Dual Slot Intelligent Li Ion Battery Charger with Independent Charging Control
Dual Slot Intelligent Li Ion Battery Charger
This intelligent dual slot lithium ion battery charger is designed for charging one or two cylindrical rechargeable Li ion batteries simultaneously. With independent charging control, each slot operates separately to provide a convenient charging experience.
The charger features a DC 5V 2A Micro USB input and a DC 4.2V ±0.05V charging output. Each charging slot provides a charging current of 1.0A ±60mA. Its constant current and constant voltage charging technology supports controlled battery charging.
Two color LED indicators provide clear charging status information. The white light indicates charging, while the green light indicates that the battery is fully charged. The charger also includes reverse polarity protection and short circuit protection.
With a compact size of 121.5 × 66 × 31mm and a net weight of 90g, this charger is suitable for various battery charging applications requiring a compact dual slot solution.
