Hi Brew69,
While a deep cycle will have limited capacity to accept a charge, it will still readily supply heaps of amps when starting if you forget to switch it off. Also, you (or the next owner!!!) may change the
battery type in the future, forgetting about this limitation.
There are many budget ways of isolating a 2nd
battery. One way (NOT the only way) to do it, is simply wire the two
battery +ve terminals together using proper (thick)
battery cable with a fusible link. But, use a manual isolation terminal lug on the
battery, these are cheap as chips.
This way, you can easily isolate your
battery with a relatively "high amp" switch. Also, if you do leave it switched on when starting the vehicle, it can handle the high amps. Plus, you can change the type of batery without worrying about the type of isolation system you have used.
This is only one of many budget solutions. I'm sure many will post of other solutions too.
Cheers
Captain
