What Is the Abyss 36v Lithium Battery INFINITE Series?

The Abyss 36v Lithium Battery INFINITE Series uses lithium iron phosphate technology. It replaces heavy lead-acid batteries with a lightweight, efficient power source. This battery powers trolling motors, RV systems, and marine electronics.

Core Technology Explained

This battery uses LiFePO4 cells – the safest lithium type. These cells don’t catch fire easily. They last thousands of charge cycles. The built-in Battery Management System protects every cell automatically.

Key technology features:

  • Advanced cell balancing
  • Temperature monitoring sensors
  • Automatic protection systems
  • Waterproof sealed casing
  • Efficient power delivery

Complete Specifications

Feature Specification Real-World Benefit
Voltage 36 volts Powers all 36V systems
Cycle Life 5,000+ cycles Lasts 10-15 years
Weight 30-45 lbs 70% lighter than lead-acid
Charge Time 3-4 hours Fast turnaround
Efficiency 98% Almost no waste
Operating Temp -4°F to 140°F Works in extreme weather
Discharge Rate 100A continuous Handles high power needs

How It Compares to Lead-Acid

The difference is dramatic:

Feature Abyss Lithium Lead-Acid
Weight 35 lbs 110 lbs
Lifespan 10+ years 2-3 years
Usable Capacity 100% 50%
Charge Time 3-4 hours 10-12 hours
Maintenance Zero Regular
Efficiency 98% 80%

You get double the usable power because lithium can discharge to 100%. Lead-acid only gives 50% safely.

Why Choose the Abyss 36v Lithium Battery INFINITE Series?

The benefits are substantial and immediate. Let’s examine each advantage.

Dramatic Weight Reduction

The Abyss battery weighs 65-70% less than lead-acid. A 100Ah lithium battery weighs 35-40 pounds. The same capacity in lead-acid weighs 110-120 pounds.

Real-world impact:

  • Boats ride higher in the water
  • Faster acceleration and top speed
  • Better fuel economy (3-5% improvement)
  • Easier handling and installation
  • Improved boat balance and handling

“The weight savings transformed my boat’s performance. I gained 3 mph top speed and better handling. Game changer for tournament fishing.”

— Mike Stevens, Tournament Angler

Extended Runtime Performance

You get 30-50% more runtime compared to lead-acid. That translates to 8-12 hours of continuous trolling motor use.

Battery Type Rated Capacity Usable Capacity Actual Runtime
Lithium 100Ah 100Ah 100Ah 10-12 hours
Lead-Acid 100Ah 100Ah 50Ah 5-6 hours

10-Year Cost Comparison

Superior Cost Efficiency

Yes, the upfront cost is higher. But the total ownership cost is lower. Here’s the complete analysis:

Cost Category Lithium Lead-Acid Difference
Initial Purchase $1,500 $400 -$1,100
Replacements $0 $2,800 (7x) +$2,800
Charger $200 $50 -$150
Maintenance $0 $300 +$300
Electricity $120 $200 +$80
Disposal Fees $0 $70 +$70
10-Year Total $1,820 $3,820 +$2,000

Break-even occurs at year 3-4. Total 10-year savings: $2,000

Technical Features Breakdown

  • 🚨 Unusual odors
  • 🚨 Excessive heat during use
  • 🚨 Leaking fluids
  • 🚨 Smoke or burning smell
  • 🚨 Sparking at terminals

Fire Safety

While LiFePO4 is the safest lithium chemistry, follow basic fire safety:

Prevention:

  • Charge in open, ventilated areas
  • Never charge unattended overnight (first few times)
  • Keep a fire extinguisher nearby
  • Don’t charge near flammable materials
  • Inspect cables regularly for damage

In case of fire:

  1. Evacuate immediately
  2. Call emergency services
  3. Use a Class D fire extinguisher if safe
  4. Do NOT use water on lithium fires
  5. Let professionals handle it

Environmental Impact and Recycling

Advanced Tips for Power Users

Maximizing Battery Lifespan

Pro tips from experienced users:

  1. Avoid 100% charges when possible – Charging to 80-90% extends lifespan. Only charge to 100% before long trips.
  2. Don’t discharge below 20% – While safe to go lower, keeping above 20% maximizes cycle life.
  3. Store at 50-60% charge – This is the ideal storage charge level for long-term health.
  4. Avoid temperature extremes – Keep battery between 50-80°F when possible for optimal longevity.
  5. Use slow charging when time permits – Lower amp charging (20-30A vs 50A) reduces stress on cells.

Performance Optimization

Getting the most from your battery:

  • Cable quality matters – Upgrade to 4 AWG or larger cables for maximum power delivery
  • Keep connections tight – Loose connections waste power and generate heat
  • Monitor voltage – Install a battery monitor to track real-time performance
  • Balance speed vs runtime – Running trolling motor at 70% vs 100% dramatically extends runtime
  • Reduce parasitic drains – Turn off electronics when not in use

Winter Storage Best Practices

If you won’t use your battery for months:

  1. Clean thoroughly – Remove dirt, salt, corrosion
  2. Charge to 50-60% – Not full, not empty
  3. Disconnect all cables – Prevent parasitic drain
  4. Store indoors – Garage or basement at 50-70°F ideal
  5. Check every 2 months – Recharge if below 40%
  6. Full charge before use – Charge to 100% before spring

Frequently Asked Questions

Performance Questions

Q: How long does it actually last per charge?
A: 8-12 hours for typical trolling motor use (55-80 lb thrust at medium speed). Varies based on motor size, speed setting, and water conditions. Some users report 15+ hours with smaller motors.

Q: Does it really weigh 70% less?
A: Yes. A 100Ah lithium battery weighs 35-40 pounds. A comparable lead-acid weighs 110-120 pounds. That’s a 70-75 pound difference.

Compatibility Questions

Q: Can I use my existing lead-acid charger?
A: Absolutely not. You must use a lithium-compatible 36V charger. Lead-acid chargers will damage lithium batteries. This is critical.

Q: Can I mix lithium and lead-acid batteries?
A: Never. Don’t mix battery types. They have different charging profiles and discharge characteristics. Use all lithium or all lead-acid, never mixed.

Warranty Questions

Q: What’s covered under warranty?
A: Manufacturing defects, cell failure, BMS malfunctions, and premature capacity loss. Not covered: physical damage, water damage, misuse, and the wrong charger.

Q: How long is the warranty?
A: Typically 5-10 years, depending on model. Premium models often include 10-year warranties. Keep your receipt for warranty claims.
