Leisure battery via alternator

furyash

Hi. I have just joined the world of campervaning and so far I am loving it :) I have always wiled camped with my tent, and this is just an extension of my wild camping fun.

My van is a SWB Iveco Daily 29l9, with lights throughout, a heatsource 1600 and an electric hook up with two power sockets. The trouble is that everything is powered off the vans battery, so when we are parked up, with the lights and music on, I always worry about draining the battery, and once it gets to winter I am going to need the lights and heater on a lot more (I live in Scotland).

I have been reading up on leisure battery's all over the net, but I am finding it all very confusing. I only wild camp, so use of the EHU whilst away wouldn't really be an option, and solar panels in Scotland in the winter?!?!? So I am thinking of charging from the vans battery or alternator, I realise this has mixed reviews, but for me I think that is the best solution.

Now the next problem is that I am a complete ape when it comes to anything electrical, and struggle to understand any of it! Pictures are best. Could anyone suggest any links/point me in the right direction of what needs to be done (listed in detail), as well as all the parts (what cables, split chargers ect) I need please? Or could anyone here tell me what I need to do and buy?

Thanks very much for any help, I feel like a rabbit in the headlights right now!

Various ways of doing this...simplest, battery cable from starter battery to Aux battery, earth Aux battery securely, and a heavy Duty cut off switch in between....or a high amp relay which triggers when the alternator kicks in and off when the engine isn't running or various smart relays from around £30 up to £200...it's all down to taste and budget...

Just google it and you will find plenty of diagrams online...
