Several factors will come into play when trying to work out how long a battery will take to charge. These are; how much power the battery has  36V lifepo4 battery remaining, they type of battery, the age of the battery, the condition of discharge, and the type of charger used. A 100 amp battery being used by a motor that pulls 25 amps at a medium speed would last 4 hours. The motor amperage draw refers to how much power a motor consumes at any given speed. Finding out the motor amperage draw can be difficult at the best of times, although the manufacturer instructions or website should tell you this. Unless you enjoy being slowed down by tides, friction and adverse weather conditions, the last thing you want is to have too little thrust.

The Power Series AGM is their top-of-the-line Group 27 deep cycle battery. With improved efficiency and storage, this battery is rated to fish all day and take a beating. The AGM has a higher cold cranking rating and longer reserve time than lower-priced models. Lithium batteries weigh 60% less than equivalent lead-acid models—a 100Ah lithium battery averages 26 lbs vs. 65 lbs for AGM. Reduced weight improves boat stability, fuel efficiency, and payload capacity.

Instead, look for voltage regulation chargers, as these offer full and fast charges. Thankfully, most anglers won’t have too much weight on their boat so a heavier battery may not be a problem. In most cases, batteries weigh between 20 and 50 lbs, with anything below 30lb recommended for anyone using a kayak.

Prioritize batteries with built-in Battery Management Systems (BMS) for safety and marine certifications like IP67 for water resistance. The AGM is placed between the specially formulated plates inside the battery and absorbs the electrolytes creating a safe and spill free battery. This battery is designed to provide up to 4 hours power for a 40 lb motor and up to 9 hours power for an 18 lb motor. It is built with heavy duty lead tin alloys to ensure high performance and extended service life, even after repeated discharges.

So the mat not only protects the battery from leaking, but it also extends the lifespan of the battery. With that said, here are some of the best trolling motor batteries you can buy. Their service is some of the fastest and preventative in the industry. Their app checks for potential problems on a constant basis with the battery. The app will report a slight degradation in any cell, so you can file a claim and get a replacement quickly BEFORE YOUR BATTERY DIES.

How We Picked The Best Trolling Motor Batteries

The manufacturing and design will be similar to that of the Solar Wind above. ExpertPower also does a good job of providing customer satisfaction with positive reviews, while keeping the price down. This is a much lighter battery as well, and being so only stores 33 amp hours of thrust power.

What many folks don’t know is that 36V controllers are made to work in 36V environments and give you way more leeway in one battery degrading your whole system. First, you have to understand in parallel or series systems, when one battery goes down, the whole thing is down. If, on the other hand, you want a light and high-performing battery that will last you many years, lithium is the way to go. I recommend you also read reviews and learn about other users’ experiences with customer support. It’s great if you know you can pick up your phone and get any advice you may need. In this case, your motor shouldn’t draw more than 60 Amps, preferably closer to 50 Amps.

What Kind Of Battery Should I Use For A Trolling Motor?

The batteries need to provide ample energy and duration to power your various needs on the boat or kayak and, the batteries need to do so for many years. Car batteries cannot be recharged and be brought down on water levels over and over again. If you use car batteries, you may end up buying and installing three or four of them before a quality trolling motor batteries wears out.

Trolling motors use deep cycle batteries, and the car battery (usually the cranking type of battery) isn’t ideal for a trolling motor. For example, if you have a 100 amp hour trolling motor battery, and the motor pulls 40 amps at top speed. The trolling motor battery life should be around 2.5 hours (100 Ah / 40 amps) at top speed.

For 24V/36V systems, connect multiple 12V batteries in series using marine-grade wiring. Each trolling motor will be fitted with a 12v AGM deep cycle battery, with low hours of power supply over a long time. CCA rated batteries are cheaper than deep cycle units and they will power your trolling motor but not for long. They are designed to provide large amounts of power over a short period (to start an engine).

Trolling motors with 80 pounds of thrust are most often found on larger boats such as bass boats, pontoons, and small center console fishing boats. They are powered by two 12 volt batteries wired in series for 24 volts in total. I ran a trolling motor the other day on a windy day for about 4 hours. When I got off the water and checked the charge (part of my testing), I had used hardly anything for power. I hooked it up to my 36V 18A Dakota Lithium Charger, and in 8 minutes my batteries were fully charged.
