Frequently Asked Questions

This 852540 battery is compatible with X5C, X5SW, FY550, HJ818, HJ819, M68 RC drones and similar quadcopters that fit a 45×25×8.5mm battery compartment. The 25C discharge rate provides ample power for flips and aggressive flight. Most importantly, you must select the correct plug type for your drone — available options include JST, SM, XH2.54, and PH2.0. Please check your original battery's connector before ordering. PH2.0 is the most common on X5C/M68 models.

The plug type determines compatibility with your drone's battery connector:
- JST Plug: Standard red 2-pin connector for many RC drones
- SM Plug: Small 2-pin connector for micro drones
- XH2.54 Plug: 2.54mm pitch connector
- PH2.0 Plug: 2.0mm pitch connector — common on X5C/M68/FY550 drones

These plugs are NOT interchangeable. Please check your original battery's connector before ordering. If unsure, select PH2.0 as this is the standard for X5C/M68.

Use only a charger designed for 3.7V Li-Po batteries. Set charger to Li-Po mode with 3.7V nominal (4.2V full). Recommended charge current: 650mA (1C) — do NOT exceed 1.3A. Never leave the battery unattended while charging. For maximum lifespan, land your drone when you notice reduced power to avoid over-discharge (below 3.0V per cell). Store at 40-60% charge at room temperature. If the battery swells, becomes hot, or shows any damage, stop use immediately and recycle.
