Dual batteries

[moe.taco]

Thanks to Chris, Ace and Steve for helpin me finally finish this project a month after I started.

I decided to do this project because i really wanted the ability to self jump start my truck. Also, its kinda nice to have electricity for misc. stuff while camping. I also just wanted a challenge and this was a challenge.

In the process of doing this mod I also ended up upgrading the battery ->starter cable to 2 awg. and the Grounds to 2 awg.

All in all, this was a challenge to figure out the best way for my needs to do this. But, I am happy with the results. Especially the fact that my total voltage drop from the bus bar in the fuse panel to the 2nd battery is only 3/100ths of a volt. Pretty good in my opinion.

Here is my vague parts list:
-2 batteries(interstate, 24 series, 800 ca/1000 cca)
-Napa # St-36 solenoid(200 amp continuous duty)
-2 Napa # AR-272 relays (30 amp SPDT)
-25’ 2 AWG battery cable(red)
-1 box of 2 awg. lugs
-15’ 1 AWG welding cable wi/ lugs
-Clamshell of 14 awg. wire(100’)
-Insulated Female lugs and spilices for 14 awg.
-Marine battery switch(Blue sea 9001c)
-4”weather proof junction box from home depot
-Marine battery box for 24 series battery
-Heat shrink for all size wire and cable being used
-Lots of wire loom
-4 military style battery terminals
-Rubber grommets that fit cable/wire size
-No ox-id paste

Necessary tools and misc.:
Cable cutters
wire stripper/ crimper
good voltmeter
electrical tape
solder
Mapp gas and torch
assorted nuts and bolts
drill
zip ties(of course)
fuse puller
