A Classic Choice, A High-Performance Product-CoPow 12V 100Ah Marine Lithium Battery.
There are many 12V 100Ah marine batteries available on the market, so why choose CoPow? Here's why:
1. Longer Service Life
Equipped with high-quality lithium iron phosphate cells from CATL, the battery has a cycle life of over 6,000 cycles and a service life of more than 8 years.
2. Lighter Weight
They weigh more than half as much as lead-acid batteries, thereby reducing the boat's load and freeing up more kinetic energy.
3. Higher Usable Capacity
The actual usable capacity is 30% greater than that of lead-acid batteries, allowing for the use of approximately 90% of the battery's charge-close to the rated capacity.
4. Stable Voltage Output
From 100% battery charge to 50%, and then to 10%, power remains ample and the voltage remains stable.
5. Faster Charging
It takes only 1–3 hours to fully charge.
6. Apply protective treatments to the materials-fully equipped from top to bottom.
Our 12V 100Ah lithium-ion marine batteries undergo special treatment from the inside out-from the casing to the screws-reaching near-military-grade standards. Protection ratings include IP65, IP67, and IP68, and materials range from 316 stainless steel
to anodized aluminum alloy; the casing material can also be selected according to your needs.
7. Intelligent Battery Management System
This system not only provides basic protection functions such as overcharge, over-discharge, overcurrent, short circuit, and high/low temperature protection, but also supports high-precision SOC calculation, active cell balancing, charge/discharge data logging, fault diagnosis and early warning, as well as multi-level safety protection strategies.
In addition, depending on project requirements, advanced features such as a Bluetooth app, CAN bus, RS485, NMEA 2000, GPS remote monitoring, 4G IoT management, self-heating control, and remote power on/off can be optionally configured to make vessel energy management even smarter.
8. Save Time
No more wasting time on battery maintenance, leaving you with more time to enjoy sailing.
9. Low-Temperature Performance
Lead-acid batteries experience issues such as reduced capacity and insufficient power in low-temperature environments, whereas CoPow's lithium iron phosphate marine batteries maintain good performance even at low temperatures and are virtually free of these problems.
10. We offer both starter batteries and deep-cycle batteries.
Our marine batteries can serve not only as starter batteries but also as deep-cycle batteries. Whether you need a marine battery that can reliably start your engine in cold weather or one that can provide long-term power to your onboard equipment, we can customize a solution for you.
11. Safety
The lithium iron phosphate chemical system has excellent thermal stability and does not produce oxygen; therefore, it will not cause a fire or explosion. Please feel free to use it with confidence.
12. High Level of Customization
CoPow can customize capacity, voltage, dimensions, enclosure design, communication protocols, protection ratings, self-heating functions, and brand appearance based on different vessel types and project requirements to meet the personalized needs of OEMs and professional marine customers.
