Victron Energy LiFePO4 Battery 12.8V / 25.6 Smart

Sale!

  • High energy density, Smart LiFePo4 Technology.
    • With integrated cell balancing
    • Can be parallel and series connected
    • Bluetooth app available to monitor cell voltage and temperature

    Why lithium-iron-phosphate?
    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.

Rugged
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 LiFePo4 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 LiFePo4 compared to lead-acid.
Other advantages are the wide operating temperature range, excellent cycling performance, low internal
resistance and high efficiency (see below).
LiFePo4 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 leadacid battery is 80%.
The round-trip energy efficiency of a LiFePo4 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 LiFePo4 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?
LiFePo4 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.

Bluetooth
With Bluetooth cell voltages, temperature and alarm status can be monitored.
Very useful to localize a (potential) problem, such as cell imbalance.

  • 3 Year Warranty

Requires one of these BMS-es:

  • VE.Bus BMS – recommended for systems with Victron inverter/chargers.
  • Victron miniBMS – recommend for use in small systems.
  • Battery Management System BMS 12/200 – recommend for use in Automotive and Marine systems having DC-loads and Alternators.
  • Smart BMS CL 12/100 – recommended for use in Automotive and Marine systems having DC-loads and Alternators.
  • Lynx Smart BMS– recommended for use in larger systems with the Lynx distribution system.

Battery Management System (BMS)
The BMS will:
1. Generate a pre-alarm whenever the voltage of a battery cell decreases to less than 3,1V (adjustable 2,85-3,15V).
2. Disconnect or shut down the load whenever the voltage of a battery cell decreasesto less than 2,8V (adjustable 2,6V-2,8V).
3. Stop the charging process whenever the voltage of a battery cell increases to more than 4,2V.
4. Shut down the system whenever the temperature of a cell exceeds 50°C.
