The E360 400 A Extended Aluminum Bus Bar Set is designed to parallel connect the E360 group 24 and 27 model lithium batteries to create a higher capacity battery bank. The bus bars fit precisely on the E360 60, 80, 95, 100, and 120 Ah battery terminals to make the best electrical connection possible, lowering resistance and increasing efficiency. The extended bus bars connect two dual battery tie-down tray systems to build a quad-battery bank. The extended bus bars are also used to connect single battery trays when the E360 external heating system is installed. Single trays and extended bus bars are required to provide space between the batteries when using the E360 external heating system and the tie-down tray system together. Spec Sheet
