Review on 🔌 NOCO Genius 2X2 Smart Charger: 2-Bank, 4-Amp (2-Amp/Bank), Fully-Automatic for 6V and 12V Batteries – Battery Charger, Maintainer, Trickle Charger, Desulfator w/ Temperature Compensation by Josh Culotta

I received this for permanent installation in my RV. The goal was to set up one side for parallel AGM home batteries and the other side for liquid cell chassis batteries. In the end it works great. An extension cord to power the charger and it remembers the settings so you can't guess which is which. I installed it in the basement next to the batteries and carefully routed the wires to the batteries. Now I just plug in the charger when the RV is in storage mode. The only caveat I know of from having contacted Noco is that if the batteries are being charged from other sources (shore power, generator, alternator, etc.), you must unplug the charger (AC source). I have been told that leaving this charger plugged in while another device is charging the batteries could damage the charger. But it doesn't matter - I don't feel like constantly charging the batteries when I'm actively using the rig.
