Power up your RC drone or FPV quadcopter with this 18650 2000mAh 7.4V 15C 2S Li-ion battery. Unlike traditional Li-Po batteries, 18650 cells offer longer cycle life (500+ cycles), better thermal stability, and are more resistant to swelling. The 15C discharge rate provides reliable power for stable flight and responsive controls. The compact 70×37×19mm size fits most battery compartments. Built with grade A cells and multi-layer safety protection against overcharge, over-discharge, and short circuits.

⚠️ Important — Choose the correct plug type for your device: This battery is available in 9 different connector versions. Please check your original battery’s plug type before ordering. The plug types are NOT interchangeable.

Available plug options:

• JST Plug — Standard 2-pin connector for many RC drones
• SM Long cable — SM connector with longer wire
• SM short cable — SM connector with shorter wire
• EL-2P Plug — 2-pin locking connector
• 5500 Plug — 5500 series connector
• KET-2P Plug — KET 2-pin connector
• T Plug — Large Tamiya connector, standard for many RC cars
• SM-4P Plug — 4-pin SM connector
• Xiaotiangong Plug — Small Tamiya connector

Charging Instructions: Use only a charger designed for 2S Li-ion/Li-Po batteries (7.4V). Set charger to Li-Po mode with 2S (8.4V full). Recommended charge current: 2.0A (1C). Never leave the battery unattended while charging. Do not discharge below 6.0V (3.0V per cell). Store at 40-60% charge. If swelling occurs, stop use immediately. 18650 cells are more durable than Li-Po but still require proper care.

Battery Care Tips: 18650 Li-ion batteries offer longer lifespan than Li-Po — up to 500 charge cycles. Avoid over-discharge — land your drone when you notice reduced power. For maximum lifespan, allow the battery to cool before recharging. Store at room temperature away from direct sunlight. If the battery becomes hot, shows damage, or the wrapper tears, stop use immediately.
