Product Description:

A battery management system (BMS) is an electronic system that manages a rechargeable battery (cell or battery pack), such as by monitoring its state, calculating secondary data, reporting that data, protecting the battery, controlling its environment, and balancing it.

  • The successful start of the drill requires three 15C-20C power battery, or six 10C-15C power battery (ordinary 18650 can not start the drill!!). 

  • strictly according to map wiring 0V, 4.2V, 8.4V, 12.6V, do not deliberately short circuit. 

  • When the load of the brush motor is used, try to connect a non-polar capacitor (withstand voltage above 25V, capacity 10uF-100uF) to the motor's positive and negative terminals to prevent the reverse spike from the motor. Break the MOS tube. 

  • 3 groups of batteries in series, please ensure that the voltage of each group of batteries, if not the same, please fill each battery separately and then use it in series. In the Discharge test, the battery that has a faster voltage drop is poor battery. 

  • A balanced charge is only auxiliary functions, try not to put a good battery and poor battery mixed together! 3 sets of battery capacity/resistance closer to the better! (2 good battery +1 Poor battery use effect = 3 poor battery use effect).

A battery management system (BMS) is any electronic system that manages a rechargeable battery (cell or battery pack), such as by monitoring its state, calculating secondary data, reporting that data, protecting the battery, controlling its environment, and / or balancing it.
Specification:
Resistance Inner ≤15 mΩ; Self-Consumption Working Current:≤60 uA; Sleep Current (when Over-discharge): ≤10 uA; Working Temperature Range: -30/+80 ???
Attention When Connecting:
When we connect BMS with cells or disassemble BMS from battery pack, the following order and regulations must be complied with to avoid damage of components of BMS and problems of not protecting of cells.
In order to achieve the best performance of BMS and to run the longest distance, all the battery must be matched well (Each battery voltage ???0.05V, IR???15 mΩ, capacity???30mAh) to make sure the better consistency of the battery.
Cell must be connected in parallel first, after then connected in series.
Connection: 1. Connect charging /discharging wire, battery pack negative wire.
2. After confirm the wires are connected OK, plug the connector cable in the BMS
Do not plug connector cable in the BMS before connect wire.

Notes:
  • Please select the appropriate protection board according to the actual battery type and series connection.

  • Before the protection board is installed, the battery must be matched well, and the old and new batteries cannot be mixed.

  • Please remove the cable before wiring, and connect all the wires, and then confirm that the wiring is correct before plugging in the cable. When wiring, the control wiring diagram is gradually connected from the negative pole of the battery. For the thick line, please select the appropriate square wire according to the actual load current value.

  • When the working current is too large, please add tin to the tinned part of the front and back of the protection board, or thicken the copper wire to increase the overcurrent capability of the circuit board.

  • If you need a temperature protection function, add 10K NTC resistor (refer to the image). The factory default is no temperature protection resistor.

This is another great IIC/I2C/TWI/SPI Serial Interface. As the pin resources of FOR Arduino controller is limited, your project may be not able to use normal LCD shield after connected with a certain quantity of sensors or SD card. However, with this I2C interface module, you will be able to realize data display via only 2 wires. If you already has I2C devices in your project, this LCD module actually cost no more resources at all. It is fantastic for Arduino based project.
  • LCD display module with Green/Yellow blacklight. Wide viewing angle and high contrast. I2C Interface not included only LCD Module
  • Built-in industry standard HD44780 equivalent LCD controller

  • Before the protection board is installed, the battery must be matched well, and the old and new batteries cannot be mixed.

  • Please remove the cable before wiring, and connect all the wires, and then confirm that the wiring is correct before plugging in the cable. When wiring, the control wiring diagram is gradually connected from the negative pole of the battery. For the thick line, please select the appropriate square wire according to the actual load current value.

  • When the working current is too large, please add tin to the tinned part of the front and back of the protection board, or thicken the copper wire to increase the overcurrent capability of the circuit board.

  • If you need a temperature protection function, add 10K NTC resistor (refer to the image). The factory default is no temperature protection resistor.
