Commercial Tandem Operations

Ideal for commercial operations offering tandem flights, where consistent power delivery and safety are paramount. The high-capacity design supports the increased power demands of tandem towing operations.

Step-Towing & Pay-Out Systems

Compatible with both traditional pay-in and modern pay-out winch systems ⇱. The regenerative braking capabilities work seamlessly with electric winch control systems for precise tension management.

Mobile & Portable Winch Units

Lightweight design makes these batteries perfect for portable winch systems that need to be transported to different launch sites. The compact form factor doesn’t compromise on power delivery. ⇱

Remote Launch Sites

Excellent for operations at remote locations where noise pollution is a concern. Electric battery powered winch operate much quieter than traditional gas-powered alternatives.

Power-Dense & Efficient

With high energy density, our NMC batteries deliver more power per kilogram, making them a cost-effective choice for performance-focused applications. You’ll get longer flight operations in a compact setup, helping reduce downtime and increase efficiency per launch.

Smart Safety Features

While NMC chemistry offers higher performance, our batteries include a smart BMS to manage temperature, voltage, and current. This ensures safe and reliable operation, even under demanding conditions, providing extra confidence during training and competitions.

Consistent Towing Performance

Unlike gas winches that can vary in power delivery, our batteries provide steady, predictable performance. This consistency helps instructors provide better training experiences and reduces student anxiety during launches.

Reduced Maintenance Requirements

Our batteries require virtually no maintenance compared to gas engines or lead-acid batteries. This means more time spent flying and teaching, less time on equipment maintenance.

Quiet Operation Benefits

Electric winches powered by our batteries operate much quieter than gas alternatives. This reduces noise complaints from neighbors and allows operation in more sensitive locations.

Custom Configuration Support

We work closely with clubs and instructors to design battery systems that match their specific equipment and operational needs. Our engineering team provides ongoing support throughout the project lifecycle.

Environmental Advantages

Zero emissions operation aligns with growing environmental awareness in the aviation community. LiFePO4 batteries are also fully recyclable at end of life.

Weather Independence

Unlike gas engines that can be difficult to start in cold weather, our batteries provide reliable performance across a wide temperature range [-20°C to +60°C]. This extends your flying season and reduces weather-related cancellations.

Q: I hear lithium batteries make winches lighter. How will this really change my flying day?
A: Beyond just easier lifting, a lighter winch system (thanks to lithium) means you can access more remote or challenging launch sites. Think less about vehicle access and more about the perfect spot. It could also mean quicker setup and more spontaneity for your flying sessions.

Q: Is the “silent ascent” with an electric winch that different? How might it affect my flight?
A: Many pilots find the near-silent operation of an electric winch, powered by lithium batteries, to be a game-changer. It allows for a calmer, more focused pre-flight experience, helping you connect with the air and your surroundings without the distraction of engine noise.

Q: Can lithium-powered electric winches truly make paragliding more accessible for me and my friends?
A: Yes! The portability and potentially lower operational costs (no fuel, less maintenance than gas engines) can empower smaller groups or clubs. You might find it easier to organize regular flying in flatland areas where previously it was too logistically complex.

Q: What exactly is a Battery Management System (BMS) in my winch battery, and why should I care?
A: Think of the BMS as the “brain” of your lithium battery. It actively protects your investment and ensures your safety by preventing over-charging, over-discharging, over-current, and extreme temperatures. This intelligence means more reliable power and a longer lifespan for your battery.

Q: Are these batteries just about power, or is there a “sustainability” angle I should consider?
A: Great question! Electric winching is inherently cleaner than gas-powered alternatives. When you charge your lithium battery with electricity from renewable sources, you significantly reduce your flight’s environmental footprint. Responsible recycling at end-of-life is also key.

Q: Lithium batteries for winches seem expensive. How can I justify the investment?
A: While the upfront cost can be higher, consider the total value. You’re investing in more airtime, potentially lower “fuel” costs (electricity vs. gasoline), less maintenance, and the sheer convenience and freedom these batteries unlock over many flying seasons.

Q: How many tows can I realistically expect from a single charge of my lithium winch battery?
A: This varies greatly depending on battery capacity (Ah), winch efficiency, pilot weight, glider size, and desired tow height. However, quality lithium batteries are designed for multiple tows, often enough for a good day of flying for a small group. Check your specific battery and winch manufacturer’s guidelines.

Q: My car has a 12-volt system. Can I charge my high-voltage (72V/80V etc.) electric paragliding winch battery from it?
A: While your main electric paragliding winch battery operates at much higher voltages, 12 volts source like your car battery can indeed be used to recharge it in the field. However, you’ll need a specific high-voltage battery charger that is designed to accept a 12V input (often via an inverter or a specialized DC-DC charger). This setup is great for off-grid convenience, but always ensure you’re using compatible and safe charging equipment to protect both your car’s electrical system and your valuable winch battery.

Q: If my winch battery is “smart” because of its BMS, does that mean I don’t need to worry about how I use it?
A: While the BMS offers significant protection, it’s not a substitute for responsible use. You should still follow best practices for charging, discharging within recommended limits, storage, and handling to maximize its life and ensure safety.

Q: How does the portability offered by lithium ion batteries impact the type of flying I can do?
A: It can open up new possibilities. You’re less tethered to easily accessible, vehicle-friendly launch sites. This could mean exploring hike-and-fly winch launches or setting up in more secluded, scenic spots that were previously out of reach.

Q: Will a quieter electric winch launch help me feel more connected to nature during my ascent?
A: Many pilots report exactly that! The absence of loud engine noise allows you to hear the wind, the birds, and experience a more serene climb, fostering a deeper appreciation for the environment you’re about to fly in.

Q: What are the key safety precautions I must take when handling and charging my lithium winch battery?
A: Always use the manufacturer-recommended charger, charge in a fire-safe area away from flammables, never charge or use a damaged battery, avoid extreme temperatures, and store it appropriately (often at a partial charge in a cool, dry place).

Q: How does the consistent power delivery of a lithium battery benefit my winch tow?
A: Unlike some older battery chemistries, lithium batteries (especially NMC) maintain a more stable voltage throughout their discharge cycle. This translates to more consistent and predictable pull from your winch from the first tow to the last.

Q: Can I charge my electric winch lithium battery using solar power when I’m off-grid?
A: Yes, absolutely! Many pilots combine their electric winch setups with portable solar charging systems. This enhances your autonomy and further reduces your environmental impact, allowing you to fly sustainably in remote locations.

Q: What should I do with my lithium winch battery when it reaches the end of its life?
A: Never dispose of lithium batteries in regular trash. They contain valuable materials and require specialized recycling. Look for local e-waste recycling centers or battery recycling programs that accept lithium-ion batteries.

Q: Beyond the battery itself, how does this technology influence the winch operator’s experience?
A: For the operator, it means less hassle with fuel and engine maintenance, a quieter operating environment (better for communication and instruction), and often a lighter, more manageable overall system. This can make the role of winch operator less strenuous and more enjoyable.
