💡 Why does a handy dedicated fixture beat holding cells by hand when building lithium packs safely?
Tacking down the cylinder lets the pulse shoot straight without frying your knuckles or missing the sweet spot.
- Tight mechanical seating locks the cell so the electrode stays planted dead center through the whole burn
- Electrically isolated handles keep the circuit contained while you manage the power cord and trigger switch
- Predictable gap width ensures even current flow which stops weak spots before they ruin the pack performance
- Snug bench profile clears room for wire cutters and extra nickel tape right next to the action zone
