Main Features:
Voltage and Capacity Advantages:
This battery pack utilizes four 18650 lithium-ion batteries connected in series (4S1P structure), with a nominal voltage of 14.8V and a nominal capacity of 2600mAh. Compared to a single 18650 battery (nominal 3.7V/2200mAh), the combined voltage is increased fourfold and the capacity is increased approximately 0.7fold, meeting the voltage and energy requirements of high-power devices.
Safety and Protection Features:
It provides overcharge protection (4.28±0.025V per string), over-discharge protection (2.4±0.08V), and overcurrent protection (15-26A). The operating temperature range is 0-45°C for charging and -20-60°C for discharging, ensuring safe operation in extreme environments.
Dimensions and Weight Control:
The product could be assembled under you required max dimension, with an internal resistance of ≤280mΩ. Its weight-optimized design makes it suitable for applications such as small appliances, drones, and power tools. Compared to stacked batteries of the same capacity, the 18650 cylindrical structure facilitates high-consistency management and reduces system complexity.
Cycle Life and Stability:
The standard continuous discharge current is 0.2C, and the maximum continuous discharge current reaches 1C, supporting frequent use. The theoretical cycle life exceeds 500 cycles (tested according to Tesla standards), ensuring low maintenance costs and high long-term reliability.
Applications:
Home Devices:
Robot Vacuums: Available in a variety of models, providing continuous power to support cleaning tasks.
Cordless Vacuums: High energy density meets long-term operation requirements.
Power Banks and Charging Wrenches: Portable devices suitable for outdoor work or home emergencies.
Smart Home device:
Smart Trash Cans/Door Locks: Low-power devices that rely on a stable power supply for long-term operation.
Home Inverters: Ensure basic household power needs during power outages.
Industrial and Outdoor:
Power Tools: Lightweight equipment such as drills and nail guns, emphasizing a balance between portability and battery life.
Drones/RC Cars: High-discharge platforms support the operation of aircraft and power equipment.
Special Scenarios
Solar Power Systems: Store energy for use at night or on rainy days.
Medical Equipment: Portable instruments such as blood pressure monitors and blood glucose meters require a stable power supply.
