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

works really well when you reverse the wires to make sure you're not plugging earth into live and vice versa.

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.

Works well and I am using it to power a raspberry pi zero.

Bought this as the specs matched the battery in my Acaia coffee scales and the description said it was suitable for them, but the connector is the wrong size; the Acaia use a smaller connector. I swapped the connector over from the old battery was a bit of a hassle. Otherwise the battery seems good, no issues with it so far. A relatively cheap way to get your scales working again.

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?

For projects

Convenient size, good capacity, great value.

Modified the plug as it wasn't compatible but the battery spec was what I wanted
