Yes, you can mix different capacity lithium batteries, whether a normal 12V 100Ah battery or a Lithium server rack battery. . Here's a useful battery pack calculator for calculating the parameters of battery packs, including lithium-ion batteries. 2V; we need three cells in series to make a 12. In the figure above, the connections are indicated. With a 12V battery pack with 10Ah capacity, the calculator would determine how many 18650 cells to connect in series for voltage and in parallel for. . It's still a process that can be daunting for the first-time pack-builder though, because the other thing that most of us know about lithium ion batteries is that getting things wrong can cause fires.

Fortunately [Adam Bender] is on hand with an extremely comprehensive two-part guide to designing and building lithium-ion battery packs from cylindrical 18650 cells. (Edit 2025: re-linked through Internet Archive.) In one sense we think the two-parter is in the wrong order.
A typical 18650 battery pack for laptops has a nominal voltage of 11.1 V. This is achieved by connecting three 3.7V 18650 battery cells in series (3S).
To calculate the capacity of a lithium-ion battery pack, follow these steps: Determine the Capacity of Individual Cells: Each 18650 cell has a specific capacity, usually between 2,500mAh (2.5Ah) and 3,500mAh (3.5Ah). Identify the Parallel Configuration: Count the number of cells connected in parallel.
Let's calculate for a 11.1V 100Ah 18650 battery pack: 11.1V/3.7V=3 (S), 38.5 (P) cells. So, 3S38P would require 114 cells in total (3*38=114).
12V batteries are suitable for lighter, less demanding tasks, while 18V batteries offer more power and are better for heavy-duty work. . Not all lithium battery packs fit all tools. Compatibility largely depends on brand. You must match voltage, amp ratings, chemistry, size, and shape. It ensures optimal performance and safety in power tools. Always check compatibility before replacing or. . This guide will help you understand tool batteries and make the best choices to suit your needs. One System to Rule Them All: Sticking with a single brand's battery platform (like DeWalt's 20V MAX or Ryobi's. . Li-ion batteries are lightweight, have a high energy density, and last longer than other battery types, but they are more expensive.
