Rechargeable Li‑Ion Battery Pack ANSMANN 1S3P 3×18650 3.6V 10050mAh with Cable (MPN 2447-3034-40)

ANSMANN rechargeable Li‑Ion battery pack configured as 1S3P combines three 18650 cells to deliver a nominal voltage of 3.6 V and a total capacity of 10050 mAh. The pack is supplied with an attached cable for direct connection to devices that accept a single‑cell pack form factor while requiring extended run time. Its compact rectangular shape and cable lead make it suitable for portable electronics, DIY power modules and small backup applications where a higher capacity single‑cell solution is needed.

Advantages

The pack offers a high capacity in a single‑cell voltage configuration, providing extended run times compared with individual 18650 cells. The attached cable simplifies installation into devices or projects without the need for additional holders or wiring. Being rechargeable, the pack reduces the need for disposable batteries and supports repeated cycling for long‑term use. The 1S3P arrangement balances simplicity of voltage with increased capacity for applications that require low‑voltage, high‑energy storage.

Suitable for

• Portable electronics that accept a ~3.6 V rechargeable pack
• Battery backup for low‑voltage devices and small controllers
• DIY projects, custom housings and prototyping requiring a compact high‑capacity source
• Battery replacement in devices designed for single‑cell Li‑Ion packs

When it may not be suitable

This battery pack provides a nominal single‑cell voltage and is not suitable for devices that require higher voltages unless an appropriate boost converter or multiple packs in series are used. It is not intended for direct replacement in devices that require specific proprietary battery shapes, built‑in protection circuitry incompatible with the pack, or communication protocols. High‑current applications that exceed the continuous discharge rating of the assembled cells should be avoided.

Key specifications

• Cell configuration: 1S3P (three cells in parallel, single cell voltage)
• Nominal voltage: 3.6 V
• Rated capacity: 10050 mAh (aggregate)
• Chemistry: Lithium‑ion (Li‑Ion)
• Form factor: pack built from 18650 cells with attached cable

How to use

Connect the attached cable to the device input that accepts a single‑cell Li‑Ion voltage. Ensure the device polarity matches the pack cable wiring before connection. Charge the battery pack using a compatible Li‑Ion charger designed for a single‑cell pack and observe recommended charge current limits for 18650 cells. Use the pack within the manufacturer’s specified temperature and discharge limits and avoid deep discharge below the safe cutoff voltage specified for Li‑Ion cells.

What to consider before purchase

• Verify device compatibility with a nominal 3.6 V Li‑Ion pack and correct connector/polarity.
• Confirm required continuous discharge current does not exceed the pack’s safe rating for the assembled cells.
• Assess physical dimensions and mounting options to ensure the pack fits your device or project enclosure.
• Plan for charging: obtain a charger suitable for single‑cell Li‑Ion packs with appropriate current and safety features.

Usage recommendations

Use a dedicated single‑cell Li‑Ion charger and avoid exposing the pack to temperatures outside the recommended operating range. For installations requiring longer runtimes or higher currents, consider parallel or series configurations only when following safe battery management practices and proper balancing/charging equipment.
