Revolutionize Your Start: Ditch Lead-Acid for Smarter, Stronger Lithium Power
Meet the next generation of starting power. Our 12V 20Ah LiFePO4 Cranking Battery is engineered to replace bulky, short-lived lead-acid batteries with superior lithium technology. Designed for demanding starts in cars, trucks, boats, and RVs, it delivers instant, high-current bursts (200 CCA) while offering deep-cycle capabilities and an incredible 4000+ cycle lifespan. With integrated smart Bluetooth monitoring, built-in self-heating (optional), and a maintenance-free design, it's the reliable, powerful, and intelligent choice for any engine.
High Current Discharge (200 CCA): Provides a stronger, more reliable surge of power to start your engine instantly, even in cold weather.
Fast Charging: Recharges in hours, not days. Get back on the road or water faster than with any lead-acid battery.
Low Internal Resistance: Delivers maximum power efficiently with minimal voltage drop, ensuring consistent starting performance.
Intelligent Safety & Control
Smart Bluetooth BMS: Monitor battery voltage, state of charge, and health in real-time from your smartphone. No more guessing.
Comprehensive Protection: Built-in BMS guards against over-charging, over-discharging, over-current, short circuits, and provides cell balancing for ultimate safety and longevity.
Ultra-Safe LiFePO4 Chemistry: Inherently stable and non-combustible, offering complete peace of mind even in extreme conditions or accidental mishandling.
Longevity & Reliability for the Long Haul
10+ Year Design Life: Built with Grade A LiFePO4 cells for exceptional durability.
Over 4000 Deep Cycles: Outlasts lead-acid batteries by 5-8x, making it perfect for dual-purpose starting and deep-cycle use.
Optional Self-Heating Function: Ensures reliable charging and performance in freezing temperatures, solving the #1 challenge for batteries in cold climates.
Eco-Friendly & Maintenance-Free
Zero Maintenance: Never add water or check terminals for corrosion again. Install it and forget it.
Lightweight & Compact: At only ~3.5kg, it's a fraction of the weight of a lead-acid battery, making installation and handling easy.
Environmentally Friendly: Non-toxic materials and a vastly longer lifespan reduce environmental impact.
Application Scenarios
For Marine & Fishing Boats
The ideal marine cranking lithium battery. Start your outboard engine reliably and power your fish finder or small trolling motor all day. Waterproof and corrosion-resistant for the harsh marine environment.
For Cars, Trucks & SUVs
Upgrade your vehicle with a lithium starting battery that's lighter, more powerful, and lasts the life of your car. Perfect for daily drivers and vehicles with high electrical loads.
For RVs, Campers & Off-Grid Setups
A dual-purpose powerhouse. Crank your RV engine powerfully, then use its deep-cycle capacity to run lights, fans, or small appliances. Bluetooth lets you manage power use wisely.
For Powersports & Specialty Vehicles
Deliver extreme cold-cranking amps for ATVs, UTVs, and classic cars. The compact size fits tight spaces, and the lightweight design boosts performance.

Frequently Asked Questions (FAQ)
Is this battery a direct replacement for my lead-acid battery?
In most cases, yes. It is a direct drop-in replacement in terms of voltage (12.8V). Its lighter weight, smaller size, and higher power make it a superior upgrade. Always check your vehicle's charging system compatibility.
How does the Bluetooth app work?
Download the app (our standard or your custom-branded version), pair it with the battery via Bluetooth, and instantly view real-time data like State of Charge (SOC), voltage, current, temperature, and cycle count.
Why is the self-heating function important?
Standard lithium batteries cannot be charged safely below freezing (0°C/32°F). The optional self-heating system warms the battery internally, allowing for safe and efficient charging in cold weather, a critical feature for winter use.
Can I use this battery for both starting and running accessories?
Absolutely. This is a key advantage. Its high CCA ensures strong starts, and its LiFePO4 chemistry allows for deep, cyclic discharge to power accessories without damaging the battery, unlike traditional starter batteries.
What charger do I need?
You must use a lithium-iron-phosphate (LiFePO4) specific charger (14.6V). Using a lead-acid charger will not charge it fully or correctly. We offer compatible chargers as an optional accessory.
What is your warranty policy?
We offer a robust warranty on all our LiFePO4 batteries, reflecting our confidence in their quality and long design life. Contact us for specific warranty terms.
