The 12.8V 50Ah Bluetooth Lithium (LiFePO4) Battery is a high-performance power supply engineered for versatile applications, including RVs, off-grid energy storage, trolling motors, and portable power systems. Built with long-lasting prismatic cells, it delivers 640Wh of reliable power and offers a lifespan of over 3,000 cycles.
Key Features
- Smart Bluetooth Monitoring: Wirelessly connects to a dedicated mobile app to provide real-time tracking of State of Charge (SOC %), voltage, output current, internal temperature, cell voltages, and total cycle count.
- Integrated 50A BMS: Features an advanced Battery Management System supporting up to 50A continuous charge/discharge current (640W continuous load capacity) with a 90A peak output for up to 5 seconds.
- Weatherproof & Rugged Design: Enclosed in a heavy-duty, IP67-rated ABS plastic shell designed to resist water, dust, and harsh environmental conditions.
- Versatile Charging Options: Compatible with solar panel controllers, standard 12V LiFePO4 chargers, and alternator/generator setups.
- Expandable & Compact: Supports up to 2 batteries in series (for a 24V 50Ah system) or 2 in parallel (for a 12V 100Ah system). Compact dimensions (9.0″ L × 5.4″ W × 8.4″ H), an integrated carrying handle, and M6 terminal posts ensure quick, hassle-free installation.

This item is a very good price especially with free shipping. I just bought more of them. I plan on using them in our camper and in my boat. Have not had much time to try them out at but after I downloaded the app they appear to be in very good condition. Thanks,
