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

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.”
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

Advanced Tips for Power Users
Maximizing Battery Lifespan
Pro tips from experienced users:
- Avoid 100% charges when possible – Charging to 80-90% extends lifespan. Only charge to 100% before long trips.
- Don’t discharge below 20% – While safe to go lower, keeping above 20% maximizes cycle life.
- Store at 50-60% charge – This is the ideal storage charge level for long-term health.
- Avoid temperature extremes – Keep battery between 50-80°F when possible for optimal longevity.
- 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:
- Clean thoroughly – Remove dirt, salt, corrosion
- Charge to 50-60% – Not full, not empty
- Disconnect all cables – Prevent parasitic drain
- Store indoors – Garage or basement at 50-70°F ideal
- Check every 2 months – Recharge if below 40%
- 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.
