Description: Programmable linear charging current up to 1A. For a single 3.7V lithium battery, a full charge voltage of 4.2V. Constant current/constant voltage charging with overheating protection. Soft start to limit inrush current, with battery reverse protection. Low power consumption in standby mode to extend battery life. Dual-output charging status, with display for no-battery and fault status. Sliding current charging can be activated at 0V - 2.9V. Operating temperature range: -40 ~ 80℃. Input voltage range: 4.2V ~ 6.5V. Note: The battery should not be connected in reverse as it can easily damage the main board. The voltage at the battery terminals should not exceed the product's overshoot voltage. Batteries cannot be connected in series but only in parallel. Several batteries can be connected in parallel, though it's not advisable to have too many.
