Polinovel BL Series lithium battery is the direct replacement of deep cycle lead-acid batteries. It uses automotive-grade EVE LiFePO4 cells with low internal resistance, high consistency and sufficient capacity. In addition, this 12V 105Ah lithium battery is equipped with a current limiter to ensure safe parallel connection with lead-acid batteries.
Polinovel BL Series lithium battery is equipped with a smart BMS with Bluetooth connectivity for real-time battery status monitoring on smartphones via iPolinovel app.
The app boasts a user-friendly interface and a minimalist design to ensure easy access to vital battery information. You can view multiple batteries at one glance, and get detailed data like SOC, Status, Voltage, Current, Temperature, Cycle Times, and Battery Health, for a comprehensive view of battery performance.
A unique protection mode is available to easily cut off battery discharge. What’s more, there are wireless software upgrade to help troubleshoot battery issues, and calibration function to directly calibrate current and SOC without extra tools.
Normally, when some lithium-ion batteries’ voltage fall below the BMS operating voltage, they can’t be charged, and are often discarded as ‘dead’, which is wasteful. Polinovel’s innovative Reset button can boost those dead batteries back to life. Simply press the button to bypass the BMS to enable immediate charging, and activate the batteries.
Plus, the Reset button can be used to restore the Bluetooth connection in case of signal loss. This smart button ensures a stable power supply and seamless Bluetooth connection.
This LiFePO4 battery has IP67 waterproof resistance and exceptional shock resistance. It is the ideal solution for marine boats, RV motorhomes, and other applications exposed to wet conditions or rough vibrations.
To guarantee its reliability, Polinovel has conducted rigorous tests. Our battery has been submerged in 1-meter deep water for 30 minutes, and dropped from 1.7-meter stairs for 10 times. After the tests, the battery maintained normal voltage and a stable Bluetooth connection.
