disco_al Posted August 22, 2008 Share Posted August 22, 2008 Apologies if this is in the wrong section to start I was just looking at split charge systems, and was wondering what size relay is best for running with a 70 a/hr battery. It's not for running anything major, couple of aux sockets in the back for charging lamps, and maybe a small size work lamp or two. Any advice from the guru's most welcome Quote Link to comment Share on other sites More sharing options...
LandyManLuke Posted August 22, 2008 Share Posted August 22, 2008 The size of the battery doesn't matter that much, the alternator output current certainly does, as does the load(s) you will place on the system. Which split charging systems where you looking at? Quote Link to comment Share on other sites More sharing options...
disco_al Posted August 22, 2008 Author Share Posted August 22, 2008 mainly the T-max system, and a couple on good ole flea bay. was thinking of talking to the auto electricians in town and getting them to organise the correct relay, then sorting the wiring from there (got plenty of good sized cable about to use) and using a couple of dial gauges for monitoring. it's to fit a standard 90 disco 3.5 (non air con), so i would imagine a 70-80 amp alternator load wise would be max of 55w work lamp, and a charger for laptop/led torch. not planning on fridges and stuff like that Quote Link to comment Share on other sites More sharing options...
Mark Posted August 22, 2008 Share Posted August 22, 2008 A 70A relay would be fine I would have thought, and is pretty much the biggest you can get easily. Quote Link to comment Share on other sites More sharing options...
steve_d Posted August 22, 2008 Share Posted August 22, 2008 .........load wise would be max of 55w work lamp, and a charger for laptop/led torch. not planning on fridges and stuff like that If that is all you're going to run off it why do you think you need another battery? If you felt the need you could up the size of your existing battery but I would have thought your standard battery would have been able to cope on its own.

ozzie1989 Posted August 22, 2008 Share Posted August 22, 2008 I can also recommend the X-Eng Split Charge - it will be more than adequate for your needs. Quote Link to comment Share on other sites More sharing options...
Mo Murphy Posted August 22, 2008 Share Posted August 22, 2008 Another vote for the X-eng split charge system here. Mo Quote Link to comment Share on other sites More sharing options...
disco_al Posted August 23, 2008 Author Share Posted August 23, 2008 If that is all you're going to run off it why do you think you need another battery? I have been given a 70 a/hr battery that will be left to go dead other wise, and as i tend to be out and about fixing cars and farm stuff in the evenings, as well as bail loading/unloading it makes sense for me to add a second battery to run the lights off, rather than end up in the middle of a field with a flat battery. I will probably be adding a light bar across the front at some point too, and will more than likely use the second battery to power that, via a separate feed, so that it can be run independantly of the main lights, for extra front end lighting.

Roverdrive Posted August 23, 2008 Share Posted August 23, 2008 My Vote for x-eng as well. Got Si's system for the split charge on my RRC. Quote Link to comment Share on other sites More sharing options...
disco_al Posted August 26, 2008 Author Share Posted August 26, 2008 Judging from the repsonses the X-Charge is the way to go - so i've just ordered one Thanks for the help and avice all - much appreciated Quote Link to comment Share on other sites More sharing options...
zim Posted August 27, 2008 Share Posted August 27, 2008 i'm not sure on the pricing from X engineering, but you could always just buy a relay such as : http://www.caraudiodirect.co.uk/value-spli...0bca8cc7fafee92 and wire up your own.

ozzie1989 Posted August 27, 2008 Share Posted August 27, 2008 Agreed, you could make up your own kit. I found a relay the same as the one in the kit for a tenner brand new, but buy the time you buy wiring, and the tools to crimp connections properly the x-charge kit works out just as cheap Quote Link to comment Share on other sites More sharing options...
