Poor contact can be divided into two categories, one is contact element (such as potentiometer) contact oxidation or wear; the other is virtual welding, including solder joints are not welded, or solder joints are high-power components, When the current is large, the solder aging causes the solder joint to crack and malfunction. Most of the faults with poor contact belong to the latter category. In the actual maintenance, a set of simple and quick methods for finding the virtual solder joints is summarized and introduced to everyone for reference. There is a slight blackening crack around the foot of the solder joint component. The crack becomes more and more obvious with the frequent occurrence of the fault. The heavy component can be loose, and the light is like a welded stone. The crack indicates that the solder joint has overheated and melted, and it will be delayed sooner or later. My approach is to carefully check all the black-spotted solder joints, especially the high-power devices, regardless of the fault, and find that the cracked solder joints are soldered. This step is familiar with the solder joint crack characteristics. Ten minutes is enough, and you can often get twice the result with half the effort.
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.
