Generic 21700 Flat-Top Rechargeable Li-ion Battery 3.7V 4000mAh Each (4 Pack)

Product description

This set includes 4 pieces of 21700 flat-top rechargeable Li-ion batteries, each rated at 4000mAh with a nominal voltage of 3.7V, providing a total combined capacity of 16,000mAh.

Designed for applications that demand stable power output and extended runtime, these lithium cells deliver consistent energy performance across repeated charge and discharge cycles.

The 21700 format offers higher energy density compared to standard 18650 cells, allowing devices to operate longer while reducing the need for frequent recharging.

The flat-top terminal design ensures compatibility with systems that require non-protruding positive contacts, making these batteries suitable for custom battery packs, robotics platforms, power tools, automation systems, and energy storage assemblies.

Uniform cell height and consistent dimensions support reliable series or parallel configurations, helping system integrators maintain stable electrical connections and predictable performance.

Manufactured using IMR lithium chemistry, these rechargeable cells provide low internal resistance, stable current delivery, and improved thermal stability when used with proper charging equipment and protection circuits.

Clear labeling on each cell indicates voltage, capacity, watt-hour rating, and polarity for easier identification and safer integration into professional and technical systems.

This battery pack is intended for experienced users, engineers, and system builders who understand lithium battery handling and safety requirements.

For optimal performance and longevity, the use of compatible chargers and battery management systems (BMS) is strongly recommended.

When installed correctly, this 4-pack 21700 lithium battery set offers a reliable, high-capacity power solution for long-term technical, industrial, and educational applications.
