Elgato EVE INR18650/33V Li-ion Battery 18650 Flat-Top 3200 mAh 3.6 V

The Elgato EVE INR18650/33V is a rechargeable 18650-format lithium‑ion cell with a flat-top terminal, a nominal voltage of 3.6 V and a rated capacity of 3200 mAh. Engineered for high-drain applications, this cell provides consistent voltage under load and a compact cylindrical form factor suitable for single-cell devices or multi-cell battery assemblies.

Advantages

This Li-ion cell offers high energy density and stable discharge characteristics that suit devices requiring sustained current delivery. Its flat-top terminal simplifies mechanical integration into battery packs and DIY assemblies. The 18650 format is widely supported by holders and chargers, and the cell’s rated capacity gives a balance between runtime and physical size for portable power applications.

Suitable for

• High-drain flashlights and portable lighting
• Power tools and cordless appliances requiring sustained current
• E-bike modules and small electric mobility devices when used in appropriate packs
• DIY battery packs, custom power banks and experimental electronics projects

When it may not be suitable

This cell is not intended as a drop-in replacement in devices that require protected cells, specialized end terminals, or proprietary battery shapes. Use caution where integrated battery-management, overcurrent protection, or physical retention features are mandatory; in such cases, a protected cell or complete battery pack with the necessary safety circuitry is more appropriate.

Key specifications

• Cell type: Lithium‑ion (INR chemistry)
• Format: 18650 cylindrical cell, flat-top terminal
• Nominal voltage: 3.6 V
• Rated capacity: 3200 mAh
• Designed for high-drain discharge profiles

How to use

Charge the cell with a charger compatible with lithium‑ion chemistry and the 18650 format, following the charger manufacturer’s instructions. Install cells in holders or battery assemblies observing correct polarity and secure mechanical retention to prevent short circuits. For multi-cell configurations, ensure matched cells and appropriate battery-management circuitry to balance charge and protect against overcharge, over-discharge, and excessive current.

What to consider before purchase

• Confirm that a flat-top 18650 cell fits the device or holder you intend to use.
• Verify whether your application requires protected cells or built-in safety circuitry.
• Ensure your charger supports lithium‑ion chemistry and the cell’s voltage specifications.
• Plan for proper thermal management and safe current limits in high-drain applications.

Usage recommendations

Store and transport cells in non-conductive holders, avoid shorting terminals, and follow local regulations for battery handling and disposal. For extended service life, avoid deep discharges and high-temperature environments; charge and store cells at moderate states of charge when not in use.
