11.1 Volt Battery pack
Description
This Is A Battery Box That I Designed And Made For 3.7 Volt Batteries. It Has A Cover And I Am Using 2-56 Size Machine Screws To Attach The Lid. The Small Square Holes Mark The Place To Drill For The Screws. I Used Copper Sheet And Snips To Create Tabs For The Battery Contacts. I Folded The Copper Into Two Layers And It Fits Snugly In The Slot With A Tab Coming Through The Recess And Making Contact With The Batteries.
