High capacity of 5000 mAh for long battery life

The 5,000 mAh capacity provides sufficient power for long-term device operation and reduces the need for frequent charging. The 21700 format also offers high energy density and is a suitable solution for more demanding professional applications.

Unprotected RAW design for professional systems

This is a unprotected RAW cell that does not contain its own protection electronics. It is designed for compatible devices and battery packs equipped with an external BMS system, which provides protection against overcharging, over-discharging, short circuits, and overloading.

15 A continuous current and up to 70 A peak current

The cell provides a stable continuous discharge current of up to 15 A, making it capable of powering even devices with higher power requirements. Under short-term loads, it can deliver a pulse current of up to 70 A for a maximum of 2 seconds, for example during startup or a brief power spike.

Lifespan of over 500 charge cycles

The high-quality Li-ion cell offers a service life exceeding 500 charge cycles. When properly charged, used, and stored, it provides reliable performance over a long period and helps reduce the need for frequent battery replacements.

Reliable operation in various climatic conditions

An operating range from –20 to +60 °C allows the cell to be used in both cold and warm environments. Its stable performance is particularly valuable for professional equipment, power systems, and other applications exposed to variable operating conditions.

Flat contact and precise dimensions

The Flat Top design with a flat positive contact is intended for compatible devices and battery packs. The cell has a diameter of 21.45 mm and a height of 70.65 mm, so it is necessary to verify the available space, contacts, and support for the 21700 format before use.
