My DC-DC Battery Box
Posted: 14 Apr 2015 09:11
So I have been looking at a second battery/dual battery system for a wile now. After posting a question on this forum it seems like at the end of the day a DC-DC system is the way to go. I looked around at my options. I was very tempted to go for the HCDP DC-DC charger sold by Bush Power. Their unit that they sell with a battery is an 12A system and not their 30A unit. Their price however is quite competitive and to courier the box and battery to Bloem would have been only R350. The quote I got for the 12A system and lead crystal battery was R6649, courier included.
The option I went for after deciding to bite the bullet and rather do it right the first time was a CTec D250S Duel charger and a 100Ah AGM battery that I could get in Bloem at Current Automation. The charger and battery was R5724. Not to bad if I look at the other quotes I got.
I bought a battery box from Outdoor Warehouse (OW) and a battery volt indicator with Brad Harrison plugs and some cigarette lighter plugs. All the components can be seen bellow.
On Saturday I took some time and started modifying the the box, wiring and assembly. I used 10A circuit breakers instead of fuses. This is just easier to reset than to replace a fuse and at R35 one it was not that bad an investment.
Here are some photos of the end product.
Unfortunately I had to put all the plugs on the lid. I also had to make the wires to the plugs long enough so that it is not a hassle to open the lid.
My next step is to connect the CTek with the battery in front. It will connect with a BH plug, I will do this tonight or tomorrow night. We are leaving for the Richtersveld in two weeks time. I will properly test it there. The nice thing about the box is I will be able to remove it completely from my car and put the fridge and box in the tent or somewhere closely. It does not have to be in the car that might have to stand in the hot sun.
I will take some photos of the box in the car after the complete installation.
The cost of the box with all the fittings, bolts and wires are R7800.
