DC Smart Portable Storage Battery Charging Machine
Overview
The FLD-C series smart portable storage battery charger is a high-frequency, intelligent switch and rectifier type charger. It utilizes the standard three-stage charging method (constant current, voltage limiting → constant voltage, current limiting → float charge). By setting the appropriate charging parameters, the battery pack can be charged according to the standard procedure. With high precision in voltage and current stabilization, a low ripple factor, comprehensive protection functions, and stable performance, it is ideal for battery maintenance and long-term use.
Features
- Customizable charging parameters: equalizing charge voltage, float charge voltage, equalizing charge current, float charge current, total charging time, float charge duration, etc.
- High accuracy in voltage and current regulation, minimal ripple, and reliable operation.
- Standard three-stage charging process. Once the parameters are set, the entire charging process can be fully automated.
- Ultra-wide input voltage range with excellent adaptability.
- Current-limited output with precise control over battery charging.
- Utilizes soft-switching technology for high efficiency and good electromagnetic compatibility.
- LCD display in English for easy operation and user-friendly interface.
- Automatic shutdown function. The charger will stop automatically under these conditions: reaching the set total charging time, reaching the set float charge time, or internal fault detection. Users can also manually stop the charging at any time.

A lip gloss tube is a small, cylindrical container used to hold and dispense lip gloss. Lip Gloss Empty Tubes.It typically has a twist or click mechanism at the bottom that allows the user to push up the lip gloss from the tube and apply it to their lips.Empty Lip Gloss Containers. The tube is often made of plastic or metal and is compact and portable, making it easy to carry around in a purse or pocket. The top of the tube usually has a small applicator, such as a brush or sponge, that the user can use to apply the lip gloss smoothly and evenly. Lip gloss tubes come in various sizes, colors, and designs, catering to different preferences and styles.
