Li-Po battery, 153×65×10.2 mm, 8000 mAh, 3.7V, discharge current: 60C

Li-Po battery 8000 mAh 3.7 V - a powerful lithium-polymer battery cell of 1S1P format, designed for applications where high capacity, low internal resistance and the ability to deliver significant current are required.

The battery has a nominal capacity of 8000 mAh and a nominal voltage of 3.7 V, which corresponds to an energy capacity of approximately 29.6 Wh. The maximum charging current is 8 A (1C), while the standard charging mode is 4 A (0.5C).

One of the main features of the cell is a very high current output. According to the specification, the continuous discharge current is 480 A for up to 20 seconds, and the peak current is 1200 A for up to 2 seconds. This makes the cell focused on systems where high pulse currents are required.

The internal resistance of the battery is no more than 3 mΩ,

which helps reduce losses when working with high currents and ensures efficient energy transfer.

The case is made in a soft aluminum packaging (pouch) format, and the mass of one cell is approximately 198 g. Maximum dimensions are 153 × 65 × 10.2 mm.

The battery is designed for long-term operation: after 300 cycles under testing conditions, the specification provides for a residual capacity of at least 6080 mAh, i.e. at least 80% of the initial capacity.
