Up Board Battery Voltage
I'm currently working on a project where we are using an UP Board for mobile data collection. Essentially, the subject wears the UP Board on their belt or in a bag while going through their day. To make this process mobile, we have started using the S.USV UPs board supplied by Olmatic seen here:
Unfortunately neither the stock 300mAh nor the 3000mAh battery run the UP Board long enough for us to complete a data collection session (10-12 hours).
My question: One obvious solution is to use a higher capacity battery, although with the stock voltage being 3.7V these batteries seem to be very hard to find. Is it acceptable to use a higher voltage battery along the original battery connection or the other, external power connection? General insight from others trying to use the UP Board in a mobile capacity would also be great. Thanks.
