I Had a rainy day and decided to make a project that I started thinking about a while ago. I have never liked the idea of separate battery box's but I dont want to modify the electrical system in my troop carrier so I think this is a good option.
70AH AGM Deep Cycle Battery, in Fully sealed hard case. 2 Cigg plugs, 2 USB power plugs and Anderson plug. A battery isolator, cuts power to everything.
On the side of the battery are a variety of cables that plug into the Anderson, one with a cigg end, and another with jumper ends for charging the battery and an Anderson - Anderson extender.
I managed to put it all together for a little over $250 AUS.
