Electric propulsion offers many advantages, including lower emissions, quieter performance and simpler maintenance than internal combustion engines. Lithium batteries, in particular, have optimized this transition to more efficient, environmentally-friendly electric propulsion.
Two types of battery for your electric motor
Equipping your fishing boat with an electric motor offers many advantages, but to get the most out of it, you need to choose the right battery system. There are two battery systems on the market: the slow-discharge lead marine battery and the lithium battery case. Both options have their advantages and disadvantages.
Slow-discharge lead-acid batteries
Slow-discharge lead-acid batteries offer the advantage of good autonomy for propelling your fishing boat with your electric motor. But their weight is really important: for example, a 12-volt 125 Ah slow-discharge battery weighs 28 kg. However, it is perfectly suited to most electric boat motors, and will enable you to enjoy long fishing sessions.
To propel small 2 m to 3 m boats with a standard electric motor (e.g. a Eco Booster V 36 Lbs you can use a 80 Ah 12 V slow-discharge battery which weighs 18.7 kg. It's perfectly tuned to give the motor the energy it needs to propel your boat.
For 12-volt electric motors with a power rating of 55 lbs or more (such as the Eco Booster V 70 Lbs 12 V or front-mounted electric motors such as the Minn Kota Powerdrive or Terrova 55 Lbs slow-discharge battery pack in 125 Ah with matching charger is excellent value for money.
Lithium battery cases
The power supply for electric motors used to propel boats has undergone a significant revolution with the advent of lithium batteries. These batteries, renowned for their high energy density and superior storage capacity compared with previous technologies, have opened up new horizons in boating and fishing.
Thanks to their ability to store large amounts of energy in a small space, lithium batteries are ideally suited to marine applications where space and weight are critical considerations. Their modular design also enables flexible installation, adapting to a variety of configurations to power boats and pleasure craft, both large and small.
For anglers who want a lighter, more practical option, we strongly recommend one of our lithium battery cases (from the brand Prolith or even BSR two of the market's leading brands). Suitcases whose weight and compactness are perfect for all fishing boats or even pleasure craft.
Lithium batteries offer a unique combination of high performance, extended autonomy, light weight and robustness, making them an ideal choice for powering electric motors on boats and barges, while contributing to safer, more environmentally-friendly navigation. Compared with slow-discharge lead batteries, lithium batteries offer much higher energy density. For example, a 40Ah lithium battery can be equivalent to an 80Ah lead battery, while weighing just 5kg. This optimizes on-board space and reduces the boat's overall weight, resulting in greater energy efficiency and greater range.
For greater comfort on board your fishing boat, these marine batteries are maintenance-free and resistant to shock and vibration. They can withstand very high charging and discharging speeds. Choosing a lithium battery case involves a non-negligible extra cost compared with a slow-discharge lead-acid battery, but it remains a very worthwhile investment for optimum fishing comfort.
