LiHV packs? They have a natural built in safety margin when charged to BRCA requirement of 8.4V instead of 8.6-7V. And you'll never get to the full quoted capacity as you are charging to a point under its peak voltage and capacity. LiHV (High Voltage) are 4.35V per cell vs the 4.20V of the standard Lipo, and typically have a higher energy density than the equivalent Lipo pack.
Cell production factories have mostly switched now to producing the LiHV formulation cells, and so the RC battery assemblers will just use the stocks that are readily available, and mark them up as LiHV.

I imagine it wont be too long before the 8.4V charge limit it re-addressed by the sanctioning bodies once Lipo packs are no longer common, and everyone has switched to LiHV. I've been running LiHV now for two seasons, charging of course to 8.4V, and have found them to be excellent.
