Lithium 12V Battery Pack- Lithium Iron Phosphate (LiFePO4) 300Ah

  • High lifespan: two thousand cycles and more (see chart)
  • Deep discharge allowed up to 100%
  • Ultra-safe Lithium Iron Phosphate chemistry (no thermal run-away, no fire or explosion risks)
  • Embedded BMS (Battery management system): improve lifespan and secure the battery
  • No lead, no heavy metal, no toxic element
  • Calendar life > 10 years
  • Excellent temperature robustness (-20 °C up to + 60 °C)
  • Constant power during discharge (Very low internal resistance)
  • Energy efficiency > 96 %
  • Very low self-discharge (<3% per month)
  • No memory effect
  • About 50% lighter and 40% smaller than equivalent Lead AGM battery with the same usable energy
