36V Lithium-ion Battery Pack

UFO Lithium Battery is lightweight and compact in size, which makes it ideal for limited space use. It is easy to carry than traditional batteries like lead-acid batteries that is 3 times weight of lithium batteries. With the feature of longer cycle life, it helps to minimize battery replacement cost.

The Advantages of Lithium-ion Battery Pack

1.Higher energy density

The higher energy density of lithium-ion battery pack means we are going to get more power out of the same physical size cell than we could get from a lead-acid battery. So when using lithium-ion battery for electronic gear, it means more runtime but less weight.

2.Less weight

Less weight could be a big advantage for most electronic applications that need to be in a compact size and lightweight for use, including mobile applications, robots, drones, floor scrubbers, RVs. A lot of power is used for those devices, so less weight would be certainly an advantage for mobile applications.

3.Thousands VS hundreds of cycles

More cycles are an advantage by a lithium product we`re gonna get. You know the lithium batteries could provide thousands of cycles versus lead-acid batteries which only offer hundreds of cycles. It is a big difference in the cycling ability of lithium over lead-acid batteries.

4.Charge and discharge rate

We are able to discharge a lithium product much quicker than that of a lead-acid product and get the same capacity. If the lithium-ion battery pack is discharged to 80%, you can still get a good lifespan. But doing that with a lead-acid battery will damage its lifespan. Generally, a lead-acid battery can only use fifty percent of the discharge. The recharge time is quicker on a lithium product as well especially if we have a charger that`s large enough to put the capacity back. The lithium-ion battery packs have a low self-discharge rate of only 1-2% per month.


5. Less Maintenance

When using lead-acid batteries for power supply, regular maintenance is essential to ensure the battery performance. However, when purchasing lithium-ion batteries for power use, less maintenance is required. The lithium-ion cells is more stable with good performance. It saves a lot of time for maintenance and cost for replacement.
