EEMB 3.7V 2000mAh 103454 Lipo Battery with JST Plug 2mm, 4PCS

These hold the charge well, and are compact. Great for RnD with Arduino boards - make sure you confirm pin-out of the batter connector and swap over the terminals in the plug if your dev board requires it.

Decent battery for the price, runtime has so far been good in use, lasting around about a day depending on if the LoRa device I'm using it with has the GPS module active or not, polarity wasn't an issue in my case because I was changing the connector anyway but it is always a good idea to check, as I had to discharge it using something else before changing the connector to fit my project I did have to swap the polarity, this is easy to do if you are careful and don't allow the two contacts to short out. For my project the size of the battery was not an issue as I had purchased it prior to 3D printing a case so I could use the sizing as a guide, however again something to check if you're replacing a battery in an existing product. The battery does have an onboard cell protection board under the orange tape where the wires go in, for these types of battery it is important that there is some kind of over discharge protection and this does work as it should, after I did the initial discharge to make it safe to work on to integrate into my project I checked this out with a multimeter. All in all, it's a good value battery and because I have a similar project lined up I'm more than likely going to buy another one

Working well as replacement battery pack for my active loudspeaker. Used in series / parallel to make a powerful replacement. If you try this, make sure to individually charge each one to the exact same voltage before trying to interconnect. I did use a battery management chip in this assembly.

Battery matched the size specified by the code (10x34x54mm), it has sufficient voltage when plugged in, so no issues charging or having to jump start it, etc, worked great for an ESP32 based project

As described & a direct repair replacement for the battery in my music stand lamp, which on investigation (as it didn’t seem to be holding chord a charge) was SWOLLEN 😳. Luckily I’d caught it in time.

Good performance and recharge works as expected.

Extremely disappointed at the lack of quality control. The battery is swollen.

I needed a replacement battery for a rechargeable DAB radio which had gone defective Found this on Amazon Perfect physical dimensions and spec`s, have been using for a few weeks now and works perfectly This company manufactures a whole range Would not hesitate to use this company`s products again, very satisfied Fast delivery from Amazon as always

perfect replacement for the inkbird iBBQ-4T's battery.

Works for Rak 19007/19003. LxWxH(mm) 34.5 x 56 x 10.6 for the 2000 mAh

Besser als gedacht für meine bastel Projekte. Angaben zur Kapazität und abmaße werden gehalten!

Buena calidad, bien empaquetado, batería precargada... Buen producto

Tutto bene
