Using these battery straps is easy. First, choose the right size based on your quad's size and battery capacity. Wrap the strap around your battery and secure it using the metal hooks. Make sure it's tight enough so the battery stays in place during flight. For non - slip straps, you'll notice they hold well but handle them gently as they're not as strong as nylon. When it comes to nylon webbing straps, they can withstand more force but may not grip as firmly. To maintain your straps, keep them clean. Avoid getting them wet for long periods as it could damage the materials. If you notice any signs of wear, like fraying or weakening of the hooks, it's time to replace the strap. That way, you can keep your batteries safely in place and your quad flying smoothly.
