[Elecraft] Premade tab welded battery packs

[David Christ]

Art sees the same thing I do.  Take those 10 springs, uncoil them and fasten end to end.  That surprisingly long, hight loss length of wire is what all the current has to pass through.  Far from ideal for keeping the voltage and efficiency up.

I have seen better designs incorporated into equipment but never in the secondary market.
