One problem with the HV that will pretty much always steer me away from it: the BEC operates off of only one of your two battery packs. This means it drains that pack faster, which essentially removes the possiblity of charging both packs together without heavy cell equalizing from the balancer.

I haven't looked into it, but I suppose you could bypass this by plugging both packs (or a single large pack) into the non-BEC side, and powering the ESC with a RX pack or UBEC. But even still, I'd much rather spend my money elsewhere...
