Nilight 12V 140 AMP Dual Battery Isolator Auto Manual Voltage Sensitive Relay with Digital Voltmeter Smart VSR Automatic Charger Disconnect w/Voltmeter for Truck RV UTV Boat Can Am

Works Good

Muy bien

I fitted this Isolator to a 35 ft Bruno Commercial Fishing Boat with a Cat Marine Engine with 2 4D Batteries for the Engine, and a 4D House Battery! I installed the Isolator on Sunday the 24th February 2025, and it worked Perfectly! The Boat Owner went Fishing on Monday, and called me up when He returned in the evening and said that the Voltmeter on the Isolator went off when he was pulling in his Lobster Pots with the hydraulic winch, but was still able to pull all of the pots! He thought that the Isolator failed! He didn't check the House Voltmeter on the Panel, just the Engine Voltage on the Instrument Panel! I think checked the Isolator after starting the Engine, and it worked Perfectly, despite fact that the Voltmeter wasn't lighting up, but the single LED light showing that the Isolator was connecting with the Engine Battery and Still Charging the House Battery, because it was Fully Charged when I checked it!

Excelente cumple con su función

Before you began installation place things where you think they need to go. Then imagine where you can hide wires so as not to getting stepped on etc. I was fortunate enough to already have a crumpet for the 6ga wire and ends for this. As of yet-not a problem, it works as it ways it would-charging both batteries

Got this for a duel battery system on a vehicle. I'd used a much more expensive brand on my primary truck and got this one for my second to compare and I found them to be almost identical in form and operation to one costing almost 100. Would recommend.

this is a great product and easy to install. but be careful the plastic is fragile.
