I got my Spark today! 2 days before FedEx had it scheduled to deliver. Loving it so far. Have flown 2 packs twice each. But my question is, the hub seems to charge one battery before it moves to the next? Is this the expected charging procedure? I'd like for it to charge all 3 at once. I ordered 2 additional batteries but they have not shipped yet. Only getting 30 mins in the air and then waiting a couple of hours is boring. Lol

Spark charger charges all batteries simultaneously. Mavic charger does one then the other and so on.

It only charges them when the temp is cool enough. Perhaps one was hotter than the other and it took longer to start charging.

I believe you may be right. I flew them both again and now they are both indicating that they are charging this time.

Always cool your batteries before charging. Never fully drain. They should last a long time.
