Configure-able Battery Box

thingiverse

After my initial success with the first battery box, I decided to create a more versatile design. THAT MEANS MORE POWER... haha! If you're familiar with batteries and tapping them, you'll see how this setup can be ideal for a battery supply that can be configured for multiple + and - voltages. In the pictures, I've set it up to run 3V in parallel for testing LEDs and powering small coils I've built, but by changing the wiring with either bolts or bus wire, you can configure it to suit any voltage requirement, all the way up to a 24V battery pack. You can print one lid and one box, or if you need more power, these components can be screwed together with all-thread to create massive AA-powered battery boxes. This is particularly useful given the decreasing cost of NIMH 3000MAH batteries. On eBay, you can buy 100 of them for $30, or if you clip harbor freight coupons, you can get 25 AA "garbage" cells for free. Alternatively, dollar tree sells 10 AA batteries for just $1. Either way, this is a pretty good option.
