Home made 26650 holders & lipos

[tat32]

Hello

I'm looking for ideas for making a 26650 battery holder, I've made one but I'm not happy with it it's a bit too long.
And can anyone recommend a good lipo supplier and are they ok to wire them parallel, and will the sx350 charger be ok charging them?
Thanks

Hi, why not just take a dremel/file to the sides of an 18650 holder? I heavily modified my keystone one without much problem (for different reasons, but still withstood a good bit of hacking and bashing!). Im assuming it would be possible incorporate some support to the battery with the enclosure you are making.

Try here for lipo's and they work fine in parallel, also the sx350 charger is ok for charging them as long as they're in parallel.

yes I thought about doing that but my mod walls are thin 3mm, it's very strong wood so it might be ok.
But I would prefer it to be a separate holder to hold the battery tight.

26650 Battery Holder - Revision 3 by jonniemac on Shapeways

Bit expensive tho, and requires your own tabs!


Viewing your picture tho....my inner bodger is screaming, file sides down from holder A....glue sides/surround on from holder B!!!

Yes I've seen them
I'll have another go at it tomorrow I thinking about changing the spring to a leaf spring and filing it shorter and joining the wires on the inside.

You can strengthen the wood with thin set cyanoacrylate glue, just keep dripping it on the inside until the wood wont absorb anymore, be aware that it may get a little warm.

I've used this trick plenty of times to harden punky wood. On big pieces requiring lots of glue the glue reaction/heat causes so much heat that the wood starts to smoke, have yet to actually have anything burst into flames, but I keep a bucket of water close at hand.

Good idea but I'm not sure it will work very well with the wood I'm using, I'm using katalox it's very strong but it's oily and has a dense grain so the glue might not soak in.

Your right with a wood that dense. If it's as oily as something like tiger wood or teak, those woods as you my know, can be a PITA to get wood glue to stick to.
