Introduction
Batteries for trolling motors are made specifically for use with boats. They are designed to offer electricity for a longer duration when slowly cruising through fishing grounds.In contrast, the ignition is started using boat starting batteries. With marine batteries, the engine must be started before there is enough power to support the motor and any attached gadgets. It's quite unpleasant if your trolling motor battery dies while you're out on the lake because a strong battery is necessary to maintain your trolling motor operating consistently.
It's critical to understand how long your trolling motor battery will last and how to extend its life in order to prevent battery issues.
Electric Trolling Motor Battery Life
Lead Acid Wet-Cell and AGM Batteries were the two main deep-cycle 12-volt batteries that were advised for use with trolling motors for a long time. The phrase "Deep-cycle" denotes that the batteries are made to be recharged more frequently and for longer periods of time while discharging lower quantities of current. Although lithium batteries are starting to gain traction, "conventional" batteries are still by far the most common trolling motor batteries.
How long will this motor last on the water? is a popular query when attempting to choose a motor. The amperage hour rating of a battery and the amperage draw of a motor are two things that must be understood in order to respond to this issue. Although estimating the run time of a trolling motor is not an exact science, the following parameters can aid in your estimation.
Amperage Hour Rating
Marine batteries are rated according to a standard known as "amperage hours," which shows how long a battery can supply a constant amperage. With a higher rating, the battery can store more energy and run a motor at a specific speed for longer periods of time. As an illustration, a battery with 100 amp-hours of capacity may power a device at 25 amps for four hours (25 amps multiplied by four hours equals 100 amp hours). As an alternative, the same battery might deliver 10 amps of power for 10 hours (10 amps multiplied by 10 hours equals 100 amp hours) before it runs out of juice. The amperage hour rating can be compared to a car's gas tank: the bigger the tank, the more energy it can hold and the longer it can run a motor.
Motor Amperage Draw:
Motor amperage drain is the second aspect we must consider when calculating expected run time. The amount of amperage (or current) a motor draws at a specific speed is referred to as the motor's amperage draw rating. Take the battery's amp hour rating and divide it by the amperage draw to get an idea of how long a particular motor will operate on the water. For instance, the runtime for a motor that draws 20 amps at medium speed and is powered by a 100 amp-hour battery would be:
100 ampere hr rated battery / 20 ampere draw = 5 hr run time
You might need to estimate additional amperage draws at different speeds using the highest speed amperage drain as a baseline as the majority of manufacturers only mention a motor's maximum amperage draw at top speed.Please keep in mind that these are simply estimates, and final results will depend on the precise motor specifications, batteries utilised, and water conditions.
Electric Trolling Motor Battery Size
There are many distinct battery kinds, such as starter batteries, dual-use batteries, deep-cycle batteries, etc., as well as several "group sizes" and various voltage outputs.
Size of Battery: Voltage
Every trolling motor is made to operate on a 12V, 24V, or 36V system. Although there are single batteries available that are rated for 24V or 36V, most anglers use a single 12V battery or, if necessary, two or three in parallel.
Trolling motors that produce less than 55 pounds of thrust often just require a single 12V battery. Expect to power them with two 12V batteries when you increase the power to motors with up to 80 pounds of force. And you usually need three 12V batteries to power the most potent trolling motors, which can generate more than 80 pounds of torque.
less than 55 pounds of thrust = 12 volts (one battery)
24 volts = 68–80 lb of thrust (two batteries)
36 volts =101–112 pounds of thrust (three batteries)
Remember that a trolling motor won't become more powerful by adding more batteries. And utilising fewer batteries will, at best, significantly reduce power.
Sadly, maximum dimensions for a Group Size don't indicate real measurements, and battery makers frequently disregard these "guidelines." Even worse, in practise, batteries belonging to a Group may not fit at all in a place designated for them due to size variations. you should always measure the batteries and never rely on the Group Size to guarantee a satisfactory fit.
Electric Trolling Motor Battery Charger
Finally, you must select a charger that is appropriate for your Outdoorbox or Battery. There are two questions you should determine for yourself, albeit the options differ depending on the battery:
Is waterproofing a requirement for the battery charger?
How quickly do you want your battery to charge?
The initial query is obvious. If you usually keep the battery charger indoors and charge your batteries there? You can then choose a "standard" battery charger. We advise a waterproof charger, though, if you also want to be able to charge the battery on board and permanently put the charger in your boat. You frequently have the choice between a standard charger and a fast charger as well. A standard charger will do if you always use your boat for a few hours and have the option of charging it overnight for your upcoming (fishing) trip. A rapid charger, however, might be the answer if you want to use the boat for the entire day and recharge during lunch. On the product pages of our chargers, you may find details about the charge speed.
