Power up your remote‑control adventure with this high‑performance 16500 6.4V 800mAh LiFePO₄ battery. Designed specifically for the Weili 6‑wheel off‑road RC toy car and compatible with a wide range of 1:12, 1:14, and 1:18 scale RC vehicles. Built with two 3.2V LiFePO₄ cells in series (2S configuration), this battery delivers stable 6.4V output, providing consistent power throughout the entire runtime without voltage sag — giving your off‑road RC car sustained torque for climbing rough terrain, sand, and grass.
LiFePO₄ battery technology offers superior safety and long cycle life compared to standard lithium‑ion batteries. With over 500 charge cycles maintaining 80% capacity, this battery is designed for long‑term durability. Operating temperature range spans -20°C to 60°C for discharge and 0°C to 45°C for charging — suitable for outdoor year‑round use. Features built‑in overcharge, over‑discharge, overcurrent, and short circuit protection. CE, RoHS, and UN38.3 certified for safe transport and use. Fully charged voltage reaches 7.3V max, with a cut‑off voltage of 5.4V. For reference, third‑party retailers sell this battery for approximately £8.22 (≈$10.50).
Important Compatibility Note: Please power down your device and check your original battery before ordering. Ensure the SM‑4P plug connector matches your device — the red wire is positive “+”, black wire is negative “-“. This battery is compatible with Weili 6‑wheel off‑road RC toy car, 1:12 four‑wheel drive rally cars, off‑road trucks, and various RC models requiring 6.4V LiFePO₄ battery. Always verify the voltage requirements of your RC vehicle — never use a 6.4V battery in a device designed for 3.7V or 7.4V systems.
Important Safety Information for LiFePO₄ Batteries: Only use a dedicated LiFePO₄ charger (charger voltage 7.3V max, charge current 400mA) — NEVER use a standard Li‑ion charger (4.2V per cell) as this will damage the battery and may create a fire hazard. Always unplug the battery from the ESC and remove it from the RC vehicle before charging. Do not disassemble, short circuit, or dispose of in fire. Rechargeable batteries can not be overcharged or over‑discharged.
Battery Care Tips: Avoid full discharge — recharge when battery level drops below 20%. Do not expose to high temperatures or direct sunlight. New batteries require 3‑4 full charge/discharge cycles to reach optimal capacity. Always use a dedicated LiFePO₄ charger with the correct SM‑4P connector or a compatible adapter. If you don‘t use the battery for a long time, store it in a dry and cool place at approximately 40%‑60% charge and recharge fully once every three months to prevent deep discharge. If you notice swelling or overheating, stop use immediately.
