If you are a newbie in the amazing FPV quadcopter world, probably you have started by buying the best 2020 Tiny whoop: UZ65

This incredible tiny whoop quadcopter includes 4 3.8V 300 mAH LiHV batteries.

It also includes a “regular” USB charger (if you can, get a better one). This USB charger has a two position switch to indicate if you are charging a LiPo (3.7V) or LiHV (3.8V) battery.

But the problem brings when you try to charge the batteries…

Where the hell is the label to indicate the battery type in charger PCB?

Since there was no response on Google, I decided to try shitting in both positions and then measure with the multimeter.

And the result is the following:

USB Charger Switch information

As you can infer from the picture, the charger is configured to LiHV (3.8V).

I hope this helps you if you are in similar scenario.

Time to burn some LiPos!
