Ive seen a few like that, but im not keen on it myself. i do realise space is at a premium, and it will get trashed where its at now. Its one of the pressed metal types, so hoping it will bend back if hit!

Stick on type is not mot legal
But i have one on :whistle:

My stick on is legal font correctly spaced and certified reflective background.....and in a position as near to vertical as possible.....not part of the mot....but regulated elsewhere.

No postcode of the maker is it's only "crime"

I have a 13000 lb winch.. stock battery (45amp) will get destroyed if you try winching under load with it as not enough cca for winch.
The winch takes 80 amps with no load, about the same as the starter motor?
I fitted a 100 a/h battery, cca of 750, connected a 75a cable from starter battery to 100a/h battery with isolator switch.
Works brilliantly.
Alternator is 75 amps, so in a perfect world could fully recharge both batterys in 2 hrs from flat, but i know it does not happen like that.

That's just wrong. Plain and simple.

The standard battery in a Jimny is fine for occasional winching. And with a 13000 lbs winch you'd have to be seriously bogged down before the winch starts drawing high amps.

So no, nothing gets destroyed.
Used the standard battery with a Goodwinch TDS 9.5c many times before I upgraded with a better battery.

Tom dk, do you actually have any idea about the power we are talking here? We are not talking 80 to100amps for a few seconds to start an engine, but 5kw for a 13500 winch, or around 416 amps under load for a lot longer than starting an engine..
With a stock battery the plates will heat up and buckle dramatically until total failure. There is a reason that these winches state a minimum CCA of at least 650 amps. Stock 40 amp is around 320 cca.

What your saying is like powering a 3kw electric kettle from lighting cable , yes it will work, until it melts !

I operated my winch with no load, engine running and only stock battery and you could hear the massive hit the car was taking, and thats with the boost from the alternator helping.

There you have it Riccy, two "opinions" Google it and do some research and you will be able to make your own conclusion !
