Rechargeable Battery Pack ANSMANN 2S2P 4×18650 Li‑Ion 7.2V 5200mAh

Rechargeable Battery Pack ANSMANN 2S2P 4×18650 Li‑Ion 7.2V 5200mAh is a compact, rechargeable energy source assembled from four 18650 lithium‑ion cells in a 2S2P configuration. The pack provides a nominal voltage of 7.2 V and a usable capacity of 5200 mAh, offering a balance of runtime and size for portable devices that accept 7.2 V battery packs. Its design focuses on replacing disposable batteries or older sealed packs with a modern rechargeable solution suitable for hobby electronics, DIY repairs and equipment that use this form factor.

Advantages

The ANSMANN 2S2P pack delivers stable voltage output and consistent capacity across charge cycles, helping to extend operating time compared with single‑use batteries. The use of 18650 Li‑Ion cells yields a high energy density in a relatively small package, while the 2S2P configuration provides both the required voltage and increased capacity. The rechargeable nature reduces waste and operating cost over time. The pack is compatible with common chargers and devices designed for 7.2 V packs when proper connectors and charging methods are used.

Suitable for

• Portable electronic devices that accept 7.2 V battery packs
• Hobby electronics and RC models with matching form factor
• DIY replacements for worn or depleted battery packs
• Portable tools, lamps, and measuring instruments designed for lithium‑ion packs

How to use

Install the pack into compatible equipment following the device manufacturer’s instructions for battery orientation and connector type. Charge the battery pack only with a charger suitable for lithium‑ion packs and for a nominal voltage of 7.2 V; observe recommended charging current limits for 18650 cells. Avoid charging with unapproved or incompatible chargers. During installation and charging, ensure contacts are clean and dry and that the pack is secured to prevent short circuits or mechanical damage.

Usage recommendations

Store the battery pack in a cool, dry place when not in use and avoid prolonged exposure to high temperatures. Do not disassemble, puncture, or crush the pack. For longest life, follow recommended charging cycles, avoid deep discharge below the device’s safe cutoff, and use a compatible protection circuit if the application does not include one.
