    Batteries and Charging
    Hello everyone! I'm having trouble establishing in what year and month my Midac EW100 traction batteries were made. I have this code (339330) which is written on the top of the battery and I don't know how to read it and find out the year and month when they were built. I'm using them on a...

  5. Anyone Have Some Real World Data?

    Technical Discussion
    I'm a little unclear on (among other things) battery capacity requirements. This uncertainty has arisen due to comments I keep seeing from people about LiFePO4 cells with a C3 rating being marginal for a street EV. For example: Someone recently said that a Hi-Power 100A cell with a C3 rating...
