Marine Boats
Kickstarts Your Ocean Exploration Journey
Choosing the right deep cycle marine battery depends on your boat's size, power requirements, and your usage. For small boats, you can choose 12V 100Ah series batteries. For larger boats, WattCycle recommends you choose 12V 200Ah - 280Ah. WattCycle's high-capacity batteries meet your various marine needs.
Lithium Marine Battery Types
It is important to understand the different battery types and their functions for choosing the right deep cycle marine battery.
Lithium Marine Starting Battery (Cranking Battery)
This battery provides the quick surge of energy needed to start your boat’s engine. Designed for reliability, it ensures your engine starts smoothly, even in challenging conditions.
Lithium Deep Cycle Marine Battery
Designed for steady, long-term energy delivery, this battery is perfect for powering trolling motors, fish finders, GPS systems, audio systems, and other electronics. It can be discharged and recharged multiple times, providing reliable, long-lasting power for extended boating trips.
Dual Purpose Lithium Marine Battery
This battery is capable of both starting the engine and powering onboard systems, making it ideal for boats with limited space.
WattCycle’s deep cycle marine battery belongs to the second category - Lithium Deep Cycle Marine Battery, which is specially designed to power systems on board ships.
Deep Cycle Marine Battery: AGM Batteries Or Lithium Batteries?
When chossing deep cycle marine batteries for your boat, there is always a question of whether to choose AGM batteries or lithium batteries. It's important to consider each option's performance, durability, and long-term value.
- AGM Deep Cycle Batteries: AGM batteries are known for their durability and low maintenance, making them a popular choice in marine environments. However, they tend to be heavier and have a shorter lifespan compared to lithium batteries. With a limited depth of discharge (DOD) of around 50%, AGM batteries require more frequent charging, reducing their overall efficiency over time.
- Lithium Deep Cycle Batteries: Lithium deep cycle marine batteries offer numerous advantages. Their significant advantages are that they are lightweight, long-lasting, and can be discharged up to 90% or more without any negative impact. Even some of lithium deep cycle marine batteries are built-in Bluetooth, giving you real-time monitoring of your battery’s state with ease. These batteries recharge faster and require minimal maintenance, making them ideal for boaters seeking reliable, long-term power.
If you have limited space on your boat and require a lighter battery, then the lithium deep cycle marine battery is your best choice. If you have a very large boat and a limited budget, AGM deep cycle marine batteries are also the best choice.
Real Stories About WattCycle Deep Cycle Marine Battery
Know More About Deep Cycle Marine Battery Information
What is a deep cycle marine battery?
Engineered to provide consistent, long-lasting power over extended periods, deep cycle marine batteries are ideal for powering trolling motors, navigation systems, and onboard electronics. These deep cycle batteries can withstand deep discharges and repeated recharges without degrading quickly, offering exceptional longevity.
Are all marine batteries deep cycle?
Not really, but most marine batteries are designed as deep cycle batteries due to their ability to handle prolonged energy usage. The right deep cycle marine battery is essential for boaters who need reliable power over extended periods.
How long will a marine battery last?
The lifespan of a marine battery depends on multiple factors like frequency of use, charging method, and battery type. If you choose to use a lithium deep cycle marine battery and with proper maintenance, you can use it for more than 10 years. Our batteries use EV grade A+ LiFePO4 cells and advanced BMS, which can support 5000 - 15.000 cycles and 100% DOD.
What is a marine battery used for?
As mentioned in the text above, marine batteries are roughly divided into three categories: cranking battery, lithium deep cycle marine battery, and dual-purpose battery. Cranking batteries are mostly used to start engines; lithium deep cycle batteries are used to run electronics; dual-purpose batteries not only start engines but also run electronics (ideal for small boats with limited space).
Do marine batteries need maintenance?
Depends on the type of marine battery you choose. If you choose WattCycle lithium deep cycle marine batteries, then there is almost no maintenance required; if you choose AGM batteries or GEL batteries, then you will need to perform regular maintenance.
Can I use a deep cycle marine battery for both starting and powering electronics?
Unfortunately if you want to start the engine and power your equipment at the same time, a deep cycle marine battery won't do it. If you have this need, WattCycle recommends that you choose a dual-purpose battery.
What is the best way to charge a lithium deep cycle marine battery?
WattCycle recommends 3 charging methods: AC - DC LiFePO4 battery charger, Solar panel with solar controller, and DC generator with DC - DC charger. If possible, WattCycle recommends using an AC-DC LiFePO4 battery charger.
Deep cycle battery or dual purpose battery which is good for your boat?
This depends on the space you have for placing batteries on your boat and the purpose of the batteries. If your boat has a lot of space and you need batteries to start the engine and power your equipment, WattCycle recommends that you buy cranking batteries to start the engine and lithium deep cycle marine batteries to power your equipment; if your boat has limited space and the above needs also exist, then it is recommended to choose dual-purpose batteries.
