FAQs

Q: What size battery is ideal for kayak trolling motor?

The ideal battery size depends on the thrust of your trolling motor and how long you plan to be on the water. For most kayak trolling motors (30–55 lbs thrust), a 12V 50Ah battery or 100Ah lithium battery is sufficient. The Redodo 12V 50Ah battery is perfect for short trips, while the 12V 100Ah Mini offers extended runtime for longer adventures.

Q: Which marine battery the best for kayak​?

A lightweight, compact lithium deep cycle marine battery is ideal for kayaks. It offers high energy density, fast charging, and long cycle life—without adding unnecessary bulk or weight to your kayak.

Q: How long will a 12 volt kayak battery last?

Runtime depends on the thrust of your trolling motor or device. For example, a 12V 100Ah battery can power a 55lbs trolling motor in 50% speed for about 4 hours. Redodo lithium batteries also last over 4,000 charge cycles, far longer than traditional lead-acid batteries.

Q: Are lithium batteries better for kayak than lead-acid?

Yes! Lithium batteries are significantly lighter, charge faster, and last much longer than lead-acid. They're also maintenance-free and provide a more consistent voltage, making them a better fit for kayak.

Q: How to charge the Redodo kayak lithium batteries?

Use a LiFePO4 lithium battery charger with the correct voltage. For example, using a 14.6V charger to charge 12 volt kayak battery.

Redodo lithium batteries can be recharged using solar panels with MPPT controllers, an alternator with DC to DC charger, or a generator with battery chargers—just make sure the charging profile is designed for LiFePO4 chemistry.

Q: Is the kayak lithium battery waterproof?

Yes. Redodo kayak lithium batteries are built with IP65-rated enclosures, offering strong protection against water and dust. While they are water-resistant, they should not be exposed to water for long periods of time. It is recommended to store the battery in a dry compartment or battery box on your kayak.

Q: Can I connect two Redodo kayak batteries in parallel?

Yes, you can safely connect two Redodo 12V lithium batteries in parallel to double your capacity while keeping the voltage at 12V. Just make sure both batteries are the same model, type, capacity, BMS, and were purchased within a month before connecting.
