doing some research on split charging systems:
why?
1) My LWB landcrusier 90 FX only has one battery, and only has wiring for one battery. even though it has aircon etc, but no rear heater or heated seats etc. So i have space for a 2nd battery in the engine compartment. just need to fit a base-plate and fab-up some battery hold-down brackets.
2) I will be shortly be fitting a winch, and a 500w inverter, so would be good to have extra juice for the winch, and also be able to run the 2nd battery to the inverter etc
3) mines an auto, so would be good to have second battery as backup if the primary fails or is flat
Two options I see are:
1) get this kit or DIY similar: http://www.rawcomponents.co.uk/intellig ... 120a-model (£100)
2) get an IBS system like Chris has/had in lil blue. But these are now £178 e.g. tbruk.... even with a 10% discount, a big outlay
Big question is: if you have a winch wired to the main battery, and operating the winch with the engine running, how do these two systems cope. I suspect with the current draw on a winch, the "rawcomponents" (option 1 above) might fail - blow the 80A fuse? as the winch would end up trying to pull current from both batteries, as the relay would be live with the engine running.
And how does the 200A solenoid on the IBS system cope with the winch drawing power ?
