Interconnects for battery to thruster

[Sandworm3434]

Sorry for what is hopefully an embarrassingly simple question for you:

I need to connect a waterproof battery to a waterproof thruster. I’d like to use those rubber pressure interconnects that force close under pressure. hydroseal RMC?

Ideally, I’d like to do the least work (risk of error) and have both the battery and the thruster directly connect to each other via this RMC. No soldering or manual waterproofing ideally.

Can you suggest some products keywords that will be compatible?

I only need a small 12v battery and a small 12v submersible thruster. It only needs to drag 4kg 3km, so a 1kg lithium battery or maybe lighter I expect to be be enough.

How do you intend to fuse the hot?

I’m a bit confused here. If you need a waterproof setup; you still need to wire it properly. So, some ‘manual’ effort is required.

Soldering on a boat is essentially not done on electrical connections and crimping is the standard.

Waterproof is not necessarily the same as submersible. Just about any non marine metal part that touches water or is enclosed in a slowly permeable cover might corrode. Regular wiring might have to be sealed away from Water contact , like what is done with troll motors. Generally, Water corrodes, and salt water (or even the Salt Air Vapors) corrodes absolutely. Battery size varies tremendously, depending on how fast the 4 kg/ 3 km needs to be dragged! Do you have one week or 1 hour to go the 3 km?

The simple answer is you use a IP6K9K or MIL-ST- 810 512.5 rated connector.
The complicated answer is you tell us the specifics of the setup, because no immersion rated connector is worth anything if water can find a way elsewhere into the system.
