EEMB Lithium Polymer battery 3.7V 1100mAh 903042 Lipo Rechargeable Battery Pack with wire JST Connector-confirm device & connector polarity before purchase

Easy to install works well and delivers all of the power I need for my RC boat. Charges up well and it was well packaged and delivered in a good time and at a great price.

I received it the following day. It was easy to fit and it came with a leaflet with other batteries and dimensions.

Although the capacity was the same as my previous one it was much larger but thankfully still fitted into my dash cam (just). So far, very pleased.

Make sure what connector you need. This won't fit the Heltec v3 LoRa boards, for which I purchased it for.

Original battery had 'ballooned', this one charges a lot faster an lasts a lot longer.

Be aware that the battery doesn't have any protection for overcharge

Great value

I am amazed that I have come across a battery that hold the milliamps that is printed on it case, I test all my batteries nowadays as there are so many overblown claims out there, after a five charge / discharge cycle, I got a 540mA reading from my tester, I'm sure if I had done another cycle it would have reached the full capacity, I installed it as a replacement battery into a Cosmo robot, which is working fine after over a month by a very decerning but picky owner.

Replace a lower capacity battery, 240ma, in my favorite old bluetooth headphones with this one and I am now getting more than 5x the battery life, or about 2.5x when the headphones were new, so I am very happy.

This battery is an exact replacement for the PS4 Hori Mini Wireless Controller (PS4-133, PS4-133A, PS4-134, and PS4-134A models). My controller suddenly died on me only giving me a brief white flash when plugging it in but being completely non-repsonsive afterwards. If this is the situation you're in, this battery can bring that controller back to full functionality. A triwing screwdriver is needed to open the controller by unscrewing the screws on the back, but once that is done, you will see that the battery is taped to the back cover of the controller with a wire plugged into the other side where the circuit boards are. Carefully remove the plug from the old battery and replace it with this new one ensuring that the red cable is aligned with the "+" terminal printed on the controller's circuit board. After that, swap out the adhesive and electrical tape from the old battery onto the new one and insert/stick the new battery in the corner where the old battery was tucked away.

batterie pour sirène solaire extérieur, fonctionne très bien, bonne charge, dehors depuis trois aucun problème.

Om din enhet behöver en 3-polig JST-kontakt är detta batteri inte för dig. Annars är det en bra produkt för pengarna.

監視カメラの電源として利用しています。 充放電コントロールモジュールを使って、日中は太陽光パネルで充電し、その電力で監視カメラを動かしています。小型でかつ十分な容量があるため、この電池自体を充電することもなく、連続して運用できています。４箇所のハンダ付けとケースに格納するだけの簡単な作業で作成できたため、非常に満足しています。 欲を言えば、取り付けられているターミナルコネクタと対になるコネクタが付属していればと思います。
