## Summary description

ANSMANN Li‑Ion battery pack, configuration 2S2P, nominal voltage 7.2 V and capacity 5100 mAh using four 18650 cells. Includes connection cable and integrated BMS for cell balancing, overcharge and discharge protection. Suitable for portable electronics, DIY projects, backup power and devices requiring compact rechargeable packs.

## Long description

The ANSMANN Rechargeable Li‑Ion Battery Pack is built from four 18650 cells arranged in a 2S2P configuration to deliver a nominal voltage of 7.2 V and a usable capacity of 5100 mAh. The pack includes an attached connection cable and an integrated battery management system (BMS) that provides cell balancing and protection against overcharge and overdischarge. The compact rectangular pack is designed for portable electronics, DIY projects and small backup-power applications where a reliable, rechargeable 7.2 V supply is required.
Advantages
This ANSMANN battery pack combines the energy density of 18650 lithium‑ion cells with a 2S2P layout to increase usable capacity while keeping voltage suitable for many handheld devices. The integrated BMS helps maintain cell balance and adds safety by limiting overcharge and deep discharge conditions. The pre-attached cable simplifies installation in devices and custom projects, reducing the need for additional wiring or connectors.
Suitable for
Portable electronic devices that require a 7.2 V rechargeable source
DIY electronics projects, maker and prototype applications
Small backup power for routers, sensors or low-power equipment
Battery replacement in compatible chargers, instruments and toys
When it may not be suitable
This pack is not intended for applications that require higher voltages than 7.2 V or single-cell replacement; it is a multi-cell assembly with fixed voltage and form factor. It may not be appropriate for devices that demand very high continuous discharge currents well beyond the capability of typical 18650 cells or for environments where a sealed, IP-rated battery enclosure is required.
Key specifications
Cell type: 18650 lithium‑ion cells
Configuration: 2S2P (two series × two parallel)
Nominal voltage: 7.2 V
Rated capacity: 5100 mAh (total pack capacity)
Includes: connection cable and integrated BMS for balancing and protection
How to use
Connect the pack to the device using the attached cable, observing correct polarity. Charge the pack with a compatible Li‑Ion charger or a charging circuit designed for 2‑cell series packs and BMS-equipped batteries; follow the charger manufacturer’s instructions for charge current and termination. For installation in DIY projects, secure the pack mechanically to prevent movement and avoid short circuits by insulating exposed contacts. Regularly monitor the pack during initial use to confirm temperature and voltage behavior under the intended load.
What to consider before purchase
Verify that your device accepts a 7.2 V supply and that the connector/cable fits or can be adapted
Check the required continuous discharge current of your application against typical 18650 cell ratings
Ensure you have a charger compatible with Li‑Ion chemistry and a 2‑cell series configuration
Confirm space and mounting options for the pack in your device or enclosure
Usage recommendations
Store and operate the battery within manufacturer-recommended temperature ranges, avoid deep discharges for prolonged storage, and use a compatible charger. Replace the pack if you observe swelling, excessive heat during charge/discharge, or significant capacity loss.
