Time for new batteries

I have been struggling with thundersky batteries for way to long and have decided to try a Lipo pack in the bike

Here is a picture compilation of the process from cells to pack in the bike. As of this writing she still isn't back together but will be in a few days.
The cells come from Hobby King Turngy four cell 5AH hard case packs. I'm building this up as a 8P 28S pack or 115 volts @ 40AH. We'll see how these fair over time and hopefully without any incidents

A second side benefit is the bike is losing over 50 pound of weight!
