battery recommandation

  1. Batteries and Charging
    -- Hello, I have some question about battery. I'm looking for 3.3v (20ah or 10ah)Lithium phosphate battery. I'm planning to make a 48vdc 20ah BMS. >.< I think Tenergy or Bmi is good. :) Could you tell me which one is better? or another ? Thank you~~^-^
