Trying to go solderless?...sure, I've seen guys that have used the automotive style bayonet connectors in their
mods with good results, they just take up a fair amount of space, and the connection, seeing as it's "friction fit" can be prone to V drop if it gets loose so if you're a sub ohmer, a certain amount of maintenance will be required.
Though listen to me talk about taking up space...a lot of modders have gone to PTC fuses (they trip when the current goes above their rated value, once the fault is cleared and they cool down, they fix themselves)...they're a great idea, work well and take up very little space but if I have the space I use one of these:

You can find them at almost any Pepboy's/NAPA/O'Reilly's...and get a supply of 10A fuses (if you deep sub ohm, go with 15A) and you're good to go...and again, you can put it in your pos. or neg. connection.
