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.

An LFP battery does not need to be fully charged. Service life even slightly improves in the case of partial charge instead of a full charge. This is a major advantage of LFP compared to lead-acid. Other

An LFP battery does not need to be fully charged. Service life even slightly improves in the 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.

Victron lithium batteries must be installed with a Battery Management System (BMS) to:

1. Generate a pre-alarm whenever the voltage of a battery cell decreases to less than 3,1V (adjustable 2,85 - 3,15 V).
2. Disconnect or shut down the load whenever the voltage of a battery cell decreases to less than 2,8V (adjustable 2,6 V - 2,8 V).
3. Stop the charging
