I currently have no onboard charger. I have 2 batteries on a perko style switch with 1 battery going to 1 post and the other going to post 2 with all power draws going to the common post. For the cranking battery, i have a 625 cranking/120 reserve battery and for the audio i have a 900 cranking/205 reserve battery. Which dual bank battery charger would be the best/most economical?
Thanks!
