Standard off-the-shelf battery

What Are Standard Battery Products?

Standard battery solutions from Large Power are pre-configured Li-ion packs available in widely used voltages and sizes. Unlike fully custom designs, these packs follow fixed form factors and integrate built-in protection features, making them more cost-effective and quicker to deploy. With stocked components and pre-validated designs, these solutions significantly reduce engineering efforts and development expenses. As a result, customers benefit from lower pricing and shorter lead times compared to bespoke battery builds. While streamlining the process, these packs still comply with industry safety standards, making them ideal for time-sensitive projects. As a trusted standard battery pack manufacturer and standard battery pack supplier, Large Power delivers reliable energy solutions tailored for efficiency and speed.

Product Categories

Large Power offers two main cell form factors in its standard product lineup: cylindrical and prismatic lithium-ion cells.

Cylindrical Cells
Our cylindrical cells include the popular 18650 and 21700 sizes. These cells have a standard tube-shaped metal casing that provides excellent protection and heat dissipation. For example, a typical 18650 cell (18×65mm) delivers about 2,300–3,600 mAh at ~3.7V, while the larger 21700 (21×70mm) cell offers 4,000–5,000 mAh. Cylindrical formats are highly cost-effective and consistent, making them well-suited for high-demand applications. Their uniform shape enables tight packing and efficient thermal management, which is why 18650/21700 packs power tools, e-bikes, flashlights, and other devices requiring durable, high-capacity batteries.

Prismatic Cells
Prismatic cells use a flat, rectangular metal casing to maximize space efficiency. This design stacks the internal electrodes tightly, yielding more energy per volume. Prismatic packs typically achieve 15–20% better space utilization than cylindrical cells, as the rectangular cells can be tiled without the gaps that occur with round shapes. Large Power’s prismatic batteries are stable and rugged (the rigid casing resists swelling), making them ideal for compact battery modules. They are commonly used where form factor and volume matter – for example, in battery packs for drones, solar energy storage units, and slim portable devices. The flat geometry also simplifies assembly and cooling, further benefiting high-capacity systems.
