Xantrex 36V 50Ah Lithium-Ion (LiFePO4) Battery Product Description
Unlock Superior Performance with Advanced LiFePO4 Technology
Imagine powering your trolling motor through endless days on the water without the constant worry of battery failure or excessive weight slowing you down. This 36V 50Ah LiFePO4 battery steps in as a direct upgrade for traditional Group 31 lead-acid setups, delivering compact power that punches way above its size. Fishermen, RV enthusiasts, and fleet operators alike rave about how it transforms their setups—lighter loads mean better fuel efficiency, and that marathon cycle life keeps you going season after season.
Crafted with UL1642-certified cells and layered safety protocols, it's built to thrive in the unforgiving world of marine vibrations, road bumps, and temperature swings. Whether you're chasing bass at dawn or hauling cargo cross-country, this battery's robust BMS (Battery Management System) guards against overcharge, deep discharge, and thermal runaway, making it one of the most reliable options out there.
More Power, Fewer Replacements: The Cycle Life Advantage
Lead-acid batteries tap out after 400-500 cycles, but this LiFePO4 powerhouse pushes up to 4,000 full cycles under normal use. That translates to years of dependable service before you even think about swapping it out. Its exceptional energy density crams more usable power into the same footprint, freeing up space in tight battery compartments and reducing overall vehicle weight for smoother handling and better range.
| Feature | LiFePO4 (This Battery) | Traditional Lead-Acid/AGM |
|---|---|---|
| Cycle Life | Up to 4,000 cycles | 400-500 cycles |
| Self-Discharge (Monthly) | 3% in Sleep Mode | Up to 20-30% |
| Charge Temp Range | Up to 55°C (131°F) | Limited, risk of damage |
| Weight Efficiency | High power density | Bulky and heavy |
Intelligent Features for Real-World Demands
- Sleep Mode Mastery: Kicks in after 10 days of no activity, slashing self-discharge to just 3% SOC per month (from 12.5% normally). Perfect for off-season storage—your battery stays primed without babysitting.
- Extreme Temp Resilience: Charge confidently in scorching heat up to 55°C/131°F, and an optional heating blanket keeps it performing in frigid conditions outside the cabin.
- Bluetooth Monitoring: Pair with the Xantrex app on your phone to track SOC, spot faults in real-time, and even remote toggle on/off. Stay ahead of issues before they strand you.
- Built-In Protection: Self-managing BMS handles high/low temps, faults, and more, with remote fault signaling for peace of mind.
These aren't just specs—they're game-changers for anyone tired of flat batteries ruining a perfect outing.
Versatile Power for Demanding Lifestyles
From the gentle rock of waves to the rumble of diesel engines, this battery shines across industries:
- Marine: Powers trolling motors silently and steadily, letting you fish longer without the drag of heavy lead-acid packs.
- RVs: Keeps lights, fridges, and inverters humming through remote campsites, with Bluetooth checks from your lounge chair.
- Heavy-Duty & Work Trucks: Handles fleet demands, reducing downtime with its marathon cycles and quick recharges.
- Specialty Vehicles: Custom rigs and off-road beasts get lightweight, high-output reliability.
Users report cutting battery maintenance by half, with one captain noting it "saved my season after a lead-acid flooded mid-trip."
Certified Safety You Can Trust
Backed by UN/DOT 38.3 Lithium Ion certification, it meets rigorous transport and safety standards. Redundant safeguards and premium cells ensure stability even in bumpy marine or overland adventures—no venting, no spills, just solid performance.
"Switched to this for my bass boat—lighter, lasts forever, and the app is a lifesaver for monitoring during tournaments." – Satisfied Angler
Frequently Asked Questions
How does the Sleep Mode work on this LiFePO4 battery?
After 10 consecutive days of inactivity, it enters Sleep Mode, dropping self-discharge to 3% State of Charge per month from the standard 12.5%. Any charge or discharge resets the timer, ideal for seasonal storage.
Can I charge this battery in hot environments?
Yes, it supports charging up to 55°C (131°F), making it suitable for extreme heat without risking damage—far beyond most lead-acid options.
Is Bluetooth connectivity easy to set up?
Absolutely—simply connect via the Xantrex app on your smartphone to monitor SOC, view faults, and control remote functions effortlessly from anywhere nearby.
What's the cycle life compared to lead-acid batteries?
This battery offers up to 4,000 cycles, about 8-10 times more than typical lead-acid or AGM batteries' 400-500 cycles, for dramatically longer service life.
Does it fit standard Group 31 compartments?
Yes, designed as a drop-in replacement for lead-acid Group 31 batteries, perfect for trolling motors and similar marine or vehicle setups.
What safety features does the BMS provide?
Includes self-protection against overcharge, over-discharge, extreme temperatures, short circuits, and faults, with remote monitoring capabilities.
Is it suitable for marine trolling motors?
Definitely—its high power density, vibration resistance, and long runtime make it ideal for fishing boats and other marine applications.
36V 50Ah Lithium-Ion (LiFePO4) Battery
High cycle Lithium-Ion (LiFePO4) battery designed to fit into existing lead acid Group 31 battery scenarios such as powering trolling motors for fishing boats.
More Power in Less Space
The Xantrex Lithium-Ion Iron Phosphate (LiFePO4) battery used UL1642-certified cells. Equipped with redundant safety features, it is the safest in the market today. Specifically designed to withstand the harsh operating environments of mobile and marine applications, the battery lasts up to 4,000 cycles compared to a traditional lead acid or AGM battery, which typically lasts 400-500 cycles. It offers exceptional power density and is also available with a heating blanket option if the installation is outside the main cabin.
Sleep Mode: Xantrex Lithium-Ion Iron Phosphate batteries self-discharge at 12.5% State of Charge (SOC) per month during regular use. After 10 consecutive days of inactivity, the battery switches to a low-power mode, reducing the self-discharge rate to 3% SOC per month. Any charge or discharge activity will reactivate the battery, resetting the 10-day counter. This extends the battery life during periods of non-use.
Sleep Mode
Reduces self-discharge to 3% from 12.5% State of Charge per month after 10 days of inactivity, enhancing battery life.
