Tired of surprise dead batteries? Want to keep tabs on your vehicle or solar system’s power health? Meet the LNEX Bluetooth Battery Monitor — your new best friend for battery peace of mind.
This little device connects to your 12V or 24V battery and pairs with your smartphone via Bluetooth 5.0. That means faster data transfer, longer range, and minimal power drain on your battery. You can check voltage, charging status, and overall battery health right from an app on your phone.
It’s packed with useful features: starting system tests, alternator load checks, driving time logs, and even customizable low-voltage alarms. You’ll get notifications if your battery level drops too low, so you can recharge before you’re stranded.
Installation is straightforward — just connect the wires to your battery terminals (with reverse polarity protection, so you can’t hook it up backward). It works with all kinds of batteries: flooded, AGM, GEL, EFB, and more.
Perfect for cars, trucks, RVs, motorcycles, boats, travel trailers, and even off-grid solar power systems. Whether you’re a weekend camper, daily commuter, or solar enthusiast, this monitor helps you avoid unexpected power failures.
With safety features like short-circuit protection and long-term data storage (up to 30 days), you can monitor trends and catch issues early. No more guessing if your battery is good — now you’ll know!
Stay powered up and stress-free. The LNEX Battery Monitor is a smart, affordable way to protect your battery and your plans.
