Of the 12 lipos I received, 4 of them failed on first run (one didn't finish its first charge, puffed and hot). The response from NewBeeDrone saying these lipos are "hit or miss" and to have a nice day, is unacceptable. Any products being sold with a 33% failure rate, and the seller to know their inventory is old stock, or, "hit and miss" should have a disclaimer. Now, of the 100s of GNB 1S lipos I've had, never has there been so many bad ones. If all I'm going to get is a sorry, have a nice day, I won't be back for more.

Very good perfomance.

I like the added mAh over the standard 300mAh HV cells. It gives a little extra flight time for essentially zero added weight. Great for zipping around my house with the Mobula 6.

I’ve flown and recharged these batteries maybe 5 or 10 times each now. Out of the box they feel pretty good, but I have been noticing some lack of power and duration compared to the nitro nectar batteries after flying them a bit. Sure they are a lot cheaper, but their higher burst rate and capacity seemed to wear off after a few flights. Maybe I got a bad batch?

Good batteries have around 200 cycles on each and ir is still about the same. Alot better than the 30c version noticeably less sag at hover
