Why the SEAL™ 36V Battery Features Integrated Fire Suppression — And Why It Matters

Safety Isn't an Option. It's Engineered In.

As lithium battery technology continues to evolve, safety has become one of the most discussed topics in the marine industry. Boat owners, OEM manufacturers, dealers, and installers are all asking the same question:

"What happens if a lithium battery experiences a thermal event?"

At ABYSS Battery®, we believe the best answer isn't a reaction plan—it's prevention.

That's why we developed the SEAL™ 36V 105Ah Lithium Trolling Motor Battery, the first battery in its class to feature an integrated aerosol fire suppression system engineered directly into the battery's design.

This isn't a marketing feature. It's a deliberate engineering decision made to provide an additional layer of protection for serious anglers, boat builders, and marine professionals who demand the highest level of safety and performance on the water.

Why We Added Internal Fire Suppression

Innovation isn't about following the market. It's about anticipating where the market is going.

As lithium batteries become larger, more powerful, and increasingly integrated into modern fishing and boating platforms, we recognized an opportunity to raise the standard for battery safety.

The result was the SEAL™ platform.

The internal fire suppression system is designed to automatically deploy in the unlikely event of a severe thermal incident within the battery enclosure, helping to suppress and contain the event before it can escalate.

While ABYSS batteries are built using premium LiFePO4 chemistry—already recognized as one of the safest lithium chemistries available—we believe additional protection is never a bad thing when it comes to protecting your boat, investment, and time on the water.

Does the Fire Suppression System Require Inspection or Maintenance?

One of the most common questions we receive is:

"Do I need to inspect or service the fire suppression system like a traditional fire extinguisher?"

The answer is no.

The aerosol fire suppression technology utilized within the SEAL™ battery is designed as a maintenance-free, sealed system.

Unlike conventional portable fire extinguishers, which require periodic inspections, servicing, and recertification, the suppression device inside the SEAL™ is engineered to operate throughout its service life without routine maintenance.

The system is sealed from the factory and is not intended to be opened, recharged, or serviced.

This maintenance-free design is one of the key advantages of modern condensed aerosol fire suppression technology.

Understanding Fire Extinguisher Inspection Requirements

Many customers reference annual fire extinguisher inspections, and rightfully so.

Under NFPA 10 (National Fire Protection Association) and various OSHA requirements, traditional portable fire extinguishers installed in workplaces, commercial facilities, and public environments generally require:

• Monthly visual inspections
• Annual professional servicing and certification
• Hydrostatic testing every 5–12 years depending on extinguisher type

These requirements exist because traditional extinguishers can lose pressure, become damaged, or experience degradation over time.

However, aerosol-based suppression systems operate differently.

Certain condensed aerosol fire suppression devices certified for long-term deployment are designed as sealed, non-rechargeable systems that remain in service throughout their certified lifespan without routine maintenance requirements.

In these applications, readiness is established through product design, certification testing, and validated service life rather than periodic manual inspections.

The Trigger Mechanism:

When temperature sensing wire sense temperature over 356
Fahrenheit (185 Celsius) or above, the fire suppression will go off. 

There are three ways to trigger it:
1. Overcharging the battery , which is hard to control exactly;
2. Nail penetration, which will cause instant explosion, which is extremely dangerous;
3. Heating, by adding high power heating film around the battery pack, and heat it to
desired temperature, the thermal runaway got triggered, there will be over 400
Fahrenheit (200 Celsius) gas coming out, just as seen in the video.

What Is the Expected Service Life?

The integrated fire suppression system inside the SEAL™ battery has a conservative service life rating of 10 years.

In reality, the suppression technology has undergone aging evaluations extending beyond that period, but ABYSS utilizes the 10-year specification as a conservative and responsible benchmark.

This aligns with the service expectations of many premium marine lithium battery installations and provides long-term confidence for boat owners and OEM partners alike.

How Do We Know It Will Work Years From Now?

The suppression technology used in the SEAL™ platform is supplied by one of the industry's leading manufacturers and has undergone extensive environmental and durability testing.

Testing includes validation against:

• Vibration
• Mechanical shock
• Pressure resistance
• Salt spray exposure
• High-humidity environments
• Elevated temperature conditions
• Long-term aging simulations

The technology is also designed to comply with recognized industry safety standards, including UL 2775 requirements for aerosol fire suppression systems.

These tests are particularly important in marine applications, where equipment must survive harsh offshore conditions, continuous vibration, saltwater exposure, and extreme temperature swings.

Simply put, this technology was selected because it can withstand the environments where ABYSS products are expected to perform.

Does the Battery Monitor the Fire Suppression System?

Another common question is whether the battery provides a warning if the suppression system becomes compromised.

Current condensed aerosol fire suppression systems are designed as self-contained devices and do not require active monitoring to remain operational.

While advanced battery management systems (BMS) could theoretically be designed to monitor suppression device status, this is not currently standard practice within the condensed aerosol fire suppression industry.

The suppression unit utilized in the SEAL™ battery is designed as a passive, maintenance-free safety system intended to remain operational throughout its service life without user intervention.

Why This Matters for OEM Boat Builders

For OEM boat manufacturers and marine installers, safety, reliability, and simplicity are critical.

The SEAL™ platform was engineered to provide all three.

By integrating fire suppression directly into the battery design, OEM partners gain:

Enhanced Safety

An additional layer of protection beyond traditional battery management systems.

Reduced Maintenance Requirements

No annual inspections, servicing, or recertification requirements for the suppression device.

Simplified Installation

The system is integrated directly into the battery platform without requiring external suppression equipment.

Long-Term Reliability

A 10-year service life backed by extensive environmental and aging validation.

Premium Product Differentiation

A feature set that helps boat builders offer customers one of the most advanced lithium battery platforms available today.

The ABYSS Philosophy

At ABYSS Battery®, we don't believe innovation should happen only when regulations require it.

We believe innovation happens when companies identify opportunities to build something better before the market demands it.

The SEAL™ 36V 105Ah battery was developed with that mindset.

Premium LiFePO4 cells.

Advanced Battery Management System technology.

Marine-grade construction.

And an integrated fire suppression system engineered specifically to provide an additional layer of confidence on the water.

Because when you're running offshore, competing in a tournament, or building the next generation of premium boats, confidence matters.

The SEAL™ wasn't designed to meet expectations.

It was designed to redefine them.
