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 demanding applications.

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 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.

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. Very useful to localize a (potential) problem, such as cell imbalance.

Our LFP batteries have integrated cell balancing and cell monitoring. Up to 5 batteries can be paralleled and up to four 12V batteries or two 24V batteries can be series connected, so that a 48V battery bank of up to 1500Ah can be assembled. The cell balancing/monitoring cables can be daisy-chained and must be connected to a Battery Management System (BMS).


Powerful and Long-Lasting:

LiFePO4 batteries offer exceptional power density and longevity.
80% Depth of Discharge (DoD): 2500 cycles
70% DoD: 3000 cycles
50% DoD: 5000 cycles

Results in a lifespan of approximately 15-20 years based on daily usage, outperforming traditional AGM batteries.

Compact and Lightweight:

Weighing only 14kg, the 100Ah LiFePO4 battery is over 50% lighter and smaller than its lead-acid counterparts.
Ideal for applications where weight and space are critical considerations, such as campervans and boats.

Use Cases:

Suitable for deep discharge, making it ideal for applications with over 90% discharge of total capacity.
Perfect for off-grid enthusiasts, campervans, boats, and users with regular full-time energy consumption needs.

Smart Functionality:

Built-in Bluetooth capability enables wireless monitoring and control.
Use the VictronConnect app to monitor cell voltages, temperature, and alarm statuses conveniently.

External BMS Requirement:

Requires an external Battery Management System (BMS).
systems with VE.Bus connections (e.g., MultiPlus), the VE.Bus BMS and
corresponding RJ45 cables are needed. Otherwise, the smallBMS is

Operating Conditions:

Discharge: -20°C to +50°C
Charge: +5°C to +50°C
