I don't seem to have a pic of the battery finished in it's box, but here are the cells connected into a 12 volt battery, connected to my Powerlab8. The two tabs connected +/- are what stick out of the little box once complete. I made the interconnects out of soft copper tubing hammered flat and drilled. Each one of those little cells will put out about 270 amps, so this light weigh 3P battery would put out about 800 amps. 4P would do over 1000 amps.
It seems rather "interesting" to be discussing lead acid batteries in a thread for "lightweight" batteries. If your handheld phone used lead acid, it would weigh more than you'd like, be much larger larger than you would consider practical and last until first coffee break..... if you were lucky. lol
edit. . . oh I almost forgot, lead acid has a cycle life in the 200 to 500 range. With good LifePo4, you could add a zero to those numbers.

Gary
