Wireless chargers in series?
It's possible, but here are some ideas to make it work:


10A charge is a lot. You probably don't want to play with over 120W (that is, 12V times 10A into the battery is a 120 watt charge) if your electronics experience is limited to Arduino stuff. Things will get hot. There will be sparks. Cables have to be big. Stuff will fail. 2A is a good place to start your design at - it's not an unusual basic 12V charger rate, so just do your calcs to ensure the charge time is adequate. 2A @ 15V (which is a safe estimate of the charge voltage of a 12V battery) is 30W, so 8 of the 5W qi chargers should get you over the line.
As @alex.forencich says, don't series them all. Make two sets of 4 in series and put the two sets in parallel. That'll give you 20V @ 2A. That's plenty of voltage headroom to drive a charger.
Have you considered replacing the wireless charges with contact pins or brushes? Since the wireless chargers will only work when the dome is parked, you could do the same with contact pins or brushes that make contact in the parked position. Much, much higher efficiency and much simpler, but at the loss of some coolness factor. I think you'll have a lot of trouble getting the chargers to align - they're designed to come close together and then magnetically snap into perfect alignment. Works fine when you have one attached to something light. But is not going to work so well if you have to align several of them, all rigidly fixed in space.
A charger that takes DC is not a problem. Even the chargers that take AC just convert to DC internally before supplying the actual charger. Finding one that meets your specs is always a mission, but technically speaking it's not a problem.
