Best use case: Best suited for installations where the charger and battery bank are in close proximity β€” such as a console or under-seat compartment β€” and only a short extension is needed. For longer runs to bow, stern, or remote battery locations, recommend the 15 ft version (175-51815) instead. Confirm the customer’s charger output does not exceed 30A before recommending.
