Buying Guide
Choosing the right lithium battery for your trolling motor can feel overwhelming, but here’s what to consider:
- Voltage: Match the voltage of your trolling motor (usually 12V, 24V, or 36V).
- Amp-Hours (Ah): Higher Ah means more run time. Consider how long you typically use your trolling motor per trip. A 100Ah battery is a good starting point for most users.
- Battery Management System (BMS): Ensure the battery has a built-in BMS to protect against overcharging, over-discharging, and short circuits.
- Cycle Life: Lithium batteries are rated for a certain number of charge/discharge cycles. Look for batteries with a cycle life of at least 2000 cycles.
- Weight: Lithium batteries are significantly lighter than lead-acid batteries. This can improve your boat’s performance and make it easier to transport.
- Warranty: A longer warranty indicates the manufacturer’s confidence in the product.
- Your Budget: Lithium batteries can range in price. Decide how much you’re willing to spend and prioritize the features that are most important to you.
FAQs
Q: Can I use a regular charger for lithium batteries?
No, you need a charger specifically designed for lithium batteries. Using a regular charger can damage the battery and reduce its lifespan.
Q: How long will a 100Ah lithium battery last with my trolling motor?
Run time depends on the trolling motor’s amp draw and your usage. As a general rule, you can calculate the approximate run time by dividing the battery’s Ah rating by the motor’s amp draw. For example, a 100Ah battery with a motor drawing 20 amps will last approximately 5 hours.
Q: Are lithium batteries safe for marine use?
Yes, lithium batteries with a built-in BMS are safe for marine use. The BMS protects against overcharging, over-discharging, and short circuits, ensuring safe operation.
Q: How do I store my lithium battery during the off-season?
Store the battery in a cool, dry place at around 50-70% state of charge. Disconnect it from the trolling motor and charger to prevent parasitic drain.
Q: What is the lifespan of a lithium battery for a trolling motor?
The lifespan of a lithium battery depends on the quality of the battery and how well it’s maintained. Most lithium batteries are rated for 2000-5000 cycles, which can translate to 5-10 years of use.
