I've just had to read 14 pages and there is no part number
Standard Alternator AFAIK!! you could PM him & ask, just to be on the safe side..

are these any good for dual batteries? looking at fitting a 2nd bat to power an inverter and whatever is attached to it!

That looks to be the same as the durite, 3 wires. Battery 1+ battery 2+ and negative. Simple and reliable. Same sort of price as the durite too.
There is also the question of what type of battery to use for the 2nd.
For winching and other similar short term heavy loads, probably a car battery with a high cranking output.
For an inverter, lights, coolbox, or other loads that will be on for some time, probvably often with the engine off, you need a deep discharge type that will give longer time power and not be so upset if it goes flat!

Got another battery which is the same as my current one today!!
Gonna buy the caravan one as its the same as the one i posted and with postage works out 11 quid cheaper so hey ho!!
Now to fit some kind of bypass switch, so you could use the 2nd bat if the 1st one went faulty, would you just link the two positives together via an isolator?

Just brought the durite one from ebay for £43...
Was going to go for the caravan one but i noticed it said cuts in at 13.7volts and out at 12.8 where the durite cuts in at 13.3 and out at 12.8, so just incase my alt doesnt play nicely it should still go that little bit more..

2-3mm should be fine.
All depends on your spots obviously. I'm running led so they draw less current.
Take the wattage of the lights on the circuit. Say 100w. Divide that by 12. That's your voltage and dividing it by voltage gives you amps. Amps=watts/voltage. Making it 12 not 12.5 builds in a bit of extra.
Then goto someone like altec automotive and peruse their wire. 3mm is good for approx 35amps. That's north of 400 watts.

it would but its not perfect, you could end up with 2 of the 3 cut and the single overloaded, when I needed 40amp supply to my towbar socket but only 20amp wire we fed 2x20amp separately fused feeds, if one gets cut it will overload the other and blow the fuse
