Alex,
It actually bothers me that the pomona terminals are $9 in 1QTY and just $1 cheaper in 100QTY.
Another thing that hinders me from considering those is that they are very long, it could annoy people that don't have the perfect LiPo battery to fit between them (input/output), or the box would need to be 1CM deeper and things like that... Also would need to posibly change the terminal holes to fit them right.
Having a separate PCB revision just to make those terminals an option, is not feasible.
