Project Description

6.4V battery pack – Lithium-Iron-Phosphate (LiFePO4– 4500 mAh
• High lifespan: two thousand cycles and more
• 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)
• Very low Peukert’s losses (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 same usable energy

• Certification : CE, RoHS, UL, UN 38.3
