directly on the cell for lowest resistance
If you can do it in under 4 seconds, I'd recommend direct to the cell. if it takes more than 4 seconds to get a really pretty solder joint, use a bar too. The difference in resistance is so small you can ignore it...think thoudandths of a percent. It's better to be safe than sorry. Good packs aren't cheap. I've detailed the resistances of connectors and wire elsewhere
. Suffice it to say that when soldered well, connectors are as good or better than the same length of wire.
