Powering an electric winch

As the title says.

I have recently acquired a Dutton Lainson TW9000 electric trailer winch to fit as a winter project. The winch comes with a loom to fit to the vehicle to provide a supply direct from the vehicle battery, I'm not particularly comfortable with this for various reasons:-
  1. I don't want heavy cables running the length of the Disco connected directly to the battery, this is asking for trouble.
  2. Unless I put an isolator in 1 above, I have a permanent live which will cause allsorts of corrosion issues.
I'm leaning towards a dedicated battery mounted close to the winch on the trailer, charged from the towing electrics. I'm toying with a waterproof box (Stainless naturally) sealed, with a vent pipe brought up to high level. Integral IP68 isolator.

Discuss

Don't forget to pop an electric fence energiser unit inside the battery box, a shocking surprise for any would be thief trying to steal that stainless work of art while you're at sea.

Vented battery? Suggest glass mat battery charging off trailer socket is good idea I happen to know where you can get IP rated while unmated connectors not cheap ( most are only ip rated when mated)

At least it wouldn't need to be a IP68 depending where you put it.

Mmmm...

How easy is it to make a stainless box thats IP68. Will the box not flex when under water and so distort the seal?

How tall do you vent the pipe... If spray gets in the pipe will the water sit in the bottom as not drained?

i was just going to put a battery in boot and charge it from a cig lighter charger in boot (under 5 amps) when underway and leave it on a trickle at home. doing this is the same as 14pin electrics in terms of charge current.

if you have the room then leaving it in the boot with a charge controller relay is also another option ofcourse.

granted it is another thing to forget though but i was worried about it looking very attractive to wanna be scum bags. winch can be off in seconds with couple of spanners and so could a battery box.

Hi Dave ,,,, like your idea of a 'sealed' trailer mounted battery box assuming the nose weight change won't cause you too much work balancing that super smart trailer. It also solves the problem of recovery anywhere where you have to use a 3rd party tractor and your power is on your own vehicle in the car park! Probably not an issue with a disco though :-)
To be fair, mine is run front to back through he chassis on my XC70 and I have left trust in the fuseable links DL supply in case of shorting. No issues over 5 years with cable corrosion. I was mildly miffed when Volvo moved the battery from the boot to the engine compartment in 2008. My first one was ace to install with a 18" long run to the Anderson !
You could probably pay for the cost of your winch by selling your stainless trailer mounted battery boxes 😊

I'm probably going to fit one of these inside a custom built S/steel box. I was thinking about a Bulgin plug & bulkhead socket fitted to the box to allow on/off vehicle charging. I'd be interested in a link to the connectors you mentioned. 99% of the time, the winch end of the trailer never gets near the water. It's only if we have a tricky recovery or launch at Ty Calch with the tractor do we get up to the drawbar.
