24v 50Ah Lithium Ion Battery

Enjoy the Best Boating Experience at the Lowest Cost with CoPow 24V Lithium Marine Batteries.

Take your favorite little boat out for a spin-no need to worry about battery issues anymore.

1. Marine-Grade Protection

Unlike marine batteries converted from energy storage batteries, CoPow marine batteries are designed from the ground up specifically for marine environments. They feature salt fog resistance, IP67-rated waterproofing, moisture-proof sealing, and vibration resistance, providing 360° all-around protection for the battery and ensuring reliable operation even in windy and rainy weather.

2. Small Battery, Big Power

It delivers ample power while reducing weight. Compared to a 50Ah lead-acid marine battery, the lithium-ion battery is 50% to 70% lighter, weighing just 12.7 kilograms.

3. Fast Charging

It can be charged from low to full capacity within 1–3 hours. Even if you decide to go out on a whim and the battery is dead, you can quickly recharge it to take advantage of good weather for a boat trip.

4. Customizable Design

Feel free to share any ideas with CoPow. We offer a wide range of customization options-including capacity, dimensions, exterior colors, brand logos, communication protocols, Bluetooth apps, and displays-to help you quickly create a product tailored to your needs.

5. Premium Grade A Cells

We use Grade A lithium iron phosphate cells from brands such as CATL, EVE, and BYD, with a cycle life exceeding 6,000 cycles and a stable service life of over 8 years.

6. Intelligent Battery Management System

CoPow's Battery Management System not only provides basic protection functions-such as overcharge, over-discharge, overcurrent, short-circuit, high-temperature, and low-temperature protection-but also features high-precision SOC calculation, active battery balancing, charging/discharging data logging, fault diagnosis and early warning, as well as multi-level safety protection strategies.

Depending on project requirements, additional specialized functions can be added to ensure the BMS fully fulfills its protective role.

7. Low-Temperature Adaptation

CoPow lithium-ion marine batteries are equipped with an intelligent self-heating system. When the ambient temperature falls below a preset value, the battery prioritizes using electrical energy from the charger to heat the battery cells. Once the cell temperature rises to a range suitable for charging, the battery will begin charging normally. Additionally, the battery does not experience significant capacity degradation in sub-zero Celsius environments.

8. Time-Saving

Lithium-ion batteries require no water top-ups and eliminate the need to clean battery terminals corroded by electrolyte, offering a simpler and faster maintenance routine. In most cases, all you need to do is check the battery's operating status.

9. Balancing Starting and Deep Cycle Performance

Our marine batteries include both starting and deep-cycle series, as well as dual-purpose series, allowing you to choose freely based on your needs.

10. Safe and Stable

Out on the open sea, you don't have to worry about the battery suddenly catching fire or even exploding. What you're carrying isn't a time bomb, but a high-quality marine battery that ensures your safe journey to and from your destination.
