Re: Winches and Batteries
The other reason for isolating is also due to the inequality of charge in batteries...two batteries will never have the exact same charge and when wired directly together in parallel, they will try to equalize, but because the transfer of energy isn't 100% efficient, they end up using energy, continously, until one of them dies... The isolation of the two batteries prevents them from killing each other while the jeep is off (as well as providing you an option of preserving one battery in a high-stress situation (winching, etc) to have a backup starter battery in top condition). If you really wanna do it without a isolator, use two 6-volt batteries and wire them in series (credit goes to CJDave for that idea...) but you still won't have the redundancy involved with the dual 12v isolated batteries.
The jeep is up and runnin...damn...work work fix..the jeep is...damn...work work fix...the jee...damn
