EEMB 3.7V Lipo Battery 1100mAh 603449 Rechargeable JST 2.0mm,1-Pack

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.

Is as described. The JST connector is not wired for microcontrollers but RC things so be aware.

It does what it should

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.

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!

Used this to install in my Dual GPS sensor,the battery charges fine and works for a few hours , but if it sits for more than a few weeks, the battery doesn't hold the charge. The original battery that came with the unit would hold charge for many months between use.

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

Ersatzakku , funktioniert sehr gut

Perfecto!

This battery replaced a 3.7v 1000mAh. The new battery is a 1100mAh battery so you should know the battery physical size will be different from a 1000mAh unit. You should measure the dimensions of your original battery to the one you want to buy. In my case the new battery was 2mm thicker 3mm wider and 2mm longer. I then measured the space where the battery is to be installed. The battery was to replace the old battery in a blue tooth speaker. The battery just fitted into the original location with no room to spare. The new battery works 100% with the added bonus I have 10% more reserve power.
