4s6p battery holder

(Gwa Gwa) #21

I have been working on a similar project. PCBs are on the way.


I have a 3d printed canister that they fit in that uses M3 screws to hold it all together.
These are the springs I am using: https://www.mouser.co.za/ProductDetail/Keystone-Electronics/211-D?qs=%2Fha2pyFadui9q4JttDHta7ui%2B%2FLDVmbiwU8jRQ1OBRE=

looks pretty much the same as mine.

PCBs are also being printed. Let me know how it works :slight_smile:

Would it be possible to sleeve two cells inline and eliminate contact pins in middle? With spring contacts on ends this would be very economical.

Vibration and contact is the bulk of the problem. This is why the springs are necessary.

I am getting sample pogo pins to make some tests, would need to order 5000 for it to be economical…

Ok so with the expensive price of the pogo pins and the machining of all the parts. I can sell this harness for about 500USD.

Not sure if anyone will be interested at that price but I will make a couple for myself…
