I know this is a fairly long thread, but if I remember correctly no one found a satisfactory solution using 5S, the only thing I can say is why not buy two 3S Hyperion if they are what you are set on, personnaly I run an AXI motor on a 15 x 10 on 6S, but I have five batteries so don't need to re-charge at the field, also I never charge at any more than 0.5C that way my batteries seem to last a lot longer than most of my peers.
