Searched online for this question can't seem to find an answer. Coming from Rc 10th Scale Racing with 2s and 4s lipos i can charge by batteries 10 minutes or sometimes less right after main, and during practice i give it 5 minutes to cool down then plug in to charge.

Now as i'am new to drones these smart batteries is new to me. So my question is,

How long after can i recharge Fvp battery after a flight?

You can do it right after the flight. If the batteries are too hot they'll stop the charge because they're intelligent batteries and then they'll automatically start to charge when they cool off enough
