You do get extra capacity as Oscar's post has demonstrated. The extra voltage also gives you extra punch if you are using a racing drone. I have a Gens Ace charger that can charge LiHV batteries, I presume to a 4.3v per cell charge. However I am not sure I want to do that as I do not really need the extra capacity, and Oscar says the higher voltage may reduce the life of the lipo.
I discovered what "nominal voltage of 7.6v" on gaoneng lipos means. Gaoneng lipos with 4.2v per cell max have "nominal voltage of 7.4v", and the LiHV's with the 7.6 number means a max voltage per cell of 4.3v.
My smaller 3D planes seem to thrive on 2S lipos with a capacity >500 or 600 mah. One of my best 2S lipos (a 2S 950 mah turnigy graphene) is showing signs of wear (the charger thought a cell had gone over 4.2v and stopped - but in fact both cells were well below 4.2). I have just ordered two gaoneng 850 mah 2S 120C lipos from PhaserFpv, they are cheap and I have been pleased with my 650mah LiHVs (also cheap) which I charge to 4.2c per cell.
