This Product is ONLY an addition on Electric Outboards like the EPropulsion Navy 3.0 & 6.0 where we remove the Amphenol Sur-Lok Connectors used by their proprietary battery and properly install marine-rated Tinned Copper Ring Terminals for use on a 3rd Party Battery. Such as your own or our highly reccomended EPOCH 48V 100ah Lithium or PowerHouse 173ah Batteries.
