4S 200A w/Balance 2.7V 3.2V 3.7V 4.2V18650 Lithium Battery Cell PCB BMS Protection Board
Product Summary
1. Professional high current wiring design & workmanship, thus can withstand the shock of high current
2. Using fully enclosed heat-dissipating glue and a double-sided heat dissipation design, heat is dissipated in time, and the heat dissipation effect is better than others.
3. Dustproof, shockproof, anti-squeezing, and other protective functions
4. Complete overcharge, over-discharge, over current, short circuit, and equalization functions
BMS can monitor the voltage of the battery in real time and transmit the data to external devices through the communication interface for further analysis and processing.
Voltage sensor: A voltage sensor is a sensor device specifically designed to measure voltage, usually with high accuracy and fast response. A voltage sensor can be installed on the positive and negative terminals of the battery,
and the real-time voltage information of the battery can be obtained through the voltage value output by the sensor.
Generally speaking, the voltage acquisition frequency of common battery BMS is between tens of Hz and hundreds of Hz, and the accuracy is usually between a few mV and tens of mV.
This range can meet the needs of most application scenarios, but the specific collection frequency and accuracy need to be determined based on specific project requirements.

Wiring precautions:
1. Installing the protective board requires a certain amount of technical electronic knowledge.
2. When wiring, first connect the B- wire at the soldering pad position to the total negative terminal of the battery (the B- wire should be soldered to a short and thick wire) and solder the wired terminal to the battery pack first, and then insert the protective plate.
3. The connection between the battery terminal B- and the protection board terminal B- should be short and thick, otherwise it will cause the protection board to charge and discharge in advance and malfunction.
4. You need to use thick wires when wiring P+/P-. Wires that are too thin and too long will burn the board!
