Hello Vitesze!
Thank you I was wondering if 7.0 was a better match.
Thanks for the quick reply 
Our devices don’t use a the battery and instead use a large capacitor.
I’m worried if the E-Series doesn’t have this improved, getting it replaced will cost more as its soldered to the board. (Can’t just replace the Electron). Lets see if anyone has thoughts on how this works on the E-Series.
