🔋 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.

Power up your RC drone or electronic toy with this 14500 600mAh 7.4V 2S Li-ion battery. This battery uses two high-quality 14500 cells in series to deliver reliable power for your RC devices. The SM-4P plug provides a secure connection. Built with grade A cells and multi-layer safety protection against overcharge, over-discharge, and short circuits. CE and RoHS certified.
SM-4P Compatibility Note: The SM-4P connector has 4 pins. In most RC applications, only 2 pins are used for discharge (compatible with some SM-2P devices). Please check your original battery’s connector before ordering — SM-4P may not be fully compatible with all SM-2P devices. If your device uses a different plug type, you may need an adapter.
Charging Instructions: Use only a charger designed for 2S (7.4V) Li-ion/Li-Po batteries. Set charger to Li-Po mode with 2S selected — full charge voltage is 8.4V. Recommended charge current: 0.6A (1C). Never leave the battery unattended while charging. Do not discharge below 6.0V (3.0V per cell).
Battery Care Tips: Avoid over-discharge — stop using your device when you notice reduced power. Allow the battery to cool before recharging. Store at 40-60% charge at room temperature. If the battery swells or becomes hot, stop use immediately and recycle properly.

Frequently Asked Questions

The SM-4P connector has 4 pins (2×2 arrangement). In many RC applications, only 2 of the pins are used for discharge — typically the outer two pins. This means the battery MAY be compatible with some SM-2P devices, but compatibility is NOT guaranteed. Please check your original battery's connector pin configuration before ordering. For reference, similar 2S 14500 batteries on AliExpress sell for $5-9, and Amazon for $8-14. If your device uses a different connector, you may need to purchase an adapter.

This 14500 2S battery has a capacity of 600mAh and a rated voltage of 7.4V. It uses two 14500 Li-ion cells (AA-size, 14mm × 50mm) connected in series. Full charge voltage is 8.4V (4.2V per cell). Always use a 2S Li-ion/Li-Po charger. The battery is designed for RC drones, electronic toys, and other 2S devices. Never use a 1S or 3S charger — incorrect voltage will damage the battery.

Use only a balance charger designed for 2S (7.4V) Li-ion/Li-Po batteries. Key guidelines:
- Set charger to Li-Po mode with 2S selected — full charge voltage is 8.4V
- Recommended charge current: 0.6A (1C maximum)
- Balance charging is recommended for cell health
- Never leave the battery unattended while charging
- Do not discharge below 6.0V (3.0V per cell)
- For storage (over 7 days), charge/discharge to 3.8V per cell (7.6V total)
- Store at room temperature away from direct sunlight

If the battery swells or becomes hot during charging or use, stop immediately and recycle properly.
