Are you remembering to turn on the ventilation units? They give you extra air at the cost of electricity, gets you an extra hour or two if the engines are going, and much, much longer if the engines are still.
Ventilation switch is in the diesel engine compartment.
Ventilation off on a just submerged boat
And on, engines still:
So toggling the vents on and off can buy you a lot of needed time underwater, but you're still operating on a limited budget, as it's all off the batteries. Just be careful as they do generate noise.
