The Different Types Of Batteries: Cranking, House, & Trolling Motor Batteries
When choosing your charger youāll need to think about chemistry, voltage, and capacity. Youāll also need to consider what youāre charging as well. Maybe your setup is pretty simple and all you need to power is your engine and trolling motor. Or maybe youāre all about the accessories, and on top of the typical setup, you need to power a fish finder, CD player, extra lights, and more. Either way, we have a variety of marine battery chargers to help you get the job done right!
Before you settle on the best marine battery charger, letās first discuss a few of the battery types you may have on board.
A Cranking Marine Battery
To start your engine youāre going to need a āstartingā battery. A lot of times this battery is also called a ācrankingā battery. This battery is designed to give a short and powerful burst of energy to fire up your engine. The purpose is to turn your engine over. Depending upon how much youāre powering on your bass boat, you may have one single battery dedicated to this job. Unless your boat is extremely small, expecting a cranking battery to power up your engine and all of your accessories is a really big ask. Now the cool thing about starter batteries is that they generally receive a charge while your boat is running. A lot like a car battery. But that doesnāt mean youāll never charge your starter battery.
Deep Cycle Batteries
Most boaters have a deep cycle battery or āhouse batteryā on board. Oftentimes, more than one battery is connected in series or parallel to supply all your power needs. Many refer to these types of batteries as the āmarathon runnersā. They exist to power equipment or gadgets that require more constant charge. Think lights, audio systems, fish finders, navigation tools, and more. These batteries need to be charged frequently, especially if you use your āextraā tools often.

Trolling Motor Batteries
Experienced boaters and fishing enthusiasts love their trolling motors. These awesome contraptions can get a boat from one point to another with incredible stealth. Quietly sneak up on bass and maneuver through shallow waters with ease, thanks to your trolling motor. They can also help you stay in one place without drifting or needing to lower your anchor. Most people charge their trolling motor batteries once the boat is docked or back home. Plug in your onboard battery charger and in a couple of hours theyāll be ready to hit the water again!
As you can see, an anglerās battery and charging needs can really vary. Thatās why many folks run batteries in series or parallel. When it comes to charging all of these batteries at once, our battery bank chargers and Ionic Multi Voltage Charger are a sure bet. Follow along as we discuss the benefits of both in the next section. And which option is the best marine battery charger!

How to Power More Than One Battery at the Same Time
If youāre looking for flexibility, weāve got it in spades. Imagine the hassle of having to lug one battery after another to an electrical outlet. Sure, lithium batteries are about half the weight of traditional lead-acid batteries, but it would still be exhausting and time consuming. Instead, choose an on-board charger with a cable cord. Better yet, choose a battery bank charger with these features! That way you can charge multiple batteries at once. And no lugging batteries around.
Our charger banks can even charge different types of batteries at the same time. So if your cranking battery is still an old lead-acid battery but youāve upgraded your trolling motor battery to lithiumā¦you can still charge them together! Letās discuss a few of your options:
