Technical FAQs 4

What are power tool batteries?

Power tool batteries have come a long way from bulky nickel-cadmium (NiCd) packs. Today, lithium-ion (Li-ion) technology dominates the market, offering greater power, longer runtimes, and lighter weights. This guide dives into the world of power tool batteries, exploring different chemistries, voltage platforms, amp-ho

How do I choose a lithium battery?

Choosing the right cell type and configuration ensures the battery delivers optimal performance and longevity. When designing or purchasing a lithium battery, consider: Application Type: Starter, cyclic, or high-rate discharge. Size Constraints: Ensure the battery fits the intended device.

How do you build a lithium battery?

When building a lithium battery, first select the cell type, then determine the required amp-hours, voltage, and amperage. For example, a 25 AH 3.2 V prismatic cell can form a 125 AH 12.8 V battery in a 4S5P configuration, where parallel connections boost capacity and series connections increase voltage.

What are the components of a lithium battery pack?

When you examine a lithium battery pack, the most noticeable components are the individual cells and the circuit board. Lithium batteries are commonly built using three main types of cells: cylindrical, prismatic, and pouch cells. Each type offers unique advantages, depending on the application.
