✅ 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.

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 6 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-2P Plug — 2-pin SM connector
  • SM-3P Plug — 3-pin SM connector (middle pin unused, compatible with SM-2P)
  • SM-4P Plug — 4-pin SM connector
  • EL-2P Plug — 2-pin locking connector
  • Xiaotiangong Plug — Small Tamiya connector

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: 0.7A (1C). Balance charging is recommended. Never leave the battery unattended while charging. Do not discharge below 6.0V (3.0V per cell).
Battery Care Tips: 14500 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. 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.

Frequently Asked Questions

This 14500 2S 7.4V Li-ion battery is compatible with RC drones, FPV quadcopters, and RC cars that fit a 55×28×14mm battery compartment. The 14500 cell size (AA-size, 14mm diameter) offers a compact form factor. Most importantly, you must select the correct plug type for your device — available options include JST, SM-2P, SM-3P, SM-4P, EL-2P, and Xiaotiangong. The SM-3P connector (3-pin) is compatible with SM-2P devices as the middle pin is typically unused. Please check your original battery's connector before ordering. This is a 2S pack — NOT for 1S (3.7V) or 3S (11.1V) systems.

The plug type determines compatibility with your device's battery connector:
- JST Plug: Standard 2-pin connector for many RC drones
- SM-2P Plug: 2-pin SM connector
- SM-3P Plug: 3-pin SM connector (middle pin unused, works with SM-2P)
- SM-4P Plug: 4-pin SM connector
- EL-2P Plug: 2-pin locking connector
- Xiaotiangong Plug: Small Tamiya connector

These plugs are NOT interchangeable. SM-3P is backward compatible with SM-2P devices. Please check your original battery's connector before ordering.

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: 0.7A (1C). Balance charging is highly recommended to keep both cells equal. Never leave the battery unattended while charging. Do not discharge below 6.0V (3.0V per cell). 14500 cells can handle up to 500 cycles with proper care. For maximum lifespan, store at 40-60% charge at room temperature. If the battery becomes hot or shows damage, stop use immediately.
