Rainy Day Battery Project.

Unread post by Rogers Cruiser » January 11th, 2016, 10:41 pm

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.

Now that is a cool little project. Any chance you could give us some more specifications like parts used etc?

Thanks

Its a large pelican box with a 70AH golfcart battery (brand new)

It took a while to find a thin enough battery for any of the reasonable sized box's.

The positive power runs straight to the isolator, and the Anderson runs from the isolator along with power to the 4pole fuse box. The voltmeter, USB, and cigg plugs come from the fusebox so everything is fused. There is a common ground which is attached out of the way of any positive power.

Looks great. Wouldn't want to leave it at a bus stop or something though! All those wires and dials... :)

How hot does a fairly flat 70 ah AGM get when recharging? Probably not too hot off the car hopefully, but I wouldn't like to plug it into a 25a charger without some airflow.
We make these things up on a smaller scale (7 ah batteries) for our fishing kayaks to run sounders and pumps - batteries come out of the box for recharge though.
Nice job.

I am running it on recharge now (after running a light all night)

Its not getting hot at all, but thats charging from 240V. I will have to run a test with it recharging in the car. It shouldnt get too hot.

Heres an update.

I went camping last week and the unit did really well. Had a large engle fridge frezer that was running of my troppy most of the time but left it running of the battery box for a few hours each day. It also ran the camp lights for 3 nights and charged phones and cameras.

I have decided to keep a few more cables in the leftover space in the box, so I will keep my phone cable, and an anderson extension lead in there from now.
