How to weld the battery pack better
Spot Welding Vs Soldering Lithium Cells
It''s always better to spot-weld lithium cells vs soldering them. Spot welding is easier to learn because the type of soldering required to solder battery cells is advanced. If done really well, a soldered connection can be electrically stronger than a welded connection, but it comes at the cost of lost capacity.
batteries
This ensures that the welding current flow is very localized at the "head" or "foot" of the battery, only through the tab and the relevant battery terminal cap The welding current does NOT pass "through" the battery at all, from one battery electrode to the other, but ONLY along the very short, closely-spaced spot-weld/solder tab.
