Review on 🚗 Nilight - 90116C 2 Gang Rocker Switch Panel with 4.8 Amp Dual USB Charger Voltmeter, Waterproof 12V-24V DC Rocker Switch for Cars, Trucks, Boats, RVs - Includes Night Glow Stickers by Rushabh Gonsales

Small enough to fit on the end of a standard plastic ammo can like those from Walmart, Harbor Freight etc. I have a small one Lithium battery used and I use it on my boat for the bilge pump and another accessory that is located at the stern of the boat. My main battery is up front and I wanted a battery in the cargo area that isn't really being used for anything else so it's always charged. The control panel works well and is easy to set up. Although it's not flexible at all. There are no built-in fuses on the hot wires, which means I should probably add one. Not shown is the minus bus that also goes there.
