EEMB 3.7V Lipo Battery 1100mAh 603449 3.7V Lithium Polymer Battery Rechargeable with Wire JST 2.0mm Connector for Speaker and Dashcam - Confirm Device & Connector Polarity Before Purchase

I used this in a ultra-light flashlight I designed for my drone. I picked up some tiny single cell charger boards with built in low voltage cut-off to make a tiny battery pack. Worked like a champ!

I swapped this battery in place of the OEM unit and I’m genuinely impressed — it works well, and it stays charged significantly longer than what I had before. The build feels solid, the voltage holds steady, and it gives me peace of mind that I won’t be scrambling for a recharge mid-use. If you’re looking for a dependable replacement that punches above its pricing tier, this one’s a great pick.

I used this to replace a battery in my Sony Dualshock 3 controller for my PS3. I needed a battery and didnt want the standard size official Sony battery as theyre very small, in the order of 500 mAh or so. I installed this and it fired right up even without charging it which is a good sign. It takes twice as long to charge the controller now, but it lasts seemingly forever now. ive used it daily for almost 2 weeks now and it still says I have 2/3 charge. I would highly recommend this battery to anyone looking to do the same mod. It fit in the old battery spot perfectly fine, but I did place a bit of foam between the motherboard and battery to keep the solder points from poking the battery body.

It does what it should

This is the same form factor as several devices I have such as a GPS but it has greater capacity. With the standard tiny plug it will easily just plug in if you manage to take the device apart without damaging it!

Battery works fine, lasts quite a while with a little Bluetooth speaker. Just be careful the polarity is correct in the connector. Mine was reversed compared to the board I was plugging it into. Reversed the wires and it was good to go.

Arrived dead and won’t take a charge.

Turned out to be a perfect replacement for the dead battery in my aftermarket Wii U game controllers.
