Optimal Battery Setup

[blong4life 10+ year member]

Hello Folks,

Long time member first time poster here. Just got a new job, gonna have some money soon so I am gonna build a little system in my escort.

Here is what I am planning on doing. A dual battery setup (main battery for normal electronics upfront) and one in the trunk for the amps. Gonna be using some heavy duty wiring for the setup. Now how would be the better way to do this? Since I have the battery almost right there, just run the +/- from the battery too the amp, or would still grounding to the body be the way to go? Probley won't start building for a few weeks, but I want to get some plans.

Have some more critical things to take care of (like those bald tires before winter comes) and a block heater.

a good ground to the back battery is all you need then you can run it to the amps

Alright that's what I thought.

Run a ground wire the same size as the power wire to the rear batt. Also ground to chassis on both ends.

Ok sounds good; got an almost new duralast sitting around it's double the size of my normal battery though lol.

you dont need a ground wire front to back unless you cant find a good spot out back i have 6 batterys grounded to the frame out back works fine been this way last 3 years without 1 problem

so how is the battery in the back going to get recharged?

you run a power wire from your front batt to the back...alternator charges both

run 0 gauge frm front to rear battery..then from rear to amp...fuse between front and rear battery and then fuse again between rear battery and amp

To the best of my knowledge, unless you run power from the front battery to the back, the back battery will have no method of charging...unless you manually charged it every couple of days

I was actually thinging of building a trickle charger in because I am going to be installing a block heater soon, so it will charge every night; so with the 120v there why not charge the battery too?
