Assuming you are talking about a battery for an FPV headset or goggles, the process is pretty simple. Most batteries will come with a charging cord that plugs into any standard USB port. Once plugged in, the LED indicator on the battery will usually change color to indicate it is charging. For example, many LiPo batteries will turn red when they are low on power and green when they are fully charged. Some batteries may also have a multi-colored LED that changes color as the charge level increases.
It is important to note that you should never leave LiPo batteries charging unattended as there is always a risk of fire if something goes wrong. If possible, it is best to charge them inside a fireproof bag or container just to be safe. With that said, here are some general tips for charging FPV goggle batteries:
- Make sure the battery is compatible with the charger you are using. This seems like common sense, but using the wrong charger can damage your battery and/or cause a fire hazard.
- Do not overcharge your battery! Most LiPo batteries have built-in protection against this, but it is still good to keep an eye on things while charging just in case.
- Do not charge your battery too quickly. Again, most LiPos will have built-in protections against this (called balancing), butCharging at too high of an amp rate can still damage your cells and shorten their lifespan significantly
