Project Description

3.2V Battery Pack- Lithium Iron Phosphate Lifepo4 Battery Pack 3Ah

High lifespan: more than 2000 cycles

Deep discharge allowed up to 100%

Ultra-safe Lithium Iron Phosphate Chemistry

Embedded BMS: improve the lifespan and secure the battery

No Lead, no heavy metal, no toxic clement

Calendar life > 10 years

Excellent temperature robustness (-20 to +60 °C)

Low Peukert’s losses( energy efficiency > 96%)

low self-discharge (<3% per month)

No memory effect

Lighter and smaller than equivalent lead-AGM battery with same usable energy
