elmscroft Posted September 8, 2009 Share Posted September 8, 2009 Hi All, I have an M8000 fitted on my 90 with two batteries going under the passenger seat. Someone on the forum had mention using a fork lift truck relay to charge the second battery. Does anyone know which relay it is or any other info. Thanks Mike Quote Link to comment Share on other sites More sharing options...
western Posted September 8, 2009 Share Posted September 8, 2009 mine are charged using the standard LR spilt charge relay system. AMR3324 or the X-charge unit Quote Link to comment Share on other sites More sharing options...
petethepilot Posted September 8, 2009 Share Posted September 8, 2009 mine are charged using the standard LR spilt charge relay system. AMR3324 or the X-charge unit Mine has a standard camper charging relay, cheaply from car parts store, takes 60 or 80 Amps, works just fine. About 15-20£?

Thanks Mike Why waste a battery on just starting the car, all the running load usually comes from the alternator (with winches being the exception as they will draw more than the alternator will supply). You only need starting capability if you are very good at stalling it and then you won't need a fully charged battery. I would just run the two batteries in Parallel, I think split charge systems are good if your second battery is a leisure type battery for running things like fridges. They are not useful for running Winches, especially when you are running a 100Amp alternator (I think that you could melt a split charge relay that is not rated to your alternator output with a winch).

western Posted September 9, 2009 Share Posted September 9, 2009 hasn't done any damage to my 100amp alt or split charge relay. Quote Link to comment Share on other sites More sharing options...
TheBeastie Posted September 11, 2009 Share Posted September 11, 2009 Not sure if I am missing the point but I put in an X-charge so that I can run radio (and inverter) off second battery without fear of having insufficient charge left in main battery to get started again. If straightforward parallel then lots of amp-hours certainly but you can still run the whole thing out out of juice without necessarily realising. The split charge gives you that additional security which I reckon is well worth it. Quote Link to comment Share on other sites More sharing options...
rallycinq Posted September 17, 2009 Share Posted September 17, 2009 I have a split charge relay ready, the original battery in my 110 CSW is quite big. What is the perceived wisdom on location and or size of second battery. I want to run the inverter, possibly beacons and radios from it.

TheBeastie Posted September 17, 2009 Share Posted September 17, 2009 I have two fairly standard batteries squeezed into the box under the passenger seat. Feed and supplementary fuse box from 2nd battery on rear bulkhead. Works for me. If radio transceiver remember to fuse both +ve and -ve supplies.

western Posted September 17, 2009 Share Posted September 17, 2009 2 big odyssey 1700 in my battery box, one runs the winch & other does everything else, no problems so far. Quote Link to comment Share on other sites More sharing options...

The 'standard' battery in my 110CSW doesn't leave a lot of room for a second decent sized one. Maybe need to look for two batteries.

FridgeFreezer Posted September 28, 2009 Share Posted September 28, 2009 I have two slim Hawker batteries in the boot, they fit within the overhang of the roll of the body so don't lose any space, especially as the spare wheel is stood up in front of them.

mmgemini Posted September 29, 2009 Share Posted September 29, 2009 I know two Odysseys will fit in the standard Land Rover battery box. I've seen it done. You will need a bas board to level things out. As I consider the price oof that type of battery out of my price range. I modified my battery box to take an large Numax boat battery in there. Modifying the battery box meant I could fit two fuse boxes and carry the jump leads in there as well. I use a standard Lucas split charge relay. mike Quote Link to comment Share on other sites More sharing options...
