Wow, these cells are great!
I purchased some of these tabless cells to try on my 1S 3" HD Toothpick drone build, and, albeit a bit heavy for 1S, it flies pretty well. Not a freestyle monster, but an endurance beast with decent send. These cells shrug off the demands of a BETAFPV Matrix HD AIO flight controller/12A ESC and some 1202.5 11000KV motors. I'm getting 15+ minutes of speedy flight time from a single cell trying not to go below 3.2V, and about 20+ minutes cruising. Love these cells and will definitely buy more when time comes, only from DIY500AMP, who are terrific!
