Battery XCell 26650 Li‑Ion 3.7 V 5000 mAh single cell (MPN 150844)

XCell 26650 Li‑Ion single cell with a nominal voltage of 3.7 V and rated capacity of 5000 mAh. This rechargeable cylindrical cell is supplied individually and is designed for applications that require high energy density in the 26650 format. The cell chemistry and form factor make it suitable for use in larger battery packs, portable lighting, and devices where a balance of capacity and size is needed. Proper charging and protective circuitry are recommended to ensure safe operation and long service life.

Advantages

The XCell 26650 provides a high nominal capacity of 5000 mAh in a single cylindrical cell, enabling longer run times compared with smaller formats. Its Li‑Ion chemistry offers a favorable energy‑to‑weight ratio and relatively low self‑discharge. The robust 26650 housing supports repeated cycles and integration into assemblies where stable voltage and consistent capacity are required. The cell is suitable for both continuous and pulse discharge applications when used within specified limits.

Suitable for

• High‑capacity battery packs for e‑bikes and electric scooters
• High‑output flashlights and portable lighting systems
• Portable power tools with compatible 26650 cells
• DIY electronics projects and custom battery assemblies
• Power banks and backup power solutions requiring larger cell formats

Key specifications

• Cell type: rechargeable lithium‑ion (Li‑Ion) cylindrical cell
• Format: 26650 size
• Nominal voltage: 3.7 V
• Nominal capacity: 5000 mAh
• Configuration: single cell (supplied individually)

How to use

Install the cell according to device manufacturer instructions and observing correct polarity. Use a charger and charging profile suitable for Li‑Ion cells, maintaining recommended charge voltage and current limits. If assembling multiple cells into a pack, include a battery management system (BMS) or equivalent protective circuitry for cell balancing, overcharge, overdischarge and short‑circuit protection. Do not expose the cell to temperatures outside the device or charger specification and avoid mechanical damage to the casing.

Usage recommendations

For reliable performance, charge the cell with a dedicated Li‑Ion charger, avoid deep discharge below the recommended voltage, and store cells in a cool, dry place partially charged if not used for extended periods. When integrating into battery packs, follow industry best practices for wiring, fusing and thermal management to maintain safety and longevity.
