2x 18650 Battery Charge Board V8

2x 18650 Lithium Battery Charge and Power Bank Board V8

5V 3A Usb Output Power Supply Battery Shield V8 Battery Protection

You must insert the batteries into the sockets correctly. If inserted in reverse, the product is damaged. Inside the battery slots, the + - marks are printed on the pcb.

Batteries are not included with the product.

     This module is used to charge 2 pieces of 18650 batteries and to transfer energy from these batteries to the outside. It is a portable mobile power supply that supports two voltage outputs, 3V/1A and 5V/2.2A. The 5V voltage output rated current is 2.2A, it supports a maximum of 3A current (not recommended for overload.). The current output depends on the quality of the 18650 battery. Charging is done via Micro usb and Type C usb sockets.

     It has 4 level battery capacity indicator leds. It turns off after running for 3 sec.  Overcharge or over discharge battery protection is available. At the bottom section there are also a micro usb input and type-c sub output sockets. There is one on off button. 3.3V and 5V expansion ports are available; thus usage becomes easier according to customer needs and the problem of the low number of connections is significantly reduced. It gives an alarm when the battery voltage drops below 3V. When it drops below 2.4V it shuts down completely and performs no operation.

     The switch on the board allows users to switch between Hold (standby) and Normal (normal) modes. In Normal mode, when the current is very low, charging turns off automatically. In Hold mode, charging continues until the over discharge protection is activated.

Usage:

    After purchasing the product, first insert the battery to charge and activate it. Make sure that the positive and negative poles of the batteries are inserted correctly, otherwise the module may be directly damaged. Do not pull out the battery directly during use without turning off the module. Otherwise, the module activates the protection function and may cause the battery not to turn on when the battery is reinserted. In this case, before reinserting the battery, turn off the module and then turn off the battery (press and hold the button to turn off the battery).

    The module has an energy saving function; approximately three seconds after it is turned on the indicator light goes out, but the device is still in working condition. If you want to turn off the device, press and hold for two seconds so that the led light does not light up.

    The maximum output power of the module is 5V/3A, and it also depends on the device used and the battery power. If the current of the load device is more than 3A, it is recommended to start the module before connecting the load; because excessive current may lead to integrated circuit failure. It is assumed that the excessive load current is too high for protection.

    The battery voltage normally works between 3.2V and 4.2V; please do not connect the batteries in series. When connected in series the voltage increases. If the battery capacity needs to be increased in parallel, do not connect the batteries in series.

Attention:

•     The power output depends on the quality of the 18650 battery. LED indicator (green means full, red means charging). The battery pack must be inserted according to the positive and negative poles clearly marked on the board. Installation errors burn the module!
•     This product does not include an 18650 battery.
•     The battery voltage normally works between 3.2V and 4.2V; please do not connect the batteries in series. When connected in series the voltage increases. If the battery capacity is to be increased in parallel, do not connect the batteries in series.
