✅ Why Our Warranty Stands Out

Unlike marketplace sellers with short buyer protection windows, we handle claims directly — no automated disputes, no endless back-and-forth.

🔋 90-day warranty is the industry standard for replacement batteries. Batteries naturally lose capacity over time — this normal wear is not covered. Warranty applies to manufacturing defects only.

Frequently Asked Questions

This 18500 battery is specifically designed for the Flywheel FT008 RC boat. It features a pre-soldered JST plug and measures 52mm × 18mm for a perfect fit. If your FT008 battery is draining too fast or not holding a charge, this is the correct replacement. Also compatible with other RC aircraft, quadcopters, and drones that use a single 18500 cell with JST connector. Please check your battery compartment size before ordering.

This 18500 Li-ion battery has a capacity of 1100mAh at 3.7V nominal. The 15C discharge rate delivers up to 16.5A of continuous current, providing reliable power for your RC boat. Full charge voltage is 4.2V. Always use a compatible Li-ion charger and avoid discharging below 3.0V to maximize battery lifespan. For reference, similar 18500 batteries on AliExpress sell for $3-5, while Amazon lists them for $7-10 including shipping.

Use only a charger designed for single-cell (3.7V) Li-ion batteries. Set charger to 3.7V mode with 4.2V full charge. Recommended charge current: 1.1A (1C maximum). Never leave the battery unattended while charging. Do not discharge below 3.0V. For maximum lifespan, store at 40-60% charge at room temperature when not in use. If the battery swells, becomes hot, or shows any damage, stop use immediately and recycle properly.
