URGENEX3.7V Drone Battery 380mAh 25C 1S Lipo Battery Fit for SYMA Holy Stone Drone Quadcopter Aircraft Parts 5PCS RC Battery with 5in1 Charger

These batteries seem high quality and have flown today to test these batteries and 2 was all I wanted to fly anyway. It was almost 20 minutes. When the warbirds first come out I got several of them and it just seems like last month the batteries started going bad and they have been darn good to last that long! Hoping these would be even better for the same would be awesome.

Each battery lasts about 6 to 7 minutes. I’ve only had mine for a few days. I numbered mine to maybe monitor flight time and charging time. As far as delivery. I did decide on a locker delivery. Had an extra almost 23 hour delivery delay. Probably because lockers were full with Christmas presents. Yes I was disappointed but I understand it was and still is a busy time of year. And our delivery drivers need more of of our thanks for what they are doing.

Batts are great… but i fried my lil drones board (ordered and installed a new one from ebay🫤) because I didn’t chk the batts polarity. If you have a question about this just hold your original batt next to it, visible metal in the pins towards you, and make sure red and black match. If not, just use a pin and pop out the little pieces holding the wires in and swap them.✌️

Each one I test for short circuit and capacity.. All have passed the short circuit test (unlike what I've bought on alliexpress). All have exceeded there 380mah rating.. I've had anywhere from 385 to 410 mah. And after use of 1 year. They still test above rating. I'm impressed.

Works great with a older harper mage drone. (Don't know if I say a name brand lol) add some vowels... Well they certainly are worth the money for that because it's a good afternoon just rotating the queue of batteries. Always keep them charging and it can go on for quite a while. 👍 I have it in a good protective case ready to break out and practice some drone skills 🛸 if I ever get some RC cars for the kids I know which types of cars to get them as far as battery type goes. It may limit the selection but they are small and need to learn small haha no need for 30mph vehicles.... Anyway rambling. Seems like a good package with decent enough quality that suits the purpose.

Nice

charger has a charge rate of 1.3c with this batteries

So far when more than one battery is plugged in, the led indicators are flashing, or not lighting at all. I'm assuming the led should be solid when charging? If I am correct, only one battery will charge at a time. Hoping seller or someone can correct me if I'm wrong.
