12V Slimline LiFePO4 12.8V 50Ah rechargeable lithium battery

12V Slimline LiFePO4 12.8V 50Ah rechargeable lithium battery 2021-05-15T07:48:28+00:00

Project Description

12V battery pack – Lithium-Iron-Phosphate (LiFePO4) – 50Ah
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)
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
