Board size: 50mmX37mm Finished Size: 50mmX37mmX17mm (length X width X height maximum position size, contains copper foot height) Instructions: 1. The first test should be a fully charged battery. 2. Connect the battery to be tested positive to positive input, a negative input to the negative, can not be reversed (with load reversal may damage the circuit)! Load connected to the output of the positive and negative output, to work through the tester micro USB power supply (not available desktop or laptop USB powered), then the battery voltage. 3. Direct start test need 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. 4. 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, about the 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: overcurrent (current exceeds 3.1A) Err5:Improper use or incorrect wiring has caused the device to be burned out and cannot be used (current sampling or control switch MOS burned out). Note: Use the resistance of the discharge process, resistive load will seriously heat, please pay attention to safety! This circuit voltage in order to improve the measurement accuracy, specially designed DC bias, when the terminal displays nothing then a small voltage does not affect the actual measurement, if you are shorting the input terminals (absolute 0V) will show 0 No retail package Quantity:1Pc Due to the difference between different monitors, the picture may not reflect the actual color of the item.

TP4056 (Micro USB with Current Protection) 1A Li-ion Battery Charging Module
TP4056 1A Li-Ion Lithium Battery charging Module with Current Protection – Micro USB This TP6405 1A Li-Ion Battery Charging Board Micro USB with Current Protection is a tiny module, perfect for charging single cell 3.7V 1 Ah or higher lithium-ion (Li-Ion) cells such as 16550s that don't have their own protection circuit. Based on the TP4056 charger IC and DW01 battery protection IC this module will offer 1A charge current then cut off when finished. Furthermore, when the battery voltage drops below 2.4V the protection IC will switch the load off to protect the cell from running at too low of a voltage and also protects against over-voltage and reverse polarity connection (it will usually destroy itself instead of the battery) however please check you have it connected correctly the first time. USING THE MODULE: Connect micro USB cable for power, or 5V DC to pads marked IN+ and IN- on the left-hand side of the module Connect cell to charge to B+/B- pads on the right-hand side of the module. A load (something for the battery to power) can be connected to the OUT+/OUT- pads on the right-hand side Important! Disconnect load when charging The red LED indicates charging in progress, green LED indicates charging has finished. Never charge your battery at a rate greater than 1C. NOTE: 1. Ampere meter can only be connected to a 5v input end of the module. 2. It is better than the charging current is 37% of the battery capacity. If you charge the battery of 1000mAh, a current of 400mAh is enough. 3. The connection wire should not be too thick. 4. Make sure the connect point is good. 5. If the input voltage is too high, like 5.2v, the current will be less than 1000mA, it is normal. It is protection function, auto-subtract the charging current to avoid burn damage to the chip. 6. NO Reverse polarity. You can check our others BMS. Click here Features: Led indicator: red is charging Green is fully charged. Current Protection: Yes Inversed polarity: NO. Use mature charging chip TP4056 for simple peripheral circuits, good protection performance, and high charging accuracy. Fully machinery automated processing, all patch parts manufacturing.
