Deep Cycle Marine Battery - The Best Marine, Automotive and Industrial Batteries

 

odyssey 31m pc2150 1mLead-acid marine and automotive batteries are a very important piece of equipment, regardless if you have a small boat that can be pulled out on dry land by hands, large vessel suitable for long off-shore fishing trips, a city car with an internal combustion engine, or you have large 4x4 SUV/truck for outdoors adventures.

Today, there are several battery types that are commonly used like Lead Acid batteries, Nickel-Cadmium batteries, Nickel Metal Hydride batteries, Lithium batteries, etc.

Non-lead acid battery types do have their advantages, but so do the lead-acid batteries and they are still the most used marine/automotive battery type.

Best 12V Kayak Trolling Motors

newport vessels kayak 55lbs w150Kayak trolling motors are lightweight and compact electric trolling motors suitable for powering kayaks and similar vessels that feature limited weight, but also payload.

Depending on the required thrust, electric trolling motors are powered by 12V, 24V or 36V DC, usually supplied by the onboard batteries, rarely by the onboard power generator. Since their required thrust is usually limited to 50-60 pounds max, kayak trolling motors are almost exclusively powered by 12V DC.
