Rechargeable Screw Post Lantern Battery

This design allows the maker to create a battery housing compatible with both 6V and 12V large screw top lantern batteries. Mine was specifically designed to work with my Ray-O-Vac metal Sportsman lantern that I have owned since the mid 60's.

I adhered to the dimensions for the original battery found via a web search and it should fit any device using this type of battery.

a 12 volt Li-Ion rechargeable battery pack from eBay (and elsewhere) is used in the pack. For a 6 volt output a DC Buck convertor was used.
