6v Lantern Battery adapter

6v Lantern Battery adapter

Postby bbrown64 » 2015-Sep-Mon-07-Sep

I have a idea in my head to redesign those big square 6v lantern battery adapters. I know the existing adapters use 4 D cell batteries. My idea is use 2 18650 batteries instead. The benefits are a weight reduction from 144g down to 45.5g or less. I want to be able to replace batteries should one go bad. My question is there anyone willing to collaborate with me in design and building of this proto type?

I'm not quite sure exactly what you are aiming at.

Do you want to create a brick that replaces a 6V lantern battery, which could be used in its place? (That's my first guess, based on your info about batteries used "internally"). 6V lantern batteries have springs for the terminals - do you have a source for those springs?

Or do you want to create a holder for a standard 6V lantern battery, so you can power up devices of your own choosing?

Jay, Your assumption is correct. Yes I do have a source for the springs on top of the adapter. I simply want the weight reduction and a better battery than 4 D cells. I thought about buying a 4 D cell adapter and take it apart and modify it. Then come back and make a 3D print of the modifications. That would be a proto type.
