Victron Energy LiFePO4 Battery 12,8V/150Ah Smart- BAT512115610

Lithium-iron-phosphate (LiFePO4 or LFP) is the safest of the mainstream li-ion battery types. The nominal voltage of a LFP cell is 3,2V (lead-acid: 2V/cell). A 12,8V LFP battery therefore consists of 4 cells connected in series; and a 25,6V battery consists of 8 cells connected in series

A lead-acid battery will fail prematurely due to sulfation

• If it operates in deficit mode during long periods of time (i.e. if the battery is rarely, or never at all, fully charged).
• If  it is left partially charged or worse, fully discharged (yacht or mobile home during wintertime).
• A LFP battery does not need to be fully charged. Service life even slightly improves in case of partial charge instead of a full charge. This is a major advantage of LFP compared to lead-acid. Other advantages are the wide operating temperature range, excellent cycling performance, low internal resistance and high efficiency (see below). LFP is therefore the chemistry of choice for very demanding applications
• With integrated cell balancing 
  
• Can be parallel and series connected
• Bluetooth app available to monitor cell voltage and temperature
