Cell Selection
  • Specification selection (dimensions/capacity/voltage);
  • Charge / discharge rate selection (standard/high rate);
  • Cycle life;
  • Excellent safety and stability;
  • Intrinsically safe requirement;
  • Low temperature(-30℃/-40℃), wide temperature (-40℃-85℃);
  • High energy density, low internal resistance, extended battery life.
