Battery pack ANSMANN 2S2P 4×18650 Li‑Ion 7.2V 6700mAh

The ANSMANN Battery pack 2S2P 4×18650 Li‑Ion 7.2V 6700mAh is a rechargeable power source assembled from four 18650 Li‑Ion cells in a 2-series, 2-parallel configuration. It provides a nominal voltage of 7.2 V and a usable capacity of 6700 mAh, delivering stable current for a wide range of portable and stationary applications. The pack is designed as a direct replacement or upgrade for devices that require a compact high-capacity 7.2 V supply and benefits from the energy density and cycle life typical of lithium‑ion technology.

Advantages

The battery pack combines multiple 18650 cells to offer higher capacity while keeping the overall size compatible with many battery compartments. Its 2S2P arrangement balances voltage and capacity to meet devices needing 7.2 V while extending runtime compared with single-cell solutions. Rechargeable Li‑Ion chemistry ensures lower self-discharge and higher energy density compared with older NiMH or NiCd alternatives. The pack is intended for safe, repeated charging when used with suitable chargers and charging procedures.

Suitable for

• Portable equipment requiring 7.2 V nominal supply
• Hobby electronics, RC transmitters, and models
• Backup power for small devices and sensors
• Replacement battery for compatible tools and instruments

How to use

Install the battery pack into the device battery compartment or connect using the device’s compatible connector, observing correct polarity. Use a charger compatible with 7.2 V Li‑Ion packs and follow the charger manufacturer’s instructions. Charge the pack fully before first use and avoid deep discharges below the device’s recommended cutoff to maximize cycle life. Inspect the pack for damage before each use and do not use if the housing is deformed or cells appear swollen.

Usage recommendations

Store the battery pack at moderate charge (about 30–50%) in a cool, dry place when not in use for extended periods. Avoid exposure to high temperatures, direct sunlight, or moisture. Only use chargers and equipment rated for lithium‑ion batteries and follow safety guidelines to reduce the risk of thermal events. Dispose of the pack according to local regulations for rechargeable batteries.
