Adding a Second Battery, Battery Isolator Question
Hi all, been lurking a long time, but just now decided to post with this question. I've seen similar systems, but have never seen the exact answer to my question. [I did search around.]
I'm wanting to add a second battery to my truck in a custom built battery box in the bed of the truck under the tonneau cover. I guess my questions are as follows;
What is the best battery isolator for the price, on the market right now? I've seen a few reviews, but I'm curious if anyone has any personal opinions?
Because Battery#1 and Battery#2 will be located apart from each other, [Battery#1 will be under the hood, Battery #2 will be in the truck bed.] what gauge of wire do I need to connect the two if the distance from battery to battery is less than 10 feet?
Do I need an inline fuse between each component? As an example, the = is an inline fuse. Do I need; Battery1=Isolator=Battery2? [I WILL be using an inline fuse from Battery2=Power Inverter.]
Any advice on this subject is always greatly appreciated!
[I should note, I'm not using this for stereo or sound equipment, so I don't think that a cap-bank will work for me, and doesn't seem necessary.]
