induction charging and balancing?

maybe i could search better but not seeing anything on the site related

tell me how possible this is and where my science is right or wrong or missing:

could you transmit from one transformer connected to 120v AC on the wall, and an air gap, small as could be, to many other inductors and each would be connected to different battery cells, and transform to 4 volts and get even a small current, or maybe reduce the huge current, and the cells would all sit at 4 volts on the charger while I slept? and a rectifier in there. what else?

with this maybe.

i'm back spamming my own thread dying to hear back from someone about if this could work


these are two bucks!:

the dream is 12 of these, hooked up to separate cells, and all sitting on maybe if I'm lucky one big transmitting coil. The dream is to charge and balance at the same time. what you think?!?!?!?!?

maybe the Qi pad wouldn't work for multiple stacked. I don't understand how it works to begin with as it's a transformer really but the coils aren't on the same core. totally flat.

Good idea!
But, maybe it is only practical for small capacity packs.

The problem with these systems is they are somewhat inefficient. Making it wireless causes some power loss. If you can plug it in, that's generally the way to go, from an efficiency standpoint.

but inefficiency isn't a problem as long as it doesn't get too hot, the waste heat will just heat the room and is cheap electricity. I assume these chargers have a cv and cut off so you could leave it on these inductance chargers all night.

actually the part i linked doesn't have any features to make the charge a regulated supply and it's in the phone that this is done. so if you were to just use those inductance coils you'd likely have to add the lipo single cell charger thing as well. Unless you went without those regulators and then...maybe set the voltage a bit low for the charge, at 4 volts maybe, and it'd be good.
