Best waterproof quick-release electrical connectors?

[Kelpie]

What sort of connector should I look for to carry say 100A at 12v DC, that will be reliable and waterproof but easily disconnected by hand (and yes I know it would be a very bad idea to make or break such a connection whilst live).
There's plenty of choice at the 20A sort of power rating, but I'm not sure what's available for higher power.

Application is for a trolling motor and its battery. They're supplied with crocodile clips but I'd like to upgrade to something more robust. I also want to be a be able to charge the battery without taking it out of the dinghy...

I use Andersen Power Pole connectors, spelling may be wrong. for that sort of current.
Not exactly water proof, but they survive.

I also use Anderson Power plugs on my removable boat winch attached to the front tow bar of my 4x4 and as survived for several years.

The power connectors are soldered rather then crimped to try to prevent corrosion in the cable connection

Another vote for Anderson connectors. Not even slightly waterproof really but very easy to remove the terminals from plastic housing to clean off any corrosion.

Anderson, as mentioned above, is a good choice, it is possible to add some waterproofing too: Anderson Connector Accessories | 12 Volt Planet

I'd search trolling motor connectors. Marineco and others make them up to some pretty high ratings. And they are meant for marine use and are waterproof.

Try Seaeye Marine and their "Metal Shell Connectors".
Professional quality and never fail down to -1000m.

Thanks all, I'd never heard of Powerpole connectors, looks like they might do the job.

Didn't see a price, but they *look* expensive!

 

[jamie N]

Yup, and I don't know 'how' expensive as it's always a 'company bought' item. However, even though it'll be way over the top for your needs, it'll work.
In truth, there'll be better alternatives which will always require a bit of maintenance that are far cheaper I guess.
I put it out their with some glibness, for which I should apologise.
