3.7V 140mAh 242530 Lipo Battery Rechargeable Lithium Polymer ion Battery Pack with JST Connector

Bought a couple of these for a micro quadcopter, figuring that since it was listed as "high discharge" and that it listed "mini helicopter" in the list of appropriate uses that It might work out. Got it installed in the quad, charged, and it flew for about 15 seconds before the low voltage circuit kicked in. Checked the voltage and it was 4.12 with the motors not running. It dropped almost instantly to 3.25 volts when the motors were just started. I took the battery back out, hooked it up to my lab equipment, topped it off and attempted to discharge at 400 mA (5C), however that was too much. backed it off to 80mA and it seemed ok.... So this is NOT EVEN CLOSE to a "high discharge" battery! This is more of a .5C to 1C discharge rate type battery and totally wrong for any kind of application like a micro quad or other R/C vehicle, even though it is listed as such. Buyer Beware!

It is impossible to evaluate a battery one week after purchase and installation. It was the correct physical size and capacity for my application. So far, it is holding charge longer than the five year old battery it replaced.

If you looking for a lipo battery for your Adafruit Feather you may fry it because it uses different polarization on JST PH 2.0 connector. It seems like RC and Arduino hobby use different standards.

Hope to get it seated into place in my mp4 players. Had to wait a longer time than I’d hoped. Similar to the old one so who knows?!

GOOD WORKING BATTERY! I thought the first battery I purchases was bad, but it was a failed 2KAX lithium charging IC CHIP that was the problem.

I replaced the battery in my electric skateboard remote. its bigger but fit good and the plug adapter fit perfectly also. no solder.

Phew, it wasn't a dud! Will buy again from this seller.Update: Barely two years later, it's a dud

The battery was a replacement for my old battery to my Bluetooth Speaker, I found out after a full night of charging, it would only last with continuous use about 4hrs but if I turned the Bluetooth Speaker high Volume it will only last about 2 hrs. Not Happy!!!
