What a surprise, another dual cell mod question

[midget_man1387]

I'm not sure if anyone has asked/done this(If they have, feel free to delete this post, but please give a link first), but, is there a way to do a dual cell mod using two NiCd batteries without soldering? Because I want to do one, but I can't solder(my dad can, but I don't want him to). I also plan on making a charger too, but I'd like to first build the dual cell.... Thanks for your help, guys!
