Neither does it at 200 bars or even 100 bars due to Z factor, it simply rises and becomes more noticable (1.19 at 300 bar? I can't remember)
But how it was phrased sounded like it's impossible to get more gas into a tank above 240.
Suggested 02 Bank Storage Bottle?

I get back from a 1hr O2 RB dive having used 30b from a 2l tank, that's 435psi from a15cf tank pumped to 3500psi

The OP is talking about transfilling on trips into an Al13...AL13?
J (50 litres) is delivered at 220 bar here, so around 388 cubic feet.
I was talking about having a bank of O2 that even without a booster can last 3-6 months, not a deco stage.
You can get 300 bar in Europe, but it's problematic, expensive, not available from everywhere, not my supplier anyway.
I would generally stay away from 300 bar O2 in hobby environment anyway. 220 is scary enough.
It sounds weird that bulk gas suppliers wouldn't have 220 bar bank tanks available, that's how it's produced anyway.
The subject of the thread was a bank tank.
I believe the closest equivalent to our J on your side of the pond is the S tank, so maybe ask around for an S of O2.
Our 50L is a "T" which holds 300cf and weighs north of 150lbs empty and nearly 200lbs full. It also takes up half of a pickup truck. That's not something you carry around as a transfill bottle into an AL13 even if the gas supplier provides them (which is unusual depending on region)
