As I'm a newbie I have been buying stuff to see how it 'works'
I bought these caps
"
100pcs/lot 21700 lithium battery can be spot welded positive flat cap 20700 lithium battery pole piece DIY assembly parts
"
Basically because I couldn't see how they work from the net listing and then seller didn't reply to my query and I was bored during a lockdown due to .cn virus !!!
My original design was invert the caps. thread a fuse wire and then drop a pool of hot solder into the cap to 'capture' the fuse wire after they are arranged in a pack 'formation' before attaching to the cells. This would mean the cells are not exposed to the heat of the soldering
As my 2170s are genuine Mr Musk has already added a cap on the POS end, so I'm wondering how I could add a 2nd cap ?
- Do I shot weld ?
- Do I wrap ?
- Do I glue ?
...
Anyone using these caps ?
TIA
