Fused Battery Holders
#1
I guess the price would probably be prohibitive, but has anyone ever come across parallel battery holders, with replaceable fuses on each cell?

No, but it would be pretty easy to construct.  I've joined multiple cell holders together to create a large parallel charging cradle, just add fuses on the branches and you're set.

Wouldn't that fuse the battery set, and not individual cells.

It's just a visual example of a parallel cradle... which isn't fused at all.

I did say branches, not mains, but I should have clarified further.  Place a fuse between the main bus and the cell holders positive would accomplish what you want to do.

That said, depending on the reason, I may opt against it all together.

I just put a small wire between the neg buss and the holder saved my butt a bunch of times.
this is my low voltage parallel charging rig so it isn't a permanent battery placeholder.
Wow it looks filthy guess I use it a lot. Smile

Dragonfly,

If there were such a thing.... what type of fuses would you be interested in? Something like mini blade automotive fuses or something? 1 fuse per cell or 1 fuse per entire parallel holder? I assume you do not want to deal with solder correct?

I'd be looking at one fuse per cell, and ideally something that can be visually. checked without dismantling or opening. See some decent inline fuse holders but most have covers etc. I want to be able to scan the line of fuses looking for any obvious issues. I don't mind soldered at the manufacturing stage, but when it comes to cell\fuse replacement. I'd rather have a no solder solution.

Sorry still getting to grips with the terminology.

I may tinker with this....literally in tinkercad lol

I am at the phase in my testing where I will start attaching fast-blow glass fuses to my own modules. I am going to solder my fuses in. I will take the opportunity to see if there is a way I can use those in a non-solder format while I am messing around with them.

I do not think it is the way I would like to go. But, I like the idea, and I can see where some people would want to use a system like that. That is what is fun about this forum. Everyone likes to do things differently and everyone has different ideas.

Wonder if you could simply bend the leads on fast-blow glass fuses into a U shape, then use these connectors to hold them in place and complete the circuit? Like use these spring connectors as homemade fuse sockets.

From a charging / testing standpoint… I don’t really see the point of fusing this thing.

Very rarely if ever I think of fusing individual cells, a complete battery yes, but individual cells not so much.

I know Tesla does it because they don’t have a CID in their cell from what I understand, but industry wide, it’s a rare practice which has really appeared to catch on in full effect around here.

You can of course do what you like, but I question the cost and complexity of the process in this thread.
