4000mAh

4000mAh lithium-ion batteries offer a balanced combination of capacity, size and current capability, particularly within larger cell formats such as 21700 batteries. This capacity is commonly used in applications that require reliable energy output, good thermal stability and consistent performance rather than maximum energy density.

At Elemex, our 4000mAh lithium-ion cells are genuine, carefully selected for safety, reliability and long cycle life. All products listed on this page share the same 4000mAh rated capacity, allowing straightforward comparison of compatible cells and configurations.
