Boat House? Hop in for a Ride!

Before we reveal the potential of each battery under discussion, isn’t it good to understand the concept of boat houses?

Boat houses are also known as liveaboard or floating homes. These are real boats designed and modified for permanent or semi-permanent living. Wondering why people opt for such residences. Here er spit some interesting facts.

Such people often end up in boat houses for the sake of their love for the water. They find it as an opportunity to stay closer to water.

Some people have found them reasonable and cheap compared to traditional houses.

If you have an explorer inside you, the boat house may intrigue you too. People having an adventurous nature prefer to reside in such houses, move along, and explore new things.

People with a minimalistic approach also prefer boat houses. For many, it’s an attractive lifestyle that incorporates minimalism, and downsizing.

Now these declared residences must have basic requirements like power for lighting, heating and cooling, refrigerators, communication devices, and a lot more. Unlike typical residences, these houses, of course, aren’t connected to a grid. they rely on batteries to store and supply electricity for their daily basic needs.

This dependency thus makes the batteries an essential component of the boat houses. So, selecting the right battery is crucial for the smooth running of errands.

Navigate to the next heading to conclude which one is better. LiFePO4 vs AGM for boat house!

AGM Battery- What is it?

 AGM battery

AGM stands for Absorbent Glass Mat. This is a type of acid-lead battery designed to be maintenance-free while providing reliable power for a variety of applications.

It uses a glass mat separator to absorb and immobilize the electrolyte, which is a mixture of water and sulfuric acid.

The use of the glass mat separator is super technical. It eliminates the requirement for a free electrolyte and thus reduces the risk of leaks or spills. This Is how AG has attained the status of more reliable and durable batteries compared to other acid-lead batteries.

Moreover, these are resistant to shock and vibrations.  AGM batteries are sealed and thus require no maintenance. No addition of water or electrolyte is required during their whole lifetime. This makes them perfect for use in situations or setting where access to the battery is limited, such as boat houses.

Being capable of providing high power output and efficient handling of deep cycle applications. This is helpful in the regular charging and discharging of the battery without damaging itself.  The provision of high surge current makes these batteries a good storage and power supply option in applications that require high power for shorter periods, such as engine starting.

AGM batteries are sued in;

  • Automobiles
  • Boat houses
  • Motorcycles
  • Solar Power systems
  • Emergency Lightning
  • UPS systems
  • RVs

AGM and Its Use in Boat Houses

AGM is a popular choice for use in boat houses because it’s reliable and durable, and maintenance-free. Since bat houses are residential spaces, they require batteries to power various appliances.  Meanwhile, access to the battery in such houses is limited. So, AGM makes capable batteries to handle these electrical loads and provides power for extended time periods.

The most powerful reason for AGM’s use in boat houses is its extensive ability to withstand harsh marine environments. Since boat houses are constantly exposed to moisture, salt water, and vibrations, the chances of damage are high, and AGM doesn’t let it happen.

Moreover, these batteries are sealed, thus making them resistant to corrosion and moisture. Their built favors the provision of power for extended time periods.  

However, they have some disadvantages as well. These batteries are heavy, have a high initial cost, have a limited life cycle, may not be temperature resistant, and others.

Pros & Cons of Using AGM Batteries in Boat Houses




Maintenance free

Limited life cycle and may require a replacement sooner


Temperature sensitive


Heavy: These are heavy and may cause inconvenience, where battery weight may pose a problem for the appliance. 


High initial cost


Limited discharge rate

LiFePO4- What is it?

LiFePO4 battery

The king of batteries! LiFePO4 stands for Lithium Iron Phosphate. It is a type of rechargeable lithium-ion battery. It uses an iron phosphate cathode, a carbon anode, and a lithium-ion electrolyte.

The use of iron phosphate in the cathode makes it much more productive and advantageous than several other lithium-ion batteries. These advantages are safety, durability, and stability.  

High energy density is the hallmark of LiFePO4 battery. High density means these batteries can store a significant amount of energy in a relatively lightweight and compact body.

LiFePO4 batteries have a long lifespan. These have been found working for a sling for 10 years. Their quick charging and recharging make them ideal for high-power applications.

LiFePO4 batteries are reckoned for safety. Meanwhile, their high power and high density are known globally.

LiFePO4 batteries are used in;

  • Electric vehicles
  • Solar energy systems
  • Boat houses
  • Backup power
  • Electric bikes and scooters
  • Portable power
  • Industrial applications

Use of LiFePO4 Battery in Boat Houses

  1. LiFEPO4 batteries are incredible! We can safely say this because of the surge in their popularity in boat houses.
  2. Powering Electrical Systems: these are the best options to power electrical appliances in boat houses. You can use them to power lights, refrigerators, communication systems, etc. It is their high energy density and fast charging capabilities that make them fit for powering systems.
