Review on ⚡️ Battery Tender DC to DC Power Connector: Trolling Motor Plug for Marine 12V Power Connection - Weather-Resistant DC Plug with 80 AMP Capacity - 027-0004-KIT by Chef Deane

A very well designed and manufactured product. Costs money. I completely redid my electrical system on my small sailboat, replacing the fancy battery racks that the previous owner installed for the electric trolling motor. Installation can be a little tricky for some, but look online for installation videos. A few minor complaints are that the cable outlets could have been bigger - mainly on the battery side as I used for example 2 AWG cables and the appropriate plugs - from the batteries to the plug. Also, one of the bushings seems a little loose, but I assume it can be pushed in once the bushings are connected and tightened.
