Lithium Ion Battery Benifits

Charges 4-6x Faster

No more waiting for 6-12 hours to get a full charge. Our Ionic lithium solar batteries charge 4-6 times faster than lead acid.

Lasts 2-4x Longer

We build our batteries tough, guaranteeing 2 to 4 times the lifespan of lead acid.


Lithium solar batteries are a dream come true for renewable energy enthusiasts. They’re safe, lead-free, and recyclable.

Maintenance Free

Unlike their attention-hungry lead acid counterparts, these batteries need absolutely no maintenance.

15x Lower Discharge Rate

Lithium solar batteries discharge at a rate of just 2% per month.

Up To 70% Lighter

Same storage capacity as comparable lead acid batteries. Less than half the weight.

Drop In Replacement

It’s easy to switch to lithium batteries for solar setups.

Run In Parallel

Connect and run as many solar lithium batteries as need in your solar setup.



Q:What is special about lithium batteries?

A: With high energy density, it has reached 460-600Wh/kg, which is about 6-7 times that of lead-acid batteries. Long service life, life span 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:Lithium battery use for power and energy storage. Like emergency power backup or UPS. Dependable electric and recreational vehicle power, golf cart,reliable and light-weight marine,solar power storage, surveillance or alarm systems in remote locations.

Q:What is the difference between a lithium battery and a lithium-ion battery?
A:It mostly comes down to the fact that lithium-ion batteries are rechargeable while lithium batteries are single-use. Lithium battery 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 a built-in 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 is an advantages of lithium batteries?
A:Compared to lead-acid and other lithium batteries, lithium iron phosphate batteries offer significant advantages, including improved discharge and charge efficiency, longer life span and the ability to deep cycle while maintaining power LifePO4 batteries often come with a higher price tag, but a much better cost over the life of the product. No maintenance and super long life make them a worthwhile investment and a smart long-term solution.

Q:How do I choose the correct lithium deep cycle battery for my application?
In most standard 12, 24, or 48 volt systems the best choice of lithium battery is LiFePO4 (Lithium Iron Phosphate). The voltage of this type of battery is very similar to an AGM and will work great with readily available system components for your RV, boat, or off-grid power system.
