EEMBLithium Polymer Battery 3.7V 250mAh 502030 Lipo Rechargeable Battery Pack with Wire JST 2.0mm Connector for VXI Blue Parrott- Confirm Device & Connector Polarity Before Purchase

Just as advertised! Little did I know the connector would be too large for the SkyRC GPS unit! So I had to alter it. It has 0.02mAh larger capacity than the stock battery, but squeezed in nicely after I changed the connector to the right size.The battery arrived @ 3.63V, and charged up nicely.

I got this for a dash cam. My dash cam had 3 wires, one of which I am sure is just for the battery management. This battery only had two wires which is not unusual.I just connected those two wires with solder and left the 3rd wire off. I would like to make a disclaimer that I am not an electrical expert nor am I suggesting anyone do what I did. But my camera works now.

Met all the requirements to replace a 2017 vintage battery of the same type! Works excellent, charges and holds charge. Gave extended life to this old device!

Did not last very long, I thought it would give me at least a year for lithium battery, but the thing crapped out in like a month or two.

The light uses a 602030, but couldn't find one made by EEMB in that size. I'm hoping this, supposedly certified battery from EEMB, works better than the original and a cheapy replacement that I paid about $5 for on ebay. Neither one lasted very long. This 502030 250mAh battery ran for 13 plus hours on low mode. For anyone wanting to replace their MecArmy SGN3 battery, here's how to do it. I'll try and get back with an update in 6 months or so.The battery number(602030) is on the battery. To take it apart 1. Remove rubber on/off button cover, it comes out from the top 2. Pull out micro usb cover and don't try to remove it completely as that can't be done until the inner circuit board and battery are removed. 3. Use a utility blade to work the front section away from the main body, while making sure the micro usb port doesn't get hung up on the cutout of main body 4. Slowly work out the front section and battery. Do not pull the battery out by pulling on the wires that go to the circuit board. That's it. Just be careful when putting in a new battery as you don't want to short it out. I used heat-shrink insulation tubing to cover my connections. Solder/insulate 1 wire at a time to prevent a short. Don't mess with the battery or circuit board wire connection points. Cut in between at some point and solder the connections. Hope this helps.

Buy the reverse polarity because it's 1 dollar cheaper and you're gonna cut off the connector anyways.Youtube tutorial on battery replacement on this 8 dollar battery is much easier than buying a new dashcam for 100 bucks. Absolutely perfect and holds charge like brand new.

Replaced small drone battery in kind with same voltage and amp rating. This replacement funs for less than a few minutes before discharging. Old one was good for 15 minutes.

I used this to replace the rather short-lived native battery in my Auvipal wireless remote. That was a 200mAh, 3.7-volt battery slightly thicker than this higher-amperage battery. The remote was not hard to crack open, and soldering in this replacement battery was quite straightforward. Because of its higher current, it performs better than the original.
