Lithium Li-ion 18650 3.7V 4.2V Battery Charger Board DC-DC Step Up Boost Module USB Type-C 2A Lithium Battery Fast Charge Module
Specification: ：Working temperature - 40~80 ℃ ：Input voltage range 4.2V~6.5V ：Output voltage 4.2V-28V adjustable ：Maximum power 5W ：0V activation, 2.9V trickle charging ：Up to 1A programmable linear charging current ：For single 3.7V lithium battery, fully charged with 4.2V ：Constant current/constant voltage charging, with over-temperature protection ：Soft start limit surge current, with battery reverse connection protection ：Low power standby, extended battery life ：Dual output of charging status, no battery and fault status display Description of charging indicator: ：The module can roughly judge the working status through two LEDs, CHRG is red, STDBY is blue. ：The red light of battery charging status is bright, the blue light is not bright, the blue light is full, and the red light is slightly bright. ：If there is a boost output, it will be different according to the output power. It is possible that the red light will always be on during charging. When the load is not connected, the blue light will be on, and the red light will be on slightly. instructions: ：The module supports type-c interface input and solder joint input marked on the back. You can choose one of them. The recommended voltage is about 5V. The module is marked with two outputs. The two outputs are the same. The lines are parallel. You can select one of them by yourself. How to connect the battery: ：If your battery is equipped with a protective plate, you can choose products without discharge protection. After connecting B+and B -, the battery must be short-circuited to T point before charging and discharging. ：If your battery is not equipped with a protective plate, choose the product with discharge protection. This is very important because over discharge of the battery is likely to cause the battery to be scrapped. Most competitive products of the same kind are not equipped with discharge protection. After the battery is connected with B+and B -, the T point cannot be short-circuited, otherwise the discharge protection will fail. ：After connecting the wire, you can use a screwdriver to adjust the output voltage you want. ：The battery is 3.7V lithium battery with a full charge voltage of 4.2V. The battery type can be 18650, polymer and other batteries. Instructions for use: ：*The product is linear charging, and the heating is normal, so it can be used safely ：*The batteries can only be connected in parallel, not in series. ：*The charging current should be 0.37C of the battery capacity, which is 0.37 times of the capacity. For example, the charging current of a 1000mAH battery is 400. ：*The charging connecting wire should not be too thin or too long. This connection has a high resistance. If it is too thin, the battery voltage will drop after flushing. ：*It is better to have good contact with the battery. Otherwise, the battery voltage will drop after flushing. ：*It is normal to generate heat when the current is high during boost operation. The higher the current is, the hotter it is. This is a normal phenomenon. The chip is equipped with overheating protection, which can be used safely. Package Contents: ：Booster module X1 ：Only the above package content, other products are not included. ：Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm. |
