Second Battery

(1/2) > >>

JimP:
OK I'm going to be fitted a second battery as I've now got a winch and lots of lights!

So how do I wire it up?? just wire it inline to the existing battery?? +ve to +ve and -ve to -ve?? or do I need some sort of split charger or something??

Cheers

Jim

PITBULL:
mine wired inline its fine i dont see a need for split charge but thats my opinion

Disco Matt:
I'd go for a split charge system, they really aren't that hard to sort out. You just need a 30a relay and a live feed switched when the engine is running/alternator is turning. That way you can have auxiliary systems connected to the second battery (eg CB, computer, etc) and don't need to worry about those flattening your main battery when the engine is off.

ChrisW70:
Split charge system would be best if you intend to run equipment for long periods of time without the engine running, a deep cycle battery would also be best.
Normal occasional use of winch and lights at night you'd be better to run a normal battery connected in parallel with the existing, if you're concerned about running the battery flat you could always connect all the ancillaries to the second battery and an isolator switch between the two.

Do not connect your batteries in parrallel. This will make your system 24v which would be very bad!!

As you say, connect them in series. +ve to +ve and earth the second battery to the chassis rail below the auxiliary battery tray.
