Have you looked into getting a battery isolator ?

Use this in conjunction with your existing setup. Capacitors will only supplement your power .... not cure your alternator problems. A larger alternator and if you are going with multiple batteries, then an isolator is a very efficient way to go.

It sounds like you need a bigger alternator, not more batteries. If you add more batteries and an isolator, you won't kill your driving battery or your alternator, but it may not charge of if your alternator can't produce enough current. You may wnat to look into getting a high output alternator. It sounds like that would solve all of your problems.

Check out this link it will tell you everything you need to know. But I would not add the second battery until you upgrade your alternator. http://www.eatel.net/~amptech/elecdisc/
