What Are The Advantages Of The CoPow 24V 100Ah Lithium Marine Battery?
The 24V 100Ah battery is a very popular choice, and CoPow has specially designed this model:
1. Longer Service Life
Equipped with high-quality LiFePO4 battery cells from CATL, these batteries can withstand over 6,000 charge-discharge cycles, ensuring a stable service life of 8 to 10 years.
2. Lighter Weight
For the same 100Ah, 24V capacity, lithium-ion batteries are 35–45 kg lighter than lead-acid batteries, representing a weight reduction of 50%–70%. This not only makes handling easier but also reduces the load on the hull, frees up more power, extends runtime, and prevents the waste of significant amounts of power caused by bulky lead-acid batteries.
3. Stable Voltage Output
CoPow's 24V 100Ah lithium-ion battery utilizes LiFePO4 technology, which ensures a smoother voltage plateau during discharge. Even as the charge level drops from 100% to 50% and then to 20%, it continues to deliver a stable voltage output.
4. Multiple Protection Ratings Available
CoPow offers a range of protection ratings-including IP65, IP67, and IP68-to suit different marine application environments.
5. Intelligent Low-Temperature Heating Function
Our marine batteries also feature an intelligent low-temperature heating function. When the Battery Management System (BMS) detects that the cell temperature is below the safe charging range, the system first activates the heating film and begins charging only after the cell temperature has risen to an appropriate range.
6. Bluetooth Smart Monitoring
Users can view the battery's SOC (State of Charge), voltage, current, temperature, cycle count, and fault status in real time via their smartphones.
7. Faster Charging Speed
Our lithium-ion marine batteries support more efficient constant-current, constant-voltage charging. Compared to traditional lead-acid batteries, lithium-ion batteries can withstand higher charging currents, making the charging process more efficient. While traditional lead-acid batteries typically take 8 to 12 hours to fully charge, a 24V 100Ah lithium-ion battery can be fully charged in just 1 to 3 hours.
8. Easy Battery Maintenance
You no longer need to worry about checking the electrolyte, topping up water, cleaning terminals, performing equalization charging, or dealing with acid leaks, corrosion, and sulfation issues. The CoPow 24V 100Ah lithium-ion battery features a sealed lithium iron phosphate (LiFePO₄) design that requires no water top-ups and eliminates the risk of acid leaks.
The built-in BMS automatically provides charge/discharge protection, overcurrent protection, short-circuit protection, temperature protection, and cell balancing, making the battery even more worry-free in daily use.
9. Actual Capacity Close to Theoretical Capacity
Our lithium-ion marine batteries support a depth of discharge (DOD) of 90% or higher, capable of consistently delivering an actual capacity of over 90Ah without compromising battery life.
10. Superior After-Sales Service
We offer a 5- to 10-year warranty on our marine batteries. During this period, if you encounter any issues, you can contact your dedicated account manager directly, and we will promptly resolve the problem for you.
