2S Lithium Battery Balance USB Charging Cable for Car Model UAV with DC5V 2-3A Input DC7.4V 2000mA Output 15W Overvoltage Protection and Red Charging Indicator
2S Lithium Battery Balance USB Charging Cable for Car Model UAV 7.4V 15W
This 2S lithium battery balance USB charging cable is made for charging 7.4V lithium polymer packs used in car models and UAVs. It takes power from a DC5V 2-3A USB source and delivers a DC7.4V 2000mA output with a rated power of 15W. Overvoltage protection is built in, and the red indicator flashes during charging then turns off when the battery is full. The cable carries CE certification and a one-year warranty. It belongs to the 7.4V USB charging cable product series and uses a national standard plug. The core use case is straightforward: charging compatible 2S lithium packs without needing a separate balance charger.
Features and Construction
The cable is defined by its electrical ratings and protection rather than by physical materials, which are not stated. Its main construction facts are a DC5V 2-3A input, DC7.4V 2000mA output, 15W rated power, overvoltage protection, and a red charging indicator. These details matter for matching the cable to a suitable USB power source and a 2S lithium battery polymer pack.
Electrical Specifications
The input is DC5V 2-3A, which means the cable expects a USB power source capable of supplying between 2A and 3A at 5V. The output is DC7.4V 2000mA, matching the nominal voltage of a 2S lithium polymer battery. Rated power is 15W. These figures are the primary compatibility checks: the power source must meet the input range, and the battery must be a 7.4V 2S lithium polymer type.
Protection and Indicators
Overvoltage protection is included to help prevent excessive voltage from reaching the battery during charging. The indicator status is simple: the red light flashes while charging is in progress, and the full light is off when the battery is charged. This gives a visual cue without needing a separate meter. A one-year warranty and CE certification are also stated, providing defined product assurance.
Uses and Placement
This cable is intended for lithium battery charging in car models and UAVs. Its USB input makes it suited to charging from a USB port or USB power adapter that can supply the required DC5V 2-3A. The balance function and 7.4V output target 2S lithium polymer packs, which are common in these hobby applications.
Event or Professional Use
For car model and UAV users, the cable offers a way to charge 2S lithium packs from a USB source rather than a dedicated balance charger. The 7.4V 2000mA output and 15W rating define the charging capability. Overvoltage protection and the red indicator help make the charging state clear. It is not a universal charger; it is specific to lithium battery polymer packs within the stated electrical range.
Everyday Home Use
At home, the cable can be used with a suitable USB power adapter or USB port that meets the DC5V 2-3A input requirement. The compact role is to connect a 2S lithium polymer battery to that source. The national standard plug and CE certification are stated details. Users should ensure the battery is a compatible 2S lithium type and that the power source can deliver the required input.
Benefits and Buying Value
The value of this cable comes from its defined electrical ratings, overvoltage protection, and indicator system. It combines a USB input with a 7.4V 2000mA output for 2S lithium polymer charging, and it includes a one-year warranty. Buyers who already have a suitable USB power source can use it as a dedicated charging lead for car model or UAV batteries.
Reuse and Low Maintenance
No specific maintenance instructions are provided. As a charging cable, its practical upkeep is limited to checking the cable and connectors for damage before use and storing it dry. The overvoltage protection and indicator are built-in features that support routine charging checks. The one-year warranty covers the stated period.
Why Choose This Product
Choose this cable when you need to charge a 2S lithium battery polymer pack from a DC5V 2-3A USB source and want a DC7.4V 2000mA output with 15W rated power. It includes overvoltage protection, a red flashing charging indicator that turns off when full, CE certification, and a one-year warranty. It is aimed at car model and UAV lithium battery charging within those stated parameters.
