Page 10: Brief Introduction
The state of the battery when placed into storage will affect how long it can be stored as well as the battery’s condition when it is brought out of storage. EG4 recommends that each battery is brought to a 100% SOC (state of charge) before placing it in storage. Lithium iron phosphate batteries will lose a certain percentage of their total charge while in storage, depending on how long they are stored and the conditions they are stored in. -
Page 11: Requirements For Installation
5.2.2 REQUIREMENTS FOR INSTALLATION WARNING: Before using batteries, inspect them for signs of damage. Never use damaged or puffy batteries. Please contact the distributor if a battery is received in this state or experiences this issue. • Avoid exposing batteries to conductive materials, such as water, strong oxidizers, and strong acids. -
Page 12: Installation
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. -
Page 13: Installation In Eg4 Battery Rack
Do not ground rack/cabinet or door to negative or positive bus bars! For example, in this image, there are 6 EG4-LL 12V 400Ah batteries wired in parallel. This battery bank still maintains the appropriate 12V needed for a system. However, the Amp hour rating of this bank has increased to 2400Ah. -

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. -
Page 26: Troubleshooting
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. - Page 27 HELPFUL TIP: The “Historical Record” tab can indicate what occurred with the module before entering a warning or protection state. It is recommended to export this data into a text (.txt) file to provide to the distributor for any additional troubleshooting assistance. Other Common Faults and Solutions Fault Analysis...
