Specifications:
  • Circuit board B- connects power negatively, B+ connects positive. Don't inversely connect, it will result in the burning of the board. Make sure there is insulation between power and circuit when installing the battery

  • 1A output is not continuous current, it changes according to USB connecting load, automatic current output as per load

  • If a battery is connected incorrectly, the reverse polarity will burn the circuit. So, make sure to check the battery polarity when connecting.

  • Input Voltage: 3.7V~5.5V | Output voltage: 5V | BAT Discharging Stop Voltage: 2.9V

  • Charging Current: 1A(max); Output Current: 1A(max); Discharging Efficiency: 85%(input 3.7V output 5V/1A)

  • Charging and discharging indication; Internally installed charging and discharging power MOS; Preset 4.2V charging voltage, precision ±1%; Max 8uA standby current;

  • Support trickle mode and zero voltage charging

  • Intelligent temperature control and overtemperature protection; Integrated Output overvoltage protection, short circuit protection, overload protection, overcharging and over-discharging protection

Note:

Charge indication of this power bank PCB board: When charging: red light flashing; Full charged: red light for a long time.

FAQ:

why the display percentage is not accurate, the battery power is only 50%, but it shows 80% after assembly?
Whether you are using a new battery or an old one all need to be discharged before use(charge your mobile phone), then turn it off charge it once again. If it still cannot be solved, it is caused by large internal resistance and inconsistent capacity.

Special Instruction:

When connecting the board for the first time, connect the battery and then connect the micro USB charger and charge the battery to full capacity before using it.
It is required to prime the IC so that it starts and shuts down accurately

Product description:Features: Step up the board: use 18650 battery to step up to 9V. Charging board???input 5V 1A or 2A to charge the 18650 battery. Battery protection board: over-charge protection, over-discharge protection, over-current protection, over-temperature protection, output short circuit protection. UPS???Uninterrupted power supply??????if input 5V, it will charge the battery and no use the battery power; if power failure, it will automatically use the battery power. Lithium Battery Step Up Module only, other accessories demo in the picture are not included!The four-in-one booster board uses small tips:
1. When using as a UPS, the SW pin should be shorted, the output should be kept in real-time, and the power can be turned off to start the battery at any time.
2. As a mobile power supply, it can be connected to the SW switch, it is turned off when not in use, there is no static loss, and it is very energy-saving.
3. If the SW does not want to connect the switch, it can also be shorted, and the output indicator will be soldered after all the tests are completed. This can reduce the current consumption of ten or twenty mA without affecting the normal output of the circuit and compare the power saving.
4. During the operation, it is possible that the board will enter the protection state and not output due to various reasons (mistakes, misconnections, etc.). After the problem is removed, the board charging port can be connected to the 5V charging, and the board is re-powered. The re-output can be activated.

  • Output: 5V 1A or 5V 2.1A | Output Interface: Dual USB output: 5V/2.1A

  • 4 onboard SMD LED to display battery charge level; Separate 5mm LED to use the power bank as a torch

  • Designed for 18650 battery DIY power bank: The battery of the 18650 battery must be flat, and the length is 65MM. The pointed battery cannot be used. If you are using old batteries, different capacities, different brands are not available, the assembled battery is guaranteed to be at least 3.5V per voltage. If the voltage is too low, it will not be charged. (It also support lithium battery, mobile phone battery, and tablet battery)

  • Overcharge protection | Over-discharge protection | Overcurrent protection | Supported connection methods: It is possible to connect only one lithium battery or multiple lithium batteries in parallel. The capacity of the connected battery is no more than 200,000 mAh, As long as the battery with a voltage of 3.0-4.2V can be used.

Note:

Charge indication of this power bank PCB board: The word "IN" will be shown in the display; Output indication: Long press the LED button after turning on the load, Start output, The word "OUT" and the current and voltage of 5V 1.0A or 5V 2.1A will be displayed in the display.
The positive pole of the battery is connected to B+ and the negative pole is connected to B-, do not reverse it. If it is reversed, it will burn out!!!!

FAQ:

why the display percentage is not accurate, the battery power is only 50%, but it shows 80% after assembly?
Whether you are using a new battery or an old one all need to be discharged before use(charge your mobile phone), then turn it off charge it once again. If it still cannot be solved, it is caused by large internal resistance and inconsistent capacity.

Special Instruction:

When connecting the board for the first time, connect the battery and then connect the micro USB charger and charge the battery to full capacity before using it.
It is required to prime the IC so that it starts and shuts down accurately

    Product description:Instructions:
    • The first test should be a fully charged battery.

    • Connect the battery and load, use a micro USB power supply (do not use desktop or laptop USB power)

    • Direct start test needs only one press of the "OK" button, the tester can automatically develop an appropriate termination voltage of the battery full charge voltage, and will start flashing after the test three times. Need to develop artificial termination voltage only when the battery voltage display state by pressing "+" or "-" buttons to modify the termination voltage display beginning with P, behind the representative voltage resolution 0.1V, set up after pressing the "OK "start testing.

    • After the start of the test, the tester will control the load of the electronic switch is turned on, the test data shows that the process will release capacity (Ah), current discharge current (A) and battery voltage (V) between the wheel was. When the battery voltage reaches the set cut-off voltage, load control switches off the tester display data stays in capacity (Ah) and above and the corresponding indicator flashes quickly together, now displays the actual capacity of the battery is discharging capacity, press "OK" to terminate flashing allows stable data display, press again "OK" button to return to the power-on state can just replace the battery test the next section

    Error codes and their meanings:
    • Err1: battery voltage is above 15V

    • Err2: battery voltage is lower than the termination voltage

    • Err3: Battery can not afford to load or discharge current line too much resistance

    • Err4: over-current (current exceeds 3.1A)

    • Note: Use the resistance for the discharge process, the resistive load will heat, please handle safety!

    • When the terminal displays nothing then a small voltage does not affect the actual measurement, if you are shorting the input terminal

    Specification:
    • Power supply voltage: DC 4.5 - 6V (micro USB connector); Operating Current: less than 70mA

    • Discharge voltage: 1.00V-15.00V 0.01V resolution Termination voltage range: 0.5-11.0V Supported by current: 3.000A 0.001A resolution

    • Maximum voltage measurement error: 1% + 0.02V Maximum current measurement error: 1.5% + - 0.008A

    • Maximum battery capacity range: 9999Ah (1Ah = 1000mAh) greater value by shifting the decimal point to switch, when the display is less than 10Ah X.XXX, as shown above to achieve 10Ah XX.XX, and so on.

    • Check the image for Instructions Manual; Maximum capacity statistics support 9999Ah (9999000mAh); Package Included: 1Pc x battery capacity tester 1Pc x Load resistor
