Great fit for my Nightingale by Worker! Single charge last a long time and provides plenty of power for magazine after magazine of darts! Wroom wroom!!!

We ordered this. Charged with a smart charger and used with a volt meter to make sure we didn’t over discharge it. Unfortunately only one cell drained and now the battery won’t charge. Messaged seller and no response.

Works great. 5min flights, they are the weird factory size, fit in both ways. Nicely done.

Very dependable battery. Very good price for the quality.

GNB has been solid for me in the past but one of the cells in one of the batteries died after a few months of moderate use. One still seems to work fine. It happens...

I am accustomed to looking for instructions online. When trying to find the charge rate I was frustrated I could not find the information, nor is it listed on the battery. However the the included pamphlet stated it can be charged at 1-2c with 3c being the maximum, however it will shorten the longevity of the battery.So good battery but minus 1 star due to poor labeling on the battery.

They were running strong and then they were dead.Can no longer hold their voltage under load.I fly 3-4 times a week.Both batts are paper-weights now.Roger

Bought these to get longer flight times with my 3-d trainer. They did exactly that, now almost a full 7 minutes. Been through a few cycles already and holding charges just fine with good power. Might buy some more as they are a great price. 10/10
