Care Guide
This is a specialized USB charging cable designed specifically for 7.4V Lithium-Ion (Li-ion) battery packs, commonly used in RC cars, drones, and hobbyist electronics. The charger features a standard USB-A input (5V 0.5-2A) and a dedicated SM-3P (3-pin) connector output providing 7.4V at 1000mA. The unit is housed in a translucent blue plastic casing, allowing for a glimpse of the internal circuitry, and comes in its original protective poly bag packaging. This is an essential replacement or spare part for hobby enthusiasts who need a reliable way to charge their battery packs via any standard USB port, such as those found on computers, power banks, or wall adapters. The lightweight and compact design makes it highly portable for field use.(FF)
Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.
Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.
Storage: Stuff with paper to maintain shape when not in use. Store in a dry, ventilated area to prevent mold. Rotate between multiple pairs to extend lifespan.
Usage Notes: Designed for basketball. Not recommended for hiking, long-distance running, or other specialized sports where different performance features are required.
