DIY split charge

96terrano · 22-07-2013, 19:40

ok so split charge kits are £40 to £65 ish, so just simply googled DIY split charge and this came up, would this diagram work? i've got a 100amp relay and everything else....or will i need a proper kit? thing is, this diagram looks too low amps

thinking of this for the little Hyundai since i'll be using it for holidays

ahh ok, so charging a battery doesn't pull many amps?

Hi Ryan,

I run the alternator wire to the relay with around a 30 amp fuse both sides, alternator will pump out loads of amps to a flat battery
The thin blue wire on the alternator is the one I use to hold in the relay, on my Mav anyway

My first post was a wrong you saw it before I changed it.

I've used something like one of these in the past. Much simpler and better in my opinon.

Not bad that

It's easy enough to work out without a diagram. Just use relay, fuses and cable thats rated appropriately.

One of the reasons I'll be fitting a split charge to my Troll is because I want to fit a winch at some point, am I right in thinking that the relay will need to be a bit beefier than the one in the eBay link, ie. rated higher than 40A, like a T-Max or X-Charge system?

Should I be looking for slightly higher than the rating of the alternator (iirc 90A) minimum? I'm guessing a winch will likely draw more out the aux battery than that if it's working but surely the most that will go through the relay will be the max output of the alternator?
