Looking to source 36V 18650 lithium battery packs for e-bikes, tools, or industrial devices? This guide covers configurations, performance specs, certification, and supplier evaluation for B2B buyers.
A 36V 18650 battery pack is a lithium-ion power system made by connecting ten 18650 cells in series (10S configuration). With a nominal voltage of 36V and a fully charged voltage of 42V, it’s widely used in electric bikes, scooters, power tools, and mobile equipment.
These packs offer a strong balance between energy density and output power, making them ideal for medium- to high-load devices where size and efficiency matter. Their standardized voltage also ensures compatibility with many off-the-shelf motors and controllers.
The cell is the core of every 36V battery pack, and choosing the right type directly impacts power output, runtime, safety, and lifespan. Most 36V packs use cylindrical 18650 cells, but not all 18650s are the same. B2B buyers need to balance between capacity, discharge rate, and reliability based on the end-use scenario.
Some cells are built for long runtime, offering higher capacity but lower current output. Others are optimized for high-power delivery, with lower capacity but stronger discharge performance. Below is a comparison of typical 18650 cell types used in 36V packs:
| Cell Type | Typical Capacity | Max Continuous Discharge | Best For |
|---|---|---|---|
| High-Capacity Cells | 3000–3500mAh | 5A – 10A | Long runtime, light-load devices (e.g. monitoring, diagnostics) |
| High-Drain Cells | 2500–2800mAh | 15A – 30A | High-power tools, scooters, e-bikes under load |
| Balanced Cells | 2600–3000mAh | 10A – 20A | General-purpose devices with mixed performance needs |
For critical systems, always confirm that cells are Grade A, matched for voltage and resistance, and come from trusted brands like Samsung, LG, Molicel, or verified domestic suppliers. Request test reports and verify the BMS is properly rated to support the selected cells.
Most 36V 18650 battery packs use a 10-series (10S) configuration to deliver a nominal voltage of 36V (3.6V × 10 cells). To increase capacity, cells are connected in parallel (P). For example, a 10S3P pack uses 30 cells (10 in series × 3 in parallel).
Different configurations offer different levels of energy storage and output current. Here’s a comparison of the most common setups:
