Well, there's really no reason why a voltage that's well with the nominal range of 13.8V, pre internal regulator reduction in rig would be problematic at long as it's stable generall, so 11V isn't a voltage on that basis where you'd expect issues.
After all, the voltage regulation should be able to handle 10-15V DC as typically transportables often are used as mobiles as well or use a domestic vehicle's DC supply for extended ops.
If it can't, then the circuitry involved is pretty much not fit for purpose.
It's when you're really going for broke chasing how as to how low can you go and still operate, as I've known plenty who've chased that goal, and you hit issues.
It's less of an issue with equipment using an internal battery as a sink, as (provided the battery is in good order and has at least a minimal level of charge to meet Tx demand under Tx use) as the voltage operated at internally is based usually on the battery supply voltage - the external supply in that scenario becomes more of an available higher current source than the source of supply voltage.
But it's worth being aware of this stuff because until you realise how the internal supply is configured, nothing is absolute that one case applies and not the other.

I agree on the 11 volts.? I run my unit at 11.1 without any problems and
it seems to run cooler.
