Super Deluxe Turbo GTI Cox Battery Box !!!

Ken Cook wrote:Woody, I mentioned this on here some years back. One of my flying buddies made something very similar to what you built there. His starter battery had 4 D cells.   On the ride home one evening , something shorted across the jack outlets and it ended up catching fire. Not only did it do extensive damage to the car, it also burned his hand seriously. Seeing how you have both terminals exposing metal on the top of your box reminded me exactly what he had. From that point on, I use a fusible link for all of my starter batteries.

Crickey Ken!
Thanks for pointing that out!
I was quite chuffed with it till you wrote that!
I am very grateful for your advice.
I will do something about it.
Okay ....My description was a lie .

Quite the contrary -- your box looks great!  Here's a couple of options to consider that have recessed metal parts:

Digikey - Keystone Electronics

Digikey - Cinch Connectivity

Red shown, but black is available as are different tab types. Where I live, this type of inventory is non-existent, but these jacks, as you well know, may be found all over the interweb.

Another option would be to install a 5-10A fuse to the circuit. There's plenty of room inside the box for an inline fuse holder. Might be good to sacrifice one or two fuses to see that it won't blow when you use it, but on the other hand, blows when shorted.

Nice setup by the way

It's a good idea but to avoid a short circuit having something on the batteries Because the only thing that protects the negative from the batteries is the little plastic envelope on it If it moves it could come into contact with the positive terminal possibly I should make myself a new pack mine is very used

I am not sure what you mead David?

What I want to explain is that now the batteries have an envelope made of metal And that the negative terminal is on the whole surface
And if the pack moves inside it could come into contact with the positive terminal with the negative on the outside and only the plastic film with the name number of c and voltage which protects from a short circuit I prefer to use a small pack that can be inserted into the sleeve of a long-sleeved vest Over time I learned that the glow plug clip tends to be short-circuited So I got a little piece of foam That I put on the end
Ok it's very ugly but functional space-saving never forget behind never short circuit

Hi David, steel case of a battery is positive, not negative.

Depends on the type of battery!!

Alkaline battery:

Very good point David! I didn’t think of that.

Conventional batteries are less dangerous compared to the new lithium ion which is manufactured in a very similar way to nicd But with much more power to ignite wires or cause serious injury And frankly often the plastic wrapping around it is very thin, easy to puncture or tear And yes it is possible to have one or the other with positive or negative expose inside the battery envelope It depends on the manufacturer I remember a particularly strong battery model the pannasonic evolta was my favorite now impossible to find It was the cheapest and yet the best battery that I had ever used. It's always the same thing when I find something super good it becomes impossible to find One of the only thing that remains that I can have new without problem a good old COX engine is for one of these reasons that I like this brand

Thanks David for explaining that.
The battery holders cannot move as they are glued to the base of the grey box housing.
The terminals can be swapped over for insulated ones.
The whole was intended to be as simple as possible yet sturdy and the batteries easily replaced.
I will just be careful in the interim.
Woody.
