850 mAh Polymer Lithium Ion Battery


Do you need a new battery for your RileyLink?  SparkFun has discontinued these from their store so we will try and supply them to the community.

This is the same battery we ship included with the RileyLink’s. These are very slim, extremely light weight batteries based on the new Polymer Lithium Ion chemistry. This is the highest energy density currently in production. Each cells outputs a nominal 3.7V at 850mAh. The Battery comes terminated with a standard 2-pin JST-PH connector – 2mm spacing between pins. This is the battery connector used on the RileyLink so you will just need to plug it in and charge it up.
