so after taking out my extra batts and system i tried to start my car and i found out that my starter batter just couldn't do it.. (makes me wonder how long its been bad) so i need something to replace it. if i go stinger i think the 800 is the biggest i can get to fit. what is good for a starter battery? is it worth the money to get a dry cell? i knwo they are better but if i am going to have other batteries anyway in the back . i just want to stretch my buck
This is why you should not wire different batteries together non isolated, especially ones of different types. Do that and you'll have this same problem all over again later.
