I guess I should've been more specific. I was thinking instead of using the 7950TH to switch to my 7955TG which isn't HV. In that case would I still need an external BEC on 2s? And is it ok to put say 3 x 4600uf 10v caps in series to be closer (well actually way over) to BrianG recommended 10,000uf 10v? Thanks BrianG for a reply.
