For enhanced security, the battery has two onboard fire-extinguishing modules. 3 Battery Overview 3.1 System Connections Below is an example system connection diagram with an EG4 charge controller and EG4 inverter: Note: During single-battery operation, the battery terminals can directly connect to the equipment.
It can be installed in a standard 19-inch cabinet and communicates with external devices via CAN/RS485 as well as with other EG4® batteries via RS485. The modules can be connected in parallel to meet expansion requirements. Inter-battery communications support a maximum of 64 modules for the 6 DIP switch model or 16 modules for the 4 DIP switch model.

3.2.2 Emergency Stop (RSD, ESS Disconnect) The optional ESS disconnect can be used to shut down all batteries and inverters (if equipped) with the push of a button. This integrated safety feature ties directly into the battery communication system via an open Battery-Com port using a standard Cat-5/6 ethernet cable.
8 – 9 months in prolonged storage. Environmental Factors The environment you store your EG4® battery in can greatly affect the health of the battery. For best results, the temperature should remain moderate, between 41°F and 68°F (5°C and 20°C).
4.2.2 Requirements for Installation Warning Do not put EG4® 48V-LL-S batteries in series. The BMS and internal • components are not designed to handle this setup, which could cause the modules to fail. • Avoid exposing batteries to conductive materials, such as water, strong oxidizers, and strong acids.
Tools needed for installation The tools required may vary depending on how you choose to mount your battery. Typically, the following items are needed to install the battery into an EG4® battery rack solution or general racking. 1. 10mm socket and ratchet 2.
Warning Do not ground rack/cabinet or door to negative or positive bus bars! In this image, there are 6 EG4®-LL-S 48V 100Ah batteries wired in parallel. This battery bank still maintains the appropriate 48V needed for a system. However, the Amp hour rating of this bank has increased to 600Ah.
4.3 Battery Communications Each EG4® battery is designed with you in mind, displaying as much information as possible in the simplest manner. EG4® Electronics includes the option of connecting the battery to PC software to monitor the module status. This allows you to see and understand exactly what the battery is doing as well as troubleshoot if problems arise.

4.4 Installing with Different EG4 ® Battery Models EG4® LL-S batteries can communicate with all EG4 ® 48V server rack modules. However, you will need to apply the proper firmware to any LL-V1 and/or Lifepower4 modules before installation. Please visit http://www.eg4electronics.com/downloads for the latest firmware.
5 Battery Operation 5.1 LCD Screen Each module has a built-in HD LCD touch screen used to display important information about the cells including voltage, current, temperature, SOC, and others. 5.1.1 Button description There are 4 function buttons below the display with detailed descriptions, as shown in the table below. No.

Open the folder to access BMS_TOOLS. Right click and click “Run as administrator.” You may see a popup for Microsoft Defender appear. Click “More info,” and then click “Run anyway.” 4. You will be brought to the main page of BMS Tools.
Image 5.3.2 Interfacing with BMS Tools 1. Press the ON/OFF button on the battery to power off the BMS. 2. Set the DIP switch ID address of the battery to Address 64 (4-pin DIP, see image A) or Address 16 (6-pin DIP, see image B).
7. Open BMS Tools. Under “Monitor Status,” verify “COM” matches the battery COM from the previous “Ports” list. Verify “Baud Rate” is set to 9600, and “PACK ID” is set to 16, then click “SearchDevice.” After about 30 seconds, BMS Tools will begin the monitoring process and pull real-time data from the BMS.

This protection also aids in keeping the battery and battery cells operational for a greater number of life cycles. Each EG4®-LL-S battery is specifically configured to ensure peak performance and operation with any system.
Current protection The BMS is designed to constantly monitor the charge/discharge amperage and has built-in safeguards against exceeding specific parameters. These include built-in timers that shut off quickly in the event of short circuits, extremely high amperage and delayed shut down for amperage that is only slightly above the maximum capacity.
