I dont wanna Frack anything up tbh.  I was told this by numerous people .. and maybe this is for my set up.  Here it is.  I have 4 batteries.  2 wired in at normal 12 volt.  1 for electronics.  1 for cranking.  2 are jumped for 24 volt only for TM straight 24.  Not 12/24 like i used to have.  It is straight 24.  I have a 4 bank charger on the boat.  All batteries are hooked up to it.  I believe they told me so it wouldn't fry the 4 bank,.. i d k.  Ill call and ask tomorrow why it was stated for me to just unplug it while i charge them. 

Thanks for clarification.  I dont need a 110 dollar bill lol
