Frequently Asked Questions (FAQ):
Q1: What is the advantage of the 8C / 20A discharge rate?
A1: The 8C / 20A discharge rate means this battery can deliver 20 amps of continuous current. This is significantly higher than standard 1C (2.5A) batteries, making it capable of powering high-torque drills, saws, and other high-demand equipment that standard cells cannot handle.
Q2: What does "≤14mΩ" internal resistance mean for my devices?
A2: Ultra-low internal resistance (≤14mΩ) means the battery generates much less heat and loses less energy during high-current discharge. This translates to more power reaching your device and longer battery life, especially under heavy loads.
Q3: What voltage and shape configurations are available?
A3: We offer a wide variety of configurations. Simply select your desired voltage (7.4V, 11.1V, 14.8V, 18.5V, 22.2V) and preferred nickel tab layout (Parallel, Triangle, Square, Convex) from the dropdown menu above to find the perfect fit for your device.
Q4: Are the nickel tabs already welded to the batteries?
A4: Yes! The nickel tabs are pre-spot-welded for easy connection. There is no need for complicated soldering or spot welding equipment. You can connect them directly to your device's wiring.
Q5: What is the temperature range for this battery pack?
A5: This pack supports a wide discharge temperature range of -20°C to 80°C. This makes it suitable for use in cold outdoor environments as well as high-temperature operation conditions.
