LaskaKit Li-Ion Battery 2x18650 2S1P 7.4V 3200mAh

Product detailed description

The original LaskaKit 2S1P battery pack is assembled from two 18650 cells (2S1P configuration) with a nominal voltage of 7.4V and a capacity of 3200mAh. The battery is equipped with a protective and balancing circuit that protects individual cells against overcharging, over-discharging, and short circuits. The battery pack is suitable for projects requiring higher voltage with compact dimensions and stable performance.

The battery is delivered partially charged (approx. 60-80%) for optimal storage. We recommend a full charge before first use. If you do not measure voltage at the output after delivery, connect the battery to a charger – this will activate the protection circuit.

The battery includes a protection circuit that keeps the battery voltage from getting too high (overcharging) or too low (over-discharging), which means that the battery will be disconnected once it is discharged to 3.0V. This circuit also protects the battery from short circuit. However, even with this protection, it is very important that you only use a LiIon / LiPoly CV/CC charger. We recommend using our PD-IP2326 Li-ion cell charger. and set the required current with a jumper or trimmer.

Important Notice and Safety:

• The user bears full responsibility for the correct connection, charging, and use of the battery.
• Charge exclusively with a charger designed for 4S Li-Ion batteries (8.4V CC/CV).
• Do not use NiMH/NiCd chargers or other incompatible sources.
• Never short-circuit the battery terminals or damage it mechanically (drop, dent, puncture).
• Do not charge or use unattended.
• Do not expose to high temperatures, direct sunlight, fire, or moisture.
• Use only in devices with appropriate current, voltage, and thermal protection.
• In case of swelling, odor, overheating, or other abnormalities, stop using the battery immediately.
• Always insulate the contacts against short circuits before disposal.
