Let's also not forget that it has a compact and lightweight design.

The catch?

Regardless of its lightweight design, hanging it might be a struggle for you because of the hanging mechanism.

Aside from that, it is a great choice for you if you are looking to get a mid-range solar-powered trolling motor battery charger.


  • Lightweight and compact design.
  • Can withstand water splash but do not toss it into water.

All solar-powered chargers gain their superpowers from the sun. As a result, they probably would only be able to function well while they are underneath the sun.

However, some solar-powered chargers can function properly in any weather. For example, this solar panel from SOLPERK is quite fluid when it boils down to business.

Thanks to its thin-film nature, it will charge your battery even during cloudy days. You know, those days you really want to go fishing, but the sun seems to be missing in action? Yes! This solar panel would come through for you.

Like the other solar chargers, it does the work of charging and maintaining your battery life.

Fun fact: it is wind and rainproof. So, if you enjoy fishing in the rain, you can take this solar panel with you.

However, there's a but clause to the rainproof feature.

You should have noticed by now that the manufacturers said it is "rainproof" and not "waterproof."

In other words, while it can stand rain without getting damaged, you should never dip or immerse it in water. That would damage the panel entirely.

But there's a piece of good news: it comes with a one year extended warranty. Also, technical support runs for a lifetime.

I should also state that like all solar chargers, this charger charges slowly. So don't expect a flash charge. You still would need a lot of patience for it to charge your trolling motor battery.

But, you can boost the charging effect by exposing it to more than enough sunlight.


  • Rust and corrosion-resistant.
  • Thick wires.
  • Weatherproof. That is, it works perfectly in any weather.
  • Compatible with a 12 Volts battery.

5. DuraVolt Trolling Motor 24V battery charger

Being a weatherproof panel, no weather condition can stop it from functioning well.

The best part is that it is lightweight. Easy to carry and easy to install. You almost won't feel any weight as it is almost as light as a feather.

The best part is that, unlike other panels, you don't have to worry about the panel heating up while charging your battery.

If you are prone to forgetting things such as leaving your battery charging without checking to see if it's fully charged, here's good news for you.

You can now leave your battery to charge for as long as it can. Once it is full, this solar panel would regulate itself by disconnecting itself once your battery is fully charged.

However, it charges slow. So, maybe leaving it to charge and even forgetting that you're charging your trolling motor battery is a blessing in disguise.

Also, you can leave it plugged In while you use your trolling motor. It wouldn't damage anything.

How To Choose Solar Charger for Trolling Motor Battery

Eco-friendly anglers entirely subscribe to the idea of powering your trolling motor battery with Solar powered chargers rather than the regular AC models.

Their reason is pretty obvious. The environment is changing. More precisely, degrading.

And the best way to save the planet is to use eco-friendly options. For example, Solar-powered Trolling Motor battery chargers are an eco-friendly option that other anglers can use.

However, with countless Solar Powered Trolling Motor Battery chargers on the market, it could be tough to tell which one is the best and would fulfill your need.

But, never mind. We show you how to choose the best solar charger for trolling motor batteries in this section. Keep reading

1. Power

Of course, power is an important factor. I mean, we're talking about chargers, right? So yeah, you should check the power of the solar panel.

And the reason is this: you don't want to buy a charger that wouldn't charge your trolling motor battery at all. Or a charger that would charge it slowly. Trust me, that is excruciating.

But, now this begs the question: how much power should a solar charger have? While the question seems like a piece of cake, there is no single streamlined response.

However, when hunting for a solar-powered charger, ensure that the wattage starts from 100.

A solar charger with a 100watts panel is strong enough to charge your trolling motor battery.

2. Charge Controller

We all want things that would last for a very long time.

Getting a charge controller would preserve the life of your battery, making it last longer.

But, you'll put the life of your trolling motor battery at risk if you connect the solar panel directly to your battery.

Basically, the charge controller will be the conduit that conveys electric power from the panel to your trolling motor battery.

3. Type of Solar Charger

A crucial point to bear in mind when charger hunting is that there are three types of solar chargers, and they have different capacities.

First is the Polycrystalline panels. This charger type is defined by its efficiency, corrosion resistance, the large amount of energy it can produce, and, of course, its ability to last long.

As its name suggests, it is made with the use of multiple silicon crystals. These multiple silicon crystals are possibly responsible for their stereotypical blue color.

The second type of solar charger is the monocrystalline charger. Yes, you guessed right. It is carved from one crystal. Hence, black in color.

Interestingly, however, the monocrystalline chargers have higher capacity and work better than the polycrystalline chargers.

Here's what I mean. While the polycrystalline chargers are efficient, monocrystalline chargers are found to be more efficient than its counterpart.

It also works well in situations with low light. And, when it comes to the energy it produces, it is undoubtedly more than a polycrystalline charger produces.

But there is a catch! Monocrystalline chargers are way more expensive than polycrystalline chargers. Surprised? Well, don't be.

Logically, since monocrystalline chargers seem to outperform polycrystalline chargers in certain key aspects, it is only normal for it to be more expensive. But, you sure would get value for money.

The thin film makes the third type of charger. When it comes to efficiency, the in-built semi-conductor gives it a boost.

Although this increased efficiency makes this narrowly designed charger seem promising, the fact that its absorbing layers are light greatly limits its performance.

4. Size

This feature ensures that your battery is compatible with the charger. In clearer terms, for your battery to successfully charge, ensure that the charger's voltage equals your battery's voltage. It would promote your charger's efficiency.

5. Overcharge Protection

Okay so, it's an established fact that Solar chargers are quite slow when it comes to charging batteries.

But, they still deliver a great charge performance. Hence, as a Human being, you might tend to leave your battery charging for long without attending to it.

As a result, you might not know when the battery is fully charged. Here is where the overcharge protection steps in to save your battery's life.

A solar-powered charger with overcharge protection ensures that your battery doesn't overcharge.

So, once your battery is full and you're not there to unplug, it automatically disconnects itself from the battery to prevent the battery from overcharging.

It does this until you can finally manually unplug the charger from the battery. Awesome right?

6. Battery Conditioning

When Charger hunting, you should bear in mind the lifecycle of your battery.

In other words, ensure that the charger you're looking for won't damage your battery.

A great solar power charger that can help you prolong the lifespan of your battery is one that can de-sulfate it.

Note: these types of solar-powered chargers are definitely expensive.

But, trust me when I say that you would be happier with the charger.

7. Warranty

You would be giving yourself a treat as an angler if the solar charger you buy has a really long warranty period.

Ensure that the brand you purchase has at least one to two years warranty and, at most, a lifetime warranty (if that's possible).

How Can I Use Solar Power for My Trolling Motor?

You can charge your trolling motor battery using a solar-powered charger.

Although charging your trolling motor battery with a solar-powered charger is one of the three ways to charge your battery, using a solar charger is easy and less dramatic.

What do you need? For starters, you need a solar panel. The other equipment you need includes a boost converter, relay circuit (if you're going to charge more than one battery), sun rays, and a truckload of patience.

Start by placing the solar panel in a way that sun rays can get to it. On days when sun rays are barely enough, the boost converter would prove useful.

What it does is to absorb the little or dim ray of light that it can get and effectively utilize it.

If you are going to charge more than one battery, a relay circuit would be useful. Once it starts charging your battery, you would need a lot of patience.

Reason? Solar charging is slow, but it is effective.

Solar Charger Frequently Asked Questions (FAQs)

1. How long does it take to charge a trolling motor battery?

There is no generic and specific time frame for a trolling motor battery to charge. The reason is simple. A lot of factors affect the charge time of a trolling motor battery.

For example, the battery's reserve capacity, the output of the charger, how low the battery has gotten, the type of charger you're using, etc. If these factors, and more, are in good shape, then your battery shouldn't take too long to charge.

2. How long will a trolling motor battery last per charge?

While this question is a good and thoughtful one, it has no single answer. Why? Different factors affect how long your trolling motor battery will last on the sea. Factors like the quality of your battery (are you using a deep cell battery? What type of deep cell battery are you using?), the age ( how long have you been using it? How long is it supposed to last?)

The battery percentage before taking it out on another fishing spree, and the battery's capacity. Once you have the answers to these factors, you should be able to know how long your trolling motor battery will last.

3. Can an overcharge damage my trolling Motor Battery?

Not really. It depends on the type of charger you charge it with. Using a solar-powered charger with a battery conditioning feature would definitely not damage your Trolling Motor Battery.

Since solar chargers take time to fully charge your trolling motor battery, you might not know when it gets fully charged. Rather than overcharge the battery, the battery conditioning disconnects itself once the battery is fully charged. So, your battery is safe.
