After my relative success witht he first battery box i decided i would come up with a more flexible option. THUS MORE POWER... lol
If you know anything about batteries and tapping batteries you could see how this would be a good option for a battery supply that can be configured for multiple + and - voltages in the pictures i have configured it to run 3V in parallel for testing leds and running some small coils i have built but if you change the wiring with either the bolts or the bus wire you can change it to be any thing all the way up to a 24V battery pack.
print one lid and one box or if you aneed more power these can be screwed together with all thread to create huge AA powered battery boxes which is handy considering the falling price of NIMH 3000MAH batteries. on ebay you can buy 100 of them for 30$ or if you get the harbor freight coupons you can get 25 AA garbage cells for free. or dollar tree sells 10 AA batteries for 1$ either way you go it is a pretty good option .
