There are some European standards and conventions which see a different connection (M26) used for high-oxygen diving mixes, which the official Apeks nitrox versions are likely to be.

It would make sense that the mass of the flywheel could double as a ballast block. If the flywheel is not gimballed then there would be significant gyroscopic forces enacted on the vessel such as yaw changes resulting in roll and/or pitch forces. Perhaps two or three flywheels, fixed in place with different orientations, would zero the net gyroscopic forces. If the flywheel could be used to stabilise the vessel, would that consumption of inertial energy adversely reduce the range of the vessel in rough seas?

There are still some active like Chakratec in Israel. But the targeted applications have narrowed down to cases where high power vs energy capacity (like ability to do a full discharge in less than 15mn) and where tens of thousands of cycles are needed. This is not what subs need. Otherwise it is just too expensive. Over time i have been impressed by the amount of beautiful engineering that has gone into these things, notably to make them spin faster (kinetic energy scales with speed squared, whereas it is just proportional to rotating mass), with carbon fiber rotors, frictionless magnetic bearings, vacuum chamber and as Cliff said failure management. Using them in a moving platform would not be good for bearings too.

I will be going this route!?The depth sounders normally have charts with them & the charts are continually being updated and with GPS, put you in location when you are on the surface.?If you find anything of significance like a treasure chest; you can go straight up to the surface & mark it with a way point on your maps. Also having the display enables you to see objects of interest below you.?Alan On Tuesday, March 30, 2021, 01:40:16 PM GMT+13, Jon Wallace via Personal_Submersibles wrote: Yes.? I want everything (or as much as possible, realistically) on my primary display and feel that I really only need a digital numerical representation of depth rather than the functionality of a fishfinder or side-scan sonar.? However, some traditional fishfinders have a NMEA output that can feed other displays/instruments.? It may turn out that such a fishfinder is an appropriate solution and in fact cheaper than a transducer specific to my needs.?

What is the thread size? Your drawing shows three conductors. What is the third one for, and what is its size? What is the available clearance between the corner of the battery and the pod ID? Looking at your drawing, I might be inclined to see if there would be any way to make a lower profile connection between the penetrator leads and e.g. some low profile insulated buss bars which could sit in either of the void spaces above or below the battery stack, and which would lead to a more convenient location to actually connect to the battery. Do you have a photo or drawing of the penetrator?

Try fitting the batteries past the threaded rod individually on an angle. Push them together down the end of the pod and bolt a piece of angle iron in to stop them sliding up & down the pod. Main thing is that you can't touch the pod with the terminals if they tip. It would take quite a bit of tilt to move them out of place. You would need to make a hoe type device to pull them out again. Maybe a pole either side with a protrusion to pull either side of the battery similtaneously.?Alan?Alan?
