The new Lithium F16 has a way of using the battery compartment as a holder and on/off switch. I liked the idea as it saves any chance of loosing the battery and always has the battery ready to go.
Looked at my now resurrected IM65 and saw a way of altering it to hold the battery in the same way as the Lithium. Won't go into detail as the video shows the simple idea and explains the pros and cons.
