One of the best PH2.0 1S lipos that is readily available

Super power for the short bursts I need

Got these for my brushed whoops from NBD. They work great with those and the hummingbird brushless. What they don't work good with is the new AcroBee V4 Crossfire! Taking them down to 3.2 made them very warm. Then the second flight (down to 3.2v ) made them puff. All of my 1S have 3.35v warning and 3.2v land now ....Not sure why AcroBee V4 Crossfire is like this. They seem to like anything else but the new AcroBee V4 Crossfire!??!

Have been using (abusing) these for 2 years off and on. I prefer the 300mah for a little longer flight time, but the 250s are slightly lighter and cheaper and work just as well though shorter flight time. I beat these up preetty hard by draining them below what is usually advised, and sometimes leaving charged for longer than advised, but hey still work well enough for casual use. seem to hold up better physically and electrically than the cheap GNB, Gaoneng, and happy model 1s batteries I also have.

Got these because they're as good as the 300mah Niyro Nectars but they weigh a little less. Indoor acro is that much more rewarding with these little whipper snappers in your battery bay. Know what I'm sayin'?
