Clipper Bluetooth Battery Monitor

The Clipper Bluetooth Battery Monitor (model BM-BT) solves a persistent problem for boaters and RV owners: how to monitor critical battery health without cluttering your cabin or engine compartment with wired display units. After years of running boats on everything from inland lakes to coastal waters, installing traditional battery monitors often meant drilling holes, running cables through tight spaces, and accepting a permanent fixture on your console. This wireless solution eliminates that hassle by transmitting real-time battery data directly to your smartphone, keeping you informed whether you're at the helm, below deck, or away from your vessel entirely.

The BM-BT uses Bluetooth connectivity to relay battery status, voltage, and state-of-charge information to your mobile device via a dedicated app, eliminating the need for physical cable runs or external display mounting. The monitor connects directly to your lead-acid battery bank and transmits wirelessly, meaning you avoid the common problem of corroded gauge faces, faded LED displays exposed to salt spray and UV, or cracked plastic housings from vibration and temperature swings. Its compact footprint (7 x 4 x 7 inches) fits easily in engine spaces, battery boxes, or behind panels where space is at a premium—a real advantage on center consoles, trawlers, and cruising sailboats where every square inch of console real estate is contested.

This monitor serves dual-purpose vessels and long-term cruisers who rely on auxiliary or house battery systems alongside starting batteries, as well as RV and caravan owners managing complex power architectures. The wireless transmission range allows you to check battery condition from the galley, cabin, or bridge without running to the engine room—critical when troubleshooting electrical load issues or confirming proper charging during extended anchoring. Installation requires only a direct connection to your lead-acid battery terminals and basic wiring; no invasive modifications to your boat's electrical infrastructure. Compatible with iOS and Android platforms, the Clipper Bluetooth Battery Monitor integrates into modern marine electrical management without the permanent footprint of traditional hardwired gauges.
