    High-performance dual purpose lithium battery for marine boats, cars, trucks, RVs, ATVs, etc.

Lithium Dual Purpose Battery

Polinovel DUAL series are high-performance dual purpose lithium batteries for starting and deep cycling. 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, ATVs and many other applications that need sufficient power to start the engine and run smoothly.

Product Features

Powerful Performance

Polinovel uses premium lithium iron phosphate cells, the pure copper current board, and high-quality cable to manufacture DUAL series lithium batteries. Combined with a strong and heat-dissipative internal structure design, we ensure the safe and reliable operation of starting power. We use equalizing charging board to ensure the consistency of the long-term use of our batteries.

Polinovel LiFePO4 Battery Cells

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.

Polinovel Battery Status Monitoring

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.

Polinovel Dual Purpose Lithium Battery Bluetooth Function

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.

Polinovel Lithium Battery Waterproof Resistance

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.
