## Description

EEMB Lithium Polymer battery 3.7V 2000mAh 103454 Lipo Rechargeable Battery Pack with wire JST Connector for Bluetooth Speaker and Dashcam-confirm device & connector polarity before purchase: desertcart.co.uk: Electronics & Photo

Review: Decent lithium battery at a decent price - 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
Review: Good replacement battery - This was perfect for a small receiver a ATS25X2 receiver that needed a replacement nicad battery. fitted inside the receiver case nicely, seams to last a reasonable time proportionate to the original battery.
