Our Slimline Smart LiFePO4 Battery combines an ultra-thin profile with advanced intelligent management systems. Unlike standard lithium batteries, it features integrated Bluetooth connectivity for real-time monitoring (voltage, temperature, state of charge), built-in Battery Management System (BMS) protection, and a compact design optimized for space-constrained applications like marine, RV, and portable energy systems. Its high energy density and lightweight structure ensure maximum power without compromising safety or performance.
The Bluetooth module enables wireless communication with smartphones or tablets via a dedicated app. Users can remotely monitor battery status (e.g., cycle count, health metrics), receive alerts for abnormal conditions (overvoltage, overheating), and adjust settings in real time. This proactive management extends battery lifespan and prevents operational failures.
Its thin form factor and smart features make it perfect for:
Marine: Trolling motors, onboard electronics.
RV/Camping: Powering lighting, appliances, and off-grid systems.
Solar Storage: Integration with residential/commercial solar setups.
Portable Power: Medical devices, mobile workshops, and emergency backups.
