The best marine battery

There are lot of marine batteries in the market. All of are not the perfect for your trolling motor. But now the question is, which battery is right choose for electric trolling motor? Or, what is the best method tochoose a perfect marine battery? Okay, nice!

We're going to give you 3 basic rules to choose the best trolling motor battery for your marine boat.

First rule:

Do not use a car starter battery for your trolling motor. Starting batteries are designed to deliver the stored energy in short bursts of high current that are made so much spaced. If a starter battery we request delivery of egg 25 A continuously, the battery will not be able to deliver the energy that has accumulated (ampere-hour) as this delivery continued the "suffocation" after a while. Use deep cycle batteries, if possible AGM technology, designed for this type of work. These batteries themselves will be able to deliver the requested amperage during the scheduled time and will last many charge-discharge cycles.

Second rule:

Calculate amps consuming engine, with the following formula: Push in pounds / Motor Voltage x 12 = Amperes consuming.

For example:

55 pounds of thrust / 12 x 12 = 55 Volts Amperes

55 pounds of thrust / 24 x 12 = 27.5 Volts Amperes

55 pounds of thrust / 36 Volts Amperes x 12 = 18.3

Note: Although we have an engine of 55 pounds of thrust, probably we will not continually use 100% power, so we estimate the average power used%.

Third rule:

Depending on the number of consecutive hours that you want autonomy, select the required battery.

For example:

With an engine that consumes 55 Amperes, we will use an average of 75% of its power, we want an autonomy of 3 hours. Battery needed = consumption power amps x% x operating hours x 1.3 = 55 A x 0.75 x 1.3 x 3 h = 160,88 Ah.

Fantastic. To take a walk of 3 hours with an electric trolling motor we have to buy a 160-amp battery deep discharge, which is worth a small outboard motor.

Choose deep cycle marine batteries

Use a deep cycle battery configuration, where a separate starter battery is used to start the engine, and actual cycle battery is used for accessories. This configuration is ideal for boats with larger engines, which need a lot of energy to start early. A free starter battery power faster, and thus exhausts its stored energy quickly, to provide the output amperage for snacks high amounts of energy. Power is supplied then the deep cycle battery accessories, while the battery recharges to leave for the next time it is needed.

Use a single deep cycle battery for smaller boats with small motors or boats operated drive motors. Small motors do not require a lot of electricity to start, and traction motors do not require electricity boot. In this case, a deep cycle battery will provide power to start a small engine and still provide enough energy to power the drive motors and accessories.

Use a deep cycle battery hybrid that has the attributes of both a starter battery and a battery deep cycle really means for the engine with electric start and accessories on board, or if space is at a premium. These batteries have two types of plates inside. One type of power outputs for fast engine starting, and the other plates slowly release energy to power accessories.

Choose a gel battery or battery-SVR AGM for maximum efficiency, zero maintenance and long runs. This type will cost more than a lead-acid battery reference, but give better performance, faster loading, unloading, except when sitting idle, and completely sealed to eliminate acid spill.
