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.

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!

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.
5. Special usage (very special): If you want to supply 5V to the load when there is external 5V power supply, 3.7V (no boost) for the load directly from the lithium battery when there is no external power supply, you can connect the positive output line of the board directly from the S-pad lead of the SW pin load.Specification:

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

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 is required to prime the IC, so that it starts and shuts down accurately

Note:
Please allow 1-3mm error due to manual measurement.
Due to the difference between different monitors,the picture may not reflect the actual color of the item.

Product description:

TP5100 is a double switch buck 8.4V, single cell 4. 2V lithium battery charge management chip. Its ultra-compact QFN16 package and simple external circuit, making TP5100 ideal for portable equipment so large current charging management applications. Meanwhile, TP5100 built-in input overcurrent, Undervoltage protection, over-temperature protection, short circuit protection, battery temperature monitoring, reverse battery protection.

TP5100 has 5V-18V wide input voltage, dual battery trickle charge into pre-charge, constant current, constant voltage three-phase, pre-charge current trickle charge current through an external resistor adjustment, the maximum charge current up to 2A. TP5100 with a frequency of 400kHz switching mode makes it possible to use a smaller outer Suo device and the large current charging still maintains a smaller amount of heat.
