Key Factors to Consider When Choosing a Lithium Battery
1. Energy Requirements
Understanding your energy needs is crucial. Calculate your daily consumption to determine how much power you will require. This helps in selecting a battery that can adequately meet your demands without overloading the system.
Calculate Daily Consumption: Use the formula:
Daily Consumption (Wh) = Wattage (W) × Hours Used Per Day
For example, if you have a LiveScope fish finder, the LiveScope work current is 4.8A for 10 hours (at 12V), so your Consumption is 4.8A×12V×10h=576Wh
2. Capacity
Battery capacity, measured in ampere-hours (Ah), determines how much energy the battery can store.
AH = Work Current(W) × Hours Used Per Day
For example, if you have a LiveScope fish finder, the LiveScope work current is 4.8A for 10 hours (at 12V), so your Consumption is 4.8A×10h=48AH，so you can choose 12V 50AH LiFePO4 battery.
3. Voltage Compatibility
Ensure that the battery voltage aligns with your devices. Most setups utilize 12 volt deep cycle batteries, which are ideal for recreational vehicles, solar systems, and more. If you need higher voltage, you can connect 12V LIFEPO4 batteries in series. For instance, to get a 24V 100AH system, connect two 12V 100AH batteries in series. For a 48V system, connect four 12V batteries in series. Check out WattCycle’s Series Parallel guide for clear, step-by-step instructions on how to connect your batteries properly.
4. Size and Weight
A compact design is essential, especially for RV and camper van. Group 24 deep cycle batteries offer a lightweight alternative, making transportation and installation easier without sacrificing energy density.
WattCycle 12V 100Ah LiFePO4 battery Compactly designed at 10.2 x 6.6 x 8.2 inches (26 x 17 x 21 cm) and weighing nearly 2/3 lighter (23.0 lbs / 10.5 kg) than a lead-acid battery, this lithium battery fits seamlessly into a Group 24 battery box, maximizing energy density without requiring a larger box.
5. Depth of Discharge (DoD)
The depth of discharge indicates how much of the battery's capacity can be utilized. A higher DoD allows for more efficient energy usage, maximizing performance without compromising battery life. Wattcycle lithium batteries provide up to 15,000 charge cycles and up to 5,000 cycles at 100% DOD.
6. Cycle Life
Cycle life refers to the number of charge-discharge cycles a battery can undergo before its performance declines. Lithium batteries typically offer a longer cycle life, making them a more durable option for users. A typical lead-acid battery may last between 2-3 years, but WattCycle’s LiFePO4 batteries can support up to 5,000 cycles at 100% depth of discharge, translating to around 10-15 years of use.
7. Safety Features
Safety is paramount. Look for batteries equipped with features like overcharge protection and thermal management. Built-in Battery Management Systems (BMS) help monitor battery health and prevent issues.
8. Water Resistance and Durability
Consider the environmental conditions where the battery will be used. Waterproof ratings ensure reliable performance in challenging environments, making these batteries suitable for outdoor use.
Application for Lithium Deep Cycle Batteries
Each application for a deep cycle battery comes with its own specific energy needs, influencing the choice of battery. Here are some common scenarios:
1. Trolling Motors
For fishing enthusiasts, a lithium battery specifically designed for trolling motors provides reliable power and longer run times. The 12V 100Ah deep cycle battery offers efficient energy for motors with thrusts between 30 to 70 lbs, enhancing your experience on the water. Featuring IP67-rated protection, this battery is resistant to water, dust, and salt spray, making it suitable for wet and dusty environments, enhancing durability and reliability.

3. Fish Finders
Using a dedicated battery for your fish finder ensures optimal performance throughout your fishing trips. These devices often require consistent power, making lithium deep cycle batteries a smart choice for reliability and longevity.
4. Golf Carts
Golf carts equipped with lithium batteries enjoy reduced weight and longer life cycles compared to traditional lead-acid options. This allows for increased range and performance on the course, with the 12V 100Ah deep cycle battery being an ideal fit.
5. Marine and Boat Applications
Marine environments demand batteries that can withstand harsh conditions. With above IP65-rated waterproof features, lithium deep cycle batteries offer durable, reliable power for lighting, navigation, and other essential functions on boats and yachts.
