Frequently Asked Questions (FAQ):
Q1: What voltage and shape configurations are available?
A1: 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.
Q2: Are the nickel tabs already welded to the batteries?
A2: 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.
Q3: What is the advantage of the multiple safety designs shown in the images?
A3: These battery packs feature a bottom sealing cap and safety heat-dissipation vents. Combined with a fully inspected secondary explosion-proof design, these features safely release internal gases in extreme conditions, effectively preventing battery swelling, leakage, or explosion.
Q4: How long does a 2000mAh battery take to fully charge?
A4: Using a standard 1C charger (2A charging current), a single 2000mAh cell typically takes approximately 1 to 1.5 hours to reach a full 4.2V charge.
Q5: What is the advantage of the 1500+ cycle life?
A5: A 1500+ cycle life means these batteries can be recharged and used over 1500 times. This makes them extremely economical, reducing the need to buy new batteries frequently and minimizing environmental waste.
