Lithium Battery 12VDC - 180AH - Smart LifePO4 - Drop Ship Only for $150

Victron Energy Lithium Battery Smart batteries are Lithium Iron Phosphate (LiFePO4). They are available in capacities of 12.8 V or 25.6 V. They can be connected in series, parallel, and series/parallel so that a battery bank can be built for system voltages of 12 V, 24 V, or 48 V. The maximum number of batteries in one system is 20, which results in a maximum energy storage of 84 kWh in a 12 V system and up to 102 kWh in a 24 V¹) and 48 V¹) system. 

A single LFP cell has a nominal voltage of 3.2 V. A 12.8 V battery consists of 4 cells connected in series and a 25.6 V battery consists of 8 cells connected in series.

Why lithium-iron-phosphate?

Rugged 

A lead-acid battery will fail prematurely due to sulfation: 

• If it operates in deficit mode during long periods (i.e., if the battery is rarely, or never 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 a 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 demanding applications.

Efficient 

• In several applications (especially off-grid solar and/or wind), energy efficiency can be of crucial importance. 
• The round-trip energy efficiency (discharge from 100 % to 0 % and back to 100 % charged) of the average lead-acid battery is 80 %. 
• The round-trip energy eff
