I had no idea!
Do I need an adapter for plugging into the drone or is it plug & play?
I have a 4s car that would promptly burn up with 15+ volts so thought the same for the H. Thanks for the insight.
You do not need an adapter to install the battery in an H. However, this battery will not fit in your charger. It would be better to sell this battery or return it to get the correct one for the H. Otherwise you will need to purchase a new H Plus charger.
Really have to wonder about the long term viability of a company that changes parts between every model to make sure nothing is compatible.
The 'H' was supposed to be a modular flying system, with development.... nope... new model, buy every thing you have already... again. and again.
