BATTERY INSTALLATION IMPORTANT NOTICE: Do not place battery modules on top of one another without using proper racking or cabinet solutions. For more information about appropriate enclosures, see the Enclosure Information section of this installation manual. PRE-INSTALLATION CHARGING It is required by law for lithium battery modules to be shipped at or below 50% state of charge. Therefore upon arrival, your battery may be at a low state of charge. If more than one battery module will be connected in parallel or series, it is a good practice to individually charge all batteries to a full charge...

MODULE TO MODULE CONNECTIONS Module Connection Torque: Max of 7.5 Nm (5.5 ft/lbs) MODULE CONNECTION OVERVIEW The battery modules are designed for up to 4 series or 4 parallel connections. Always use an appropriately rated cable for the voltage and current. When connecting SAE connectors, always connect to the SAE terminals. When M8 connectors, always connect to the M8 terminals. When assembling the batteries in Series or Parallel, make sure there is less than a 0.5V voltage difference between each of the battery modules. FOR PARALLEL CONNECTIONS Up to 4 modules can be connected in parallel. Connect...

We encourage you to make use of the LFP+G Google Play Store or Apple App Store application which will provide you with more detailed information than what is available to be seen on the module State of Charge “SOC” meter. NOTE: • When battery modules are connected in series or parallel, the app will connect to one battery as representative of the other batteries in the string. The information provided by the SOC meter on the battery module may be different than what is being reported on the app. If this occurs, rely on the information that is being provided by the app during high current charging...
