hey randyc1, love your build, you should have included all these DIY goodies in your first post! imo these details are whats it all about!
concerning your battery: you seem to be using 2 different types of cells? your parallel green pack will most likely drift relative to the blue, so I guess (hope) you are using a BMS?
my build thread on ES: https://endless-sphere.com/forums/viewtopic.php?f=35&t=72026&sid=708fbd95e09b3518f8802cd57d24072d#p1088195
even though I didnt have any problems (yet), I will probably use these insulation rings to protect the “+”-side of the cells a little more in future. ordered a whole bunch of them -> http://www.ebay.de/itm/331832123025
also, I will in future fixate cells of a parallel pack with some hot glue, so they wont start to wear out their insulation hull by working on each other (also didnt happen yet, but might).
ive seen a 2 times now (by being stupid mostly), what these crazy currents can do if you short one of these batteries. each time I had a 4mm bullet connector in my hand and each time it was basically GONE, and I mean GONE and not just black and bent.
