High-performance Dual Purpose Battery Solutions

Polinovel, a leading lithium battery pack manufacturer in China, provides a range of dual purpose lithium batteries for both cranking and deep cycle applications. Our dual purpose batteries use LiFePO4 chemistry to ensure high safety, light weight and a long lifespan. With high starting currents and consistent power output, they are ideal for use in cars, marine boats, trucks, and many other applications that need sufficient power to start the engine and run smoothly.

Advantages of Polinovel Lithium Dual Purpose Batteries

Reliable LiFePO4 Battery Solution

Polinovel DUAL series lithium batteries use Grade-A lithium iron phosphate cells for great durability. Each battery is equipped with a state-of-the-art BMS that provides multiple protections against overcharging, over-discharging, over-current, short circuits, etc. Additionally, the BMS features Bluetooth connectivity to ensure real-time battery status monitoring.

Optimal Dual Purpose Battery for Starting and Deep Cycling

Polinovel DUAL series lithium batteries offer both a powerful burst of current for starting, as well as a constant and stable power supply for extended use. They provide a perfect balance between starting engines and deep cycling. Ideal for use in cars, trucks, and marine applications like yachts, bass boats, sailboats, etc.

Easy Battery Status Monitoring

Using a smart BMS with Bluetooth communication, Polinovel DUAL series lithium batteries enable you to monitor the battery's status and detect any issues through the free iPolinovel app on smartphones. The app is easy-to-use with a minimalist design that allows you to view multiple batteries at a quick glance and get essential battery information like SOC, Status, Voltage, Current, Temperature, Cycles, and Health.

Protection Mode to Enhance Safety

The iPolinovel app features a “Protect Battery Mode” that allows you to remotely cut off battery discharge, for improved safety and performance. The wireless connection range can be more than 10 meters (32 feet) from the battery.

Practical Functions for Better Battery Management

Wireless software upgrade is available to troubleshoot battery issue. And there are current calibration and SOC calibration to guarantee precise readings. If the displayed current or SOC deviates from the actual value, you can easily calibrate them in the iPolinovel app without using extra tools.

Functional Buttons for Maximum Performance

Our dual purpose lithium batteries are designed with a reset button on the top to restore the Bluetooth connection in case of signal loss. There is also an emergency switch to jump-start the engine if the battery is out of power. What’s more, we can customize more functional buttons to meet specific requirements.

IP67 Waterproof Resistance

Our batteries have undergone the IP67 waterproof test, maintaining normal voltage, zero water ingress, and a stable connection to the iPolinovel app, even after immersion in 1 meter deep water for 30 minutes.

Superior Shock Resistance

Our batteries have demonstrated exceptional shock resistance, enduring 10 drops down 1.7 meter stairs with only minor impact marks, while maintaining normal voltage and a stable connection with the iPolinovel app. These batteries are ideal for applications that may encounter intense vibrations.
