Hmm...where do you get your laptop batteries or suggest getting them?I have yet to use them in a flight pack, simply because they take so long to charge, but I use them all the time to power my FPV goggles (the HK DIY ones), ground stations, flash lights, and even as a ground / build test pack. I use battery holders (in 1, 2, 3, 4 cell sizes) similar to these soldered up for series or parallel depending on what I'm using them for. I harvest my 18650 cells from old laptop batteries and was lucky the organization I work for was moving buildings and was getting rid of old hardware. I have a mix of Sanyo, Samsung, Panasonic and Sony batteries from a mix of Dell and Thinkpad laptops with one from an old Apple pack.
Here's an example of the cases I buy (not from this store, but they had a convenient hit from google):

Where do you recommend I get my laptop batteries from?I got my sanyos from a newer Dell XPS laptop battery from a recycle bin. Had one dead cell out of 8. Free and cheep. I run samsung 25r's in my Vape. 25a on those.
