EEMB Lithium Polymer battery 3.7V 1100mAh 603449 Lipo Rechargeable Battery Pack with wire JST Connector-confirm device & connector polarity before purchase

works great and good value

Great replacement of the battery in an old car hands free Bluetooth speaker found in storage after years which was no longer charging or powering up. Had to snip away the wire connector plug to allow for direct soldering to circuit board but this was straight forward using snips. The battery arrived precharged at 70% level confirmed once connected to Bluetooth and offers a higher maH to the OEM battery replaced. Size and fit are great as expected.

You could tell the quality in this battery straight away the weight is heavier than cheaper none brand ones I bought and this holds the charge way better. I say cheaper this was about the same price as the other one... tge quality was just a cheaper knock off china tat. Highly recomend this company and there batteries and will defo be using them for every purchase in tge future! I'm just happy that I have finally found a company and I dont have to keep searching throuvh the minefield of pot luck.

This cell replaces a battery in a scale - it's the same output / rating as the battery it replaces while being a bit smaller and the connectors a bit larger than the original - it was easy to feed the old battery's connector wires into this new cell to test it, and fitting it into the space for the old battery also not a problem. I have not used this cell long enough to be able to assess how well/long the charge lasts - will update (if that's possible) once that's known, but worked out of the box; have charged it to full capacity, and seems to be working since received in daily use for the past week. 10 quid is a lot for a rechargeable cell, but much much less expensive than replacing the unit that is out of warranty and that the manufacture said the battery is not consumer replaceable.

Charges faster the lead weight a fraction of lead holds way more charge than lead. I'm never going back I have 3 bat packs for my wheelchair the other 2 will get changed to lithium so happy for the change. More charging cycles just better in everyway

Purchased to replace a dead battery in a mini bluetooth keyboard and it now works perfectly 👍

I'm glad I checked the polarity of the connector before I connected it to my Arduino microcontroller boards as they were reversed. The battery was delivered as described as described in the product listing but three of my boards (genuine Arduino and an Adafruit) all had the same polarity. I managed to pull the pins out of the plug and swap them. I was going to but a charger but I don't know what the standard is for these batteries. Do RC applications use a different polarity vs Microcontroller applications?

A great battery to replace a failed (blown/inflated) battery on a MUX Mighty Plug Pro. Just snip the connector off (without shorting the battery out!) and solder the wires to the contact points after removing the old one! It is slightly smaller than the original in length, however the battery that comes in the NUX from the factory is a custom battery, so an exact replacement is not commercially available. Very happy!

I used this to replace my headset of 200mA and it lasted 30 hours play time in one charge

Excellent produit correspond à la description parfait pour mon projet je suis très satisfait l'autonomie n'est pas horrible du tout très satisfaisant très contente pour un prix abordable je recommande

prima litium batterijen voor goede prijs capaciteit verhouding.
