Battery Monitor with Bluetooth — Energy Monitor, JUNCTEK

This JUNCTEK battery monitor is for the DIY enthusiast or RV owner who needs to track power usage accurately. Instead of just measuring numbers, it gives you control over your battery's health, whether you're managing a solar setup or ensuring your boat doesn't run out of juice.

The Bluetooth app lets you check real-time data from your phone, so you can see discharge rates before a trip without guessing. The self-calibration keeps readings precise over time, and the pure copper components minimize heat loss. With protection features like over-voltage alerts, it helps prevent damage, making your system more reliable.
