Why Use A Battery Box?

Safety

One of the most important reasons for using a battery box is that it helps to protect you from electrocution and any harmful toxins that might be released from the battery. These gases can be emitted even from sealed batteries while charging, so it can be a good idea to have a battery box to help provide an extra layer of protection.

Another reason is that the battery box can help to protect your battery by keeping it safe and dry, sheltered from any splashes that might come aboard your kayak or boat. This can help to prolong the life of your battery, protecting it against corrosion.

It can also help to stop your battery coming into contact with other conductors, such as any metals that might get close to your battery. This can help to minimize the risk of short circuits and shocks.

Additionally, a battery box can be useful if you use a lead acid battery, as it can help to protect the battery from spillages and help to prevent it from leaking battery acid over your equipment.

Convenience

Battery boxes can make it easier for you to connect your trolling motor because in many cases, you shouldn’t need to touch the battery, as the battery is wired to the battery box. This means you can connect your trolling motor directly to the box.

However, some battery boxes may have ports in the lid rather than terminals. These let you thread your wires through the holes or ports to connect your trolling motor to the battery.

Many battery boxes are also designed so that you can charge your battery while it’s inside the battery, which can, again, make it more convenient for you.

Waterproof

Marine battery boxes are designed to be waterproof, but they aren't water tight. They can take some splashes, which is what you'd expect.

It goes without saying: you don't want to submerge the box in water!

Should I Get A “Smart” Box?

A smart battery box can be a good idea if you want to be able to charge your phone or other electronics at the same time. Smart boxes can offer additional power ports, such as USB ports, letting you power additional gadgets from your battery.

Smart boxes can also give you a better idea of the charge level of your battery, effectively letting you know if it will soon require recharging. They will also usually have a built-in circuit breaker which can give an added layer of protection.

These types of battery boxes can be useful if you prefer to have a more convenient set-up, as you can often recharge the battery while leaving it inside the box, with the battery indicator on the outside letting you know when it’s fully charged.

If you only need your battery box to protect your battery while you’re on the water, you may not need a smart box and a standard box could be sufficient.

What Features Should I Look Out For?

Vents

Vents can be important on a battery box to allow any gases released from the battery to escape. Ventilation can help to prevent the build-up of some of the gases within the box that could be dangerous and potentially cause an explosion.

Power Outlets

Having another power outlet on your battery box can let you charge other items from your battery, such as a phone or other electronics. Some battery boxes may have multiple outlets, including USB ports, so that you can charge a range of items more easily. 

Battery Charge Indicator

A battery charge indicator can be a useful feature to have on a battery box, as this can let you see how much charge you have left in your battery, giving you a better idea of when you need to head back to shore to recharge.

Non-Slip Feet

Non-slip feet or a non-slip bottom can be useful for battery boxes that will be on a kayak or small boat, as they may frequently be on wet or slippery surfaces. The non-slip feet can help to provide traction for the battery box so that it can maintain its position on your deck without sliding around.

Strap

An important safety feature that you might want to look out for is a strap. Most battery boxes will usually come with a strap included. This helps to keep the box secure, keeping your battery safe inside. A buckle closure can be handy for opening and closing.

Circuit Breaker

This can be an important feature to look for on a battery box, as a circuit breaker can help to cut the power in the event of an overload, helping to protect your connected electronics.

How To Hook Up A Marine Battery Box

Step 1: Place Your Battery Inside The Battery Box

The first thing to do is to put your battery into the battery box so that the terminals are on the top.

Step 2: Connect Your Wires

Connect the wires from the battery box to the terminals on your battery, with the positive (red) wire being connected to the positive terminal and the negative (black) wire to the negative terminal.

> Wiring your motor

Step 3: Secure The Lid

Close the lid on your battery box and use the strap to secure the lid.

Step 4: Hook Up Your Trolling Motor

Now that your battery box is securely closed, you can connect the cables from your trolling motor to the terminals on your battery box. Again, red cable to the positive terminal and black cable to the negative terminal.

If your battery box does not have external terminals you should connect the trolling motor cables directly to the terminals on the battery, either through the slots provided or with the lid removed.


Last Words

We think the best battery box for your trolling motor is the Newport Vessels Smart Battery Box because it has external terminals with additional power ports for extra gadgets, plus it’s compact for kayak use and has dual circuit breakers.

However, a good runner-up is the MinnKota Trolling Motor Power Center, as it can be a good choice for kayaks and small boats. It has the benefit of having two 12 volt accessory plugs, as well as circuit breakers and a battery level indicator.

When you’re choosing your own battery box remember to check the dimensions of the box to make sure it will fit in your boat and to make sure your battery will fit. It can also be beneficial to think about some of the additional features you might want and whether or not you need a more advanced battery box or a more simple one.
