Review on 🔋 LNEX Wireless Bluetooth 5.0 Car Battery Load Tester & Monitor | 12V 24V RV Automotive Battery Analyzer with Charger & Cranking Test | Alarm for Solar Power Systems, Boats, Cars, Trucks by Reginald Sealy

This item works as advertised. This is a simple voltage monitor with good bluetooth capabilities that connects to a smartphone. I use mine to monitor the voltage of my Titan 24V power bank in my caravan. It has a few features that I don't use with lead-acid starter batteries. One of the features not available is the ability to set trigger points for high and low voltage alarms. It has a fixed low voltage alarm point that is too low to be useful when monitoring a lithium battery, but it allows me to monitor my Titan battery's voltage from a tow vehicle, which was my main requirement. It can also store up to 30 days of voltage data, which syncs to the phone app when the phone comes within range.
