LP103454

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

Used these to power an arduino board (make sure you check the polarity, as i had to flip mine) It's nice and compact for a portal gun build i recently completed the electronics for.

Super good enough 👍 Used for a Meshtastic node build.

Great quality and capacityI will comeback for more batteries for my projects

Owning an old Wii U console which uses a proprietary battery is a problem, especially when the options for replacement are limited.So after buying some cheap replacements from China which claimed high mAh but only lasted 30 minutes I thought I would look for a DIY alternative.I used the old battery as a donor for the charging circuit which was desoldered after a little struggle with the plastic case. The EEMB battery is very neat, smaller than the Wii U battery but slightly thicker. I then checked the polarity of the EEMB battery and soldered on the charging circuit.Due to the thickness of the new battery I only used half of the plastic case but it won't be seen with the cover on.The battery charged fine and lasted for nearly 1hr 30 in the gamepad. So very happy with this little 2000 mAh battery.

Battery hasn't lasted 1 month.

Long life and easily rechargeable. Check connection polarity is suitable before plugging in and if necessary swap leads around in connector

Great service, quickly delivered. Had to switch polarity on connector for my use case but not an issue.
