The Definitive Guide to electric outboard motor battery

electric outboard motor Overview

Outboard refers to the propulsion engine installed on the outside of the hull (side of the boat), is a kind of removable power unit hanging on the transom plate of the boat, boat, boat sailing, also known as outboard, boat engine, hanging engine.

Mainly by the engine and transmission, operation, suspension devices propellers, and other components. The start-up mode is mostly manual, and the direction is mastered by the operator holding the direction handle.
Outboards are highly integrated, have a compact structure, are lightweight, easy to disassemble, easy to operate, low noise, etc., and are suitable for use in inland rivers, lakes, and offshore.

The application of outboards in the global civil field is mainly reflected in the three aspects of water recreation, coastal fishing and owning boat. It is the preferred power for personal recreational dinghies and is also widely used in commercial operations and government law enforcement.

. Militarily, they are commonly used in boats, launches, and door bridges that perform tasks such as reconnaissance, logging, river crossing, patrolling, and life-saving.

Stringer batteries can be categorized by their power into many models ranging from 6 hp, 8 hp, 15 hp, and 30 hp;
According to the source of power, it is divided into fuel-based string outboards and electric string outboards;
In terms of fuel technology, generally two/four-stroke gasoline engines. Two-stroke marine power favors affordable price, strong power, and simple structure; four-stroke environmental protection and noise is more superior to two-stroke, low fuel consumption, performance is also more durable and reliable.

Electric outboards have gradually become the dominant market, able to safely and efficiently output the power needed for outboards.

Development history of Outboard Motory

The outboard first appeared in the late 19th century. since the 1960s, some countries to reduce the weight of the maneuvering boat, the use of high-strength aluminum alloy and alloy steel and rubber, plastic and other materials, in order to improve the performance of the engine, the use of reflux sweeping, intake and exhaust tuning, high-energy non-contact fire and other measures. In the promotion mode, the United States, the Soviet Union and other countries also develop water jet propulsion to adapt to the boat, boat navigation in shallow water.

e Marine Outboard

Wholesale prices are dropping as motor and battery production increases, especially in the automotive industry. Electric outboards are intuitive to use and require little maintenance, and customers are beginning to appreciate the quiet, smoke-free comfort of the experience.

Blockades and home vacations over the past two years have prompted people to look for convenient ways to get on the water locally, and growing concern for the environment has prompted many to turn to electric propulsion technology, albeit at a higher initial cost.

A lightweight outboard suspended over the side of a boat, or a small pod thruster or drive that can be quickly attached to the stern or rudder, can help a paddleboarder, dinghy sailor, or kayaker achieve greater sailing distances.

When a kayaker is too tired to paddle, he or she can get back to shore safely if the energy inside this small waterproof battery pack is utilized wisely. Thanks to their discreet design, reliable performance, and near-zero recharging costs (average of €0.21/kWh in Europe and $0.13/kWh in the U.S.), users will be “thinking about these electric options” when planning family outings.

Designers are enthusiastically applying hydrofoil technology to a wide range of boats such as surfboards, water bikes, catamarans, motorboats, and sports boats, all of which can now float on water at high speeds.

This has led to several exciting new yacht designs on the market. Electric string outboards are not only a new form of water recreation but also reduce pollution of the water and the planet.

Diesel Outboard Motory

If the outboard industry has been active lately, none more so than the diesel outboard segment. Although developed primarily for the commercial market, diesel outboards continue to attract interest from the leisure yacht sector. Luxury yacht owners appreciate the fuel versatility of this type of outboard, making them happy to power their dinghies with it. 

At the same time, those buying large rigid inflatables and center console yachts looking for a propulsion system also appreciate the fuel economy and longer range of diesel outboards.

Diesel outboards are ideal for boats that need to travel long distances into the ocean, but diesel stringers produce exhaust fumes or diesel spills that pollute the environment. Instead of diesel as a power source, electricity is an environmentally friendly and clean source of energy.

Portable Outboards Motor

With the progress of the times, portable string outboards can use both internal combustion and electric, portable string outboards in small kayaks using a lithium-ion battery pack is a safe and convenient new energy source, able to provide higher energy efficiency in a small space, small volume.

How do you pick a string outboard battery that's right for you?

Determine the voltage and power of the string outboard battery

You need to check your outboard’s specification label or owner’s manual for the required voltage and power. A typical electric outboard may require a 12V lithium battery, 24V lithium battery or a higher voltage battery.

For example, a 12V outboard may need at least 100Ah battery to ensure sufficient usage time, but you also need to consider whether the battery can match the chord outboard battery chassis, a larger battery may not fit inside the chord outboard.

Selecting the right battery for the length of use

The capacity of a battery is usually measured in ampere-hours (Ah). A higher Ah value means a longer usage time. For example, a 12V 20Ah is capable of sailing for about 2 hours at 40% power output, if you need longer sailing time. Then a higher capacity battery pack is required. Commercial fishing boats may opt for a 200Ah+ battery for all-day operation.

Choose a battery pack or battery for specific scenarios

When you need to use a string outboard in fresh water, then a waterproof lithium battery is your priority, as it better protects the battery from water ingress, which can cause the string outboard to lose its operation. For use in salt water, you need to choose not only waterproof but also corrosion-resistant batteries so that the batteries can be better protected and have a longer service life. Lithium batteries are usually more resistant to corrosion, have a longer cycle life and a higher energy density.

Are you sure you want to use Lithium Ion or Lead Acid or Nickel Metal Hydride batteries?

144V 100Ah Electric Outboard Motor battery

Lithium-ion batteries: Lightweight, small, fast charging, but more expensive for frequent use and weight-sensitive applications.

Lead-acid batteries: cheaper, but heavier and require more maintenance, suitable for limited budgets and infrequent use.

Nickel-metal hydride batteries: are environmentally friendly, but energy density and cold-temperature performance are not as good as lithium batteries.

Which string machines are lithium batteries compatible with?

Generally speaking, Li-ion batteries are compatible with Yamaha/ Mercury Marine/ Honda Marine/ Suzuki Marine/ Evinrude/ Tohatsu/ Torqeedo/ Johnson outboards to ensure that they can be used properly, but you need to pay attention to ensure that the battery and the power of the outboard correspond to each other. 

However, you need to be aware of the need to ensure that the power of the battery corresponds to the power of the outboard, you can consult the supplier of the outboard or the manufacturer of the lithium batteries to use compatible batteries to ensure optimal performance and avoid damage to the equipment.

How to charge an electric outboard engine?

Choose the correct charger for your battery type. For example, lithium batteries require a specialized lithium battery charger.

Charge regularly to maintain proper battery charge even when not in use for long periods to avoid degradation of battery performance.

Avoid charging in extreme temperatures, especially high or low temperatures.

Charge exactly according to the manufacturer’s instructions, including charge time and current settings.

Who are the manufacturers of string outboard Motory batteries?

Optima, Trojan, and Interstate are well-known brands in the lead-acid battery market that offer various models of batteries for outboards. Panasonic, Samsung SDI, and LG Chem are globally recognized lithium battery manufacturers that offer high-performance battery solutions.
These globally recognized branded batteries usually come at a serious premium, so are there any cost-effective suppliers?
