123electric BMS123 Smart Gen3 - complete set (4 cells) with Bluetooth 4.0

123electric BMS123SM-G3-SET Complete solution for LFP, LTO, NMC and Li-Ion cells for battery manufacturing with monitoring and management via Bluetooth using a smartphone, iPad, tablet or other device. Compatible with LTO, works with cell voltages between 1.5-5.0 V High-precision dual-range SOC current sensors for measuring a wide range of currents up to 50% Error history to see when, in which cell and what error occurred SOC logging for the last week More accurate temperature measurement near the cell pole Firmware update over the air Easier configuration Included in the package are 1x Begin module (SOPGWL0310), 1x End module (SOPGWL0417), 2x Between module (SOPGWL0298), cell interconnect wire, 2x current sensor (500 A) for independent monitoring of input and output current. BMS123 Smart is a fully modular system. Each battery cell is equipped with one small printed circuit board. Three types of cell circuit boards are required for installation. One Begin board installed on the first cell, one End board installed on the last cell and a regular board on each cell between the first and last cell. For a battery pack consisting of 4 cells (12 V), you only need one Begin module, one End module and two regular cell modules. Begin module: End module: For larger batteries (24 V, 48 V, etc.), you can start with a complete set (4 cells) and simply purchase additional regular cell modules to be installed on additional cells between the first and last cell. This way, you can easily create a complete system for any number of cells! Example of battery configuration: 24 V pack (with 8 LiFePO4 cells): BMS123 Smart - the complete set contains 4 cells (1× First IN, 1× Last OUT, 2× Single CM) for the next 4 cells, you just need to purchase 4 additional Single Cell (CM) modules. 48 V pack (with 16 LiFePO4 cells): For an additional 12 cells, you simply purchase 12 more single-cell modules (CM). Example of a 2P4S (e.g. 12 V [2 x 100 Ah]) battery configuration: For this installation, you only need a 12 V BMS kit. Two parallel cells are still just one cell. Smart BMS123 app Easy installation directly at the cell level. BMS123 Smart is really Smart: this BMS system has no main control unit! Everything is integrated directly in the cell modules. The IN and OUR cell modules contain all the hardware components for the basic operation of the entire BMS system. In addition, the OUT cell module collects all relevant data and transmits it via Bluetooth 4.0 LE (low energy) to your tablet or phone with iOS or Android. Accessing information about your battery has never been easier. Monitor everything remotely, including the daily production of the photovoltaic cells, the daily energy consumption or, for example, the voltage of all cells on a single screen. Get a complete overview of your home energy storage on your Smartphone or tablet! Smart advantages of the BMS123 system: Small-sized board installed directly on the terminals of each cell Single-wire communication, easy battery installation Simple wiring of the entire system designed for energy storage markets No additional main control unit No external battery required for operation, the BMS system is powered directly from the battery Detailed monitoring and balancing for each cell separately Check the status of all cells on one screen Excellent price-performance ratio: robust and reliable system at a very competitive price Adjustable integrated low-power bi-stable relays allowing to disconnect the charger and load at predefined levels Optional free software for iOS or Android allowing to get a detailed Advanced Monitoring Dashboard Android App iOS App BMS123 Smart and Victron In addition to connecting one of Victron Energy’s lithium battery systems to the Multi or Quattro, it is also possible to connect a third-party system. In most installations, the Battery Management Systems (BMS) that come with some type of lithium battery system will need to have control over the charging and discharging of the batteries. Generally, they will want to stop the charging process when the maximum cell voltage rises above a certain threshold, and they will also want to turn off the load that is discharging the battery when the minimum cell voltage drops below its threshold.
