I'm looking to isolate a few car batteries I use for lighting in my garage (I live in an apartment, no power in the garage). So I currently use 3 different brand, different CCA batteries, all 12 volt, connected though a 400 watt power inverter. I usually connected them in parallel with jumper cables, but have come to realize that's not a good idea. I plan to build a connection rig to connect the batteries with much shorter, more secure cabling, and want to include battery isolation via a diode on one of the leads coming from each battery. I want to make this easy to upgrade to allow more batteries if I get more in the future. I feel like this should be an easy task, accomplished with a single diode on each battery. I can easily figure the wiring, it's just short battery grade wires connecting the terminals, no problem there, but the problems are: 1) which terminals should the diodes be connected to, positive or negative? 2) what diodes can I use?
Any help would be greatly appreciated, Thanks!
