split charge musings by a muppet

Being somewhat of an idiot and a cheapskate too,I was wondering if a towsure voltage sensing split charge box could be butchered to combine a large HD relay.....so as to provide good heavy power flow to second battery but to hold off on the charge switch over until the starter battery is at max capacity...?

....or am I going about this backwards?

....or am I.as I suspect,(and am often told),....a muppet???

look in the Q's and A's section - theres a fred on split charge systems, includingg the system you mention.

a 100A relay and some heavy duty cable will set you back a bout 15 squids. all the info you'll need about wiring is in the Common questions section

Thanks guys.I know how to do the usual low power split charge with the voltage sensing cheapy box,and also how to do a heavy duty system with a 100A plus relay,I was just wondering how to combine the voltage sensing and the 100A relay on the cheap,cos as I understand the regular HD sys will switch as soon as the car is started,not waiting until the starter batt is back to full wack.....
....but as I said "idiot" and "muppet"....I will just have to look thru the Q&A harder to find the cheapo combo method....

thanks for the instant comeback,oh my bruvvers
