## Long description

ANSMANN Li‑Ion Akkupack 2S1P 2×18650 7.4V 3500mAh with Cable and Protection Circuit is a rechargeable lithium‑ion battery pack configured as two cells in series to provide a nominal 7.4 V output and a rated capacity of 3500 mAh. The pack is delivered with a pre‑fitted connection cable and an integrated protection circuit that guards against overcharge, overdischarge and short circuits, making it suitable for a wide range of portable electronic devices and DIY applications requiring a compact, rechargeable 7.4 V power source.
Advantages
The battery pack combines high energy density of 18650 lithium‑ion cells with a compact 2S1P layout to deliver consistent voltage and usable capacity. The integrated protection circuit adds safety by monitoring cell voltages and interrupting current in unsafe conditions. A fitted cable simplifies installation in projects and devices without needing additional wiring or holders. The rechargeable design reduces the need for disposable batteries, while the nominal 7.4 V output matches many small electronics and DIY systems.
Suitable for
Portable electronics and hobby devices that require a 7.4 V rechargeable source
DIY projects, robotics and model making
Cordless small tools and inspection lights with matching voltage
Backup power for sensors, small controllers and communication modules
When it may not be suitable
This pack is not intended for high‑current heavy duty power tools or applications that demand continuous currents beyond typical 18650 cell limits; suitability depends on the discharge rating of the internal cells. It may also be unsuitable where a different nominal voltage, higher capacity, or a physically different form factor is required. For installations exposed to extreme temperature, moisture, or mechanical stress additional protection or an alternative battery type may be needed.

Avoid charging with unsuitable chargers, and do not bypass the protection circuit. Observe standard safety precautions for lithium‑ion batteries: charge in a well‑ventilated area, keep away from heat sources, and do not puncture or crush the pack.
What to consider before purchase
Ensure the nominal voltage (7.4 V) and capacity (3500 mAh) match your device requirements
Verify the discharge current capability of the pack is adequate for your load
Confirm the physical size and cable connector suit your installation space
Assess environmental conditions (temperature, humidity, vibration) where the pack will be used
Usage recommendations
For safe, long service life charge and store the pack using chargers and procedures appropriate for lithium‑ion cells, avoid deep discharges, and replace the pack if you notice swelling, visible damage, or performance degradation.
