Hi folks,

I’m looking to build a lifepo4 pack for LED strips, and I kind of want to use these 32650 cells from battery hookup. NEW BATTERY HOOKUP LIFEP04 32650 3.2V 6000MAH CELLS – Battery Hookup
At $2.60 for 6000mah, is there any other deal that comes close?

Alas, I have no spot welder, but I do have a 3d printer, so I’m hoping for some kind of NESE-like thing. Has anyone designed something for 32650 / 32700 cells yet? I didn’t want to post on an old thread, but @winfly @shaman maybe one of you has made some progress on this? Another Printable Modular 18650 Battery System - #11 by shaman

One more thing, since it’s meant to drive LEDs, and the 12v strips can’t really handle the 14.4v of a fully-charged 4s lifepo4, I think I’ll need some kind of voltage regulator?
Does anyone use voltage regulators in their packs or know what I should do to bring 14.4 down to a steady 12v? A bit lower voltage would be okay, but the diodes can’t really be driven higher than 12v.

Thanks!
