Top cell was 2.7 but most were at 2.6

Starting voltage 2.6 quickly dropping to 2.5 volts.

End voltage of low cell 1.6v bounced back to 2v.

This makes me feel so much better about my build. 130farenheit motor when run for miles. 212 wh per mile average. 50mph top speed. And 32 mile range. How's your speed after midway through pack?

Tomberlin is a pig. Lots of rolling resistance. Small wide tires.
I had to sell my LTO battery pack to make deal.
Starting over now using a Volt 28s module. Configured double 14s.
