    Selecting the best value 18650 cells

    25r's... that does seem to be a good choice, I may even bump it up to 6P 15Ah... With the 35A rating they should hold up best at ~3A/cell I want something that will last me a few years.

I included a pic to show my train of thought. I'm riding a stock PB710, about 10Km round trip to work and back, in Canadian winter...
