Built with grade A cells and multi-layer safety protection against overcharge, over-discharge, and short circuits.

SM-3P Compatibility Note: The SM-3P connector has 3 pins. The middle pin is usually not connected, making this battery fully compatible with SM-2P (2-pin) devices as well. Please check your original battery’s connector before ordering.

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.
