Molicel Li-Ion Cells and Packs
High-drain lithium ion cells have become a popular choice for applications that demand strong current delivery, and this category collects Molicel ultra-high power cells and assembled packs. The listings cover both loose single cells and packs built up for higher voltage.
21700 and 18650 Formats
The Molicel INR21700-P45B is a 4500mAh cell in the larger 21700 size, offered as a single cell, a 2S two-cell pack, and a multi-cell custom pack built in parallel for greater capacity. The smaller INR18650-P28A is a 2800mAh cell in the common 18650 format, available as a single cell, a 2S pack, and a multi-cell pack.
Choosing between the two formats usually comes down to the capacity and physical size your project can accommodate, since the 21700 carries more energy while the 18650 fits tighter spaces. Builders working with these high-drain cells often solder their own packs or order a pre-built pack to save the assembly work.
Review the single cells and assembled packs above to match your build.
