Polinovel Bluetooth lithium battery BL series is a drop-in replacement for deep cycle lead acid batteries. It features all the advantages of lithium iron phosphate (LiFePO4) technology, delivering more usable energy, lighter weight, longer cycle life, and superior performance. The smart BMS with  Bluetooth function ensures you monitor and turn on/off the battery remotely on your phone. This series contains 12V, 24V, 36V, and 48V models available for a wide range of applications like boat trolling motors, kayaks, sailboats, bass boats, and leisure vehicles like motorhomes, caravans, camper vans, truck campers, etc.

Polinovel Bluetooth lithium batteries use top-grade lithium iron phosphate battery cells to deliver reliable power. Each lithium battery has a built-in BMS to protect against extreme temperatures, over-discharge, overcharge and short-circuits. The BMS can also balance the individual cells in the battery pack to ensure excellent performance in all deep cycle applications. Our Bluetooth lithium batteries have been widely used in marine applications and recreational vehicles like RVs, caravans, motorhomes, etc.

Utilizing a smart BMS with Bluetooth communication, Polinovel Bluetooth lithium batteries enable you to keep track of the battery's status and detect any issues through the free iPolinovel app on your smartphone. It allows you to view multiple batteries at a quick glance, helping you to monitor your battery inventory in real-time. The app's interface is easy-to-use with a minimalist design that display essential information about SOC, Status, Voltage, Current, Temperature, Cycles, and Health.

The iPolinovel app has a “Protect Battery Mode” that allows you to remotely cut off battery discharge, resulting in improved safety and performance. The wireless connection range can be more than 10 meters from the Bluetooth lithium battery.

Wireless software upgrade is available to conveniently troubleshoot battery issue. And there are current calibration and SOC calibration to ensure accurate readings. If there are discrepancies between the displayed current or SOC values and the actual values, you can easily calibrate them within the iPolinovel app, without any extra tools.

Our Bluetooth lithium batteries are designed with a reset button on the top, to restore the Bluetooth connection in case of signal loss. What’s more, we can customize different functional buttons based on specific requirements.

Our batteries have passed the IP67 waterproof test, maintaining normal voltage, no water ingress, and have a stable connection to the iPolinovel app, even after being submerged in 1-meter deep water for 30 minutes.

Our batteries have successfully endured 10 drops down 1.7-meter stairs, maintaining normal voltage and a stable connection to the iPolinovel app, with only minor impact marks.
