainly comes down to the fact that lithium-ion batteries are rechargeable, while lithium batteries are single-use. Lithium batteries have a higher energy density than lithium-ion batteries.
Q: Are your batteries safe?
A: Our batteries are safe. All Junlee batteries use the safest and most stable components, including a LiFePO4 cathode and an integrated Battery Management System (BMS). The BMS protects the cells against excessively high or low voltages, high currents, short circuits, and excessive heat or cold. .These are the most common causes of battery failures, and we have taken every precaution to mitigate these risks in all of our batteries.
Q: What are the advantages of lithium batteries?
A: Compared to lead-acid batteries and other lithium batteries, lithium iron phosphate batteries offer significant advantages, including better discharge and charge efficiency, longer cycle life, and the ability to deep cycle while now food. LifePO4 batteries often have a higher price, but a much better cost over the life of the product. No maintenance and a very long lifespan make it a worthwhile investment and a smart long-term solution.
Q: How do I choose the right deep cycle lithium battery for my application?
In most standard 12, 24, or 48 volt systems, the best lithium battery choice is LiFePO4 (lithium iron phosphate). The voltage of this type of battery is very similar to that of an AGM and will work great with readily available system components for your RV, boat, or off-grid power system.
