Lithium Battery Packs: Choosing the Protection Board Best for You

Written by Anton Beck
Posted on May 31, 2023 at 8:51 AM

Lithium batteries contain high density which is ideal when powering electronics and applications that require a large amount of power over an extended time. However, the battery chemistry is unstable. These batteries can experience overcharging, over-discharging, and discharging that occurs too fast. When the following actions occur, the battery can become damaged, have a diminished lifespan, or even create a safety hazard.

External Battery Storage: The Chemistry and the State of Charge

Written by Anton Beck
Posted on May 15, 2023 at 8:33 AM

Companies and individuals may store batteries outside the device as backup power when there is a power failure, or when storing extra battery packs. Another reason to store external batteries is when the device won't be used often as the device may drain the battery even when turned off due to internal monitoring systems.

Etch Compensation: What it Means for Your PCB Data

Written by NetVia Group
Posted on April 26, 2023 at 8:58 AM

Etch compensation is a process used in the design of printed circuit boards (PCBs) to adjust the trace widths to compensate for any changes that occur during the PCB manufacturing process. When PCBs are manufactured, the etching process used to create the copper traces on the board can cause some amount of variation in the width of the traces. This variation can be caused by factors such as the thickness of the copper, the quality of the etching process, and the chemical composition of the etchant.

Pros and Cons of Lithium Prismatic Cells vs Cylindrical Cells

Written by Anton Beck
Posted on April 13, 2023 at 8:49 AM

Due to the vast shapes of electronics and other applications that function on battery power, battery cells also come in different shapes to fit the application. Two common types of shapes are prismatic cells and cylindrical cells. Both offer specific qualities to the application, whether you are looking for cost-effective batteries that are easy to mass produce or batteries with a higher capacity range.

What is UN38.3 Testing and Why is it Necessary?

Written by Anton Beck
Posted on April 5, 2023 at 9:11 AM

Battery chemistries that are lithium-based must undergo UN38.3 testing requirements before being transported. This testing certifies that the batteries are safe and will not pose a safety risk during shipping over air, water, rail, or road transportation methods.
