4.2.2 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.
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). Keep the battery away from locations where it may get wet or locations with high humidity (>55%). Store the...
5.2.2 Requirements for Installation Warning Do not put EG4® 48V-LL 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 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.
5.3 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.

This protection also aids in keeping the battery and battery cells operational for a greater number of life cycles. Each EG4®-LL 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.
There are several websites and organizations that will accept this battery to recycle at little to no cost to the user. At EG4®, we understand that we are working with customers across the United States and the world. Our recommendation is to go online and search the...
