Why lithium-iron-phosphate?

Rugged

• 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 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 efficiency of a LFP battery is 92 %.
• The charge process of lead-acid batteries becomes particularly inefficient when the 80 % state of charge has been reached, resulting in efficiencies of 50 % or even less in solar systems where several days of reserve energy is required (battery operating in 70 % to 100 % charged state)
• In contrast, a LFP battery will still achieve 90 % efficiency under shallow discharge conditions.

Size and weight

• Saves up to 70 % in space
• Saves up to 70 % in weight
  

Expensive?

• LFP batteries are expensive when compared to lead-acid. But in demanding applications, the high initial cost will be more than compensated by longer service life, superior reliability and excellent efficiency.

• With Bluetooth cell voltages, temperature and alarm status can be monitored.
• Instant readout: The VictronConnect App can display the most important data on the Device list page without the need to connect to the product.
• Very useful to localize a (potential) problem, such as cell imbalance.
