Iron Phosphate
Custom LiFePO4
Battery Pack Manufacturer
Lithium Iron Phosphate, often abbreviated as LiFePO4 or LFP, has established itself as one of the battery technologies offering a compromise balance between safety, lifespan, cost, and reliability. For engineers and design firms, LiFePO4 chemistry represents a stable and proven solution. At Enix Power Solutions (EPS), the engineering and design of custom LiFePO4 battery packs follow a rigorous process: designing the exact architecture your industrial application requires, without compromise.
Are you looking for a technical partner to develop your custom battery pack? Our design office can analyse your specifications.
Why Choose
Enix Power Solutions
For this Technology?
As pioneers in the integration of LiFePO4 technology, we have been designing and manufacturing battery packs based on this chemistry since 2009. With over 15 years’ experience, we have established a recognised track record in the design, integration and industrialisation of reliable, high-performance and sustainable battery solutions.
Our positioning as a LiFePO4 battery pack manufacturer is based on complete technological neutrality. As a system integrator, our approach involves selecting, for each project, the most suitable components – whether battery formats (cylindrical, prismatic, pouch cells) or battery management electronics – in order to precisely meet our customers’ specific needs and constraints. We carry out a detailed analysis of the charge/discharge behaviour, internal resistance, dispersion and ageing of each cell to ensure the pack’s reliability throughout its entire life cycle.

this technology be used?
LiFePO4 technology is a particularly well-suited solution when intrinsic safety, electrochemical stability, and cycle life are key criteria.
We recommend the use of Lithium Iron Phosphate for equipment in the following sectors:
A Rigorous Approach
We approve the use of LiFePO4 only after a detailed analysis of your specifications. If your specifications change, we will adjust our technical recommendation accordingly.
The Mistake to Avoid
We approve the use of LiFePO4 only after a detailed analysis of your specifications. If your specifications change, we will adjust our technical recommendation accordingly.

The Mistake to Avoid
Sticking to a single cell technology at the start of a project. Analysis of your actual requirements should guide the choice of chemistry and cell format, not the other way round.
Benefits for a custom battery pack
must be considered in the context of the constraints of your application:
-
Energy density
LiFePO4 chemistry has a lower energy density than NMC Lithium.
-
Long-term storage
LiFePO4 can be stored for long periods, provided our recommendations are followed.
-
Safety
There is no such thing as zero risk in the energy sector. However, the electrochemistry of Lithium Iron Phosphate is stable, and all precautions are taken to minimise risks.
-
Robustness
LiFePO4 chemistry is structurally robust.
-
Temperature control
Thermal performance is in line with the standards of professional lithium technologies.
-
Technological maturity
Developed in 1996, Lithium Iron Phosphate technology is now mature but continues to evolve. We incorporate the latest generations of cells from battery manufacturers.

USE CASE
Replacing a lead acid battery with a LiFePO4 solution
Client context
Our client was operating an industrial application powered by lead-acid batteries. As part of an initiative to improve performance and reduce maintenance requirements, they wished to migrate to lithium technology.
Technical constraints of the project
- Significantly reduced footprint: the space available for the new battery was only 50 per cent of that of the existing lead-acid pack.
- Trickle-charging mode.
- Precise monitoring of the battery’s state of charge (SOC) and state of health (SOH).
- Integration of CAN bus communication.

Case Study | a custom Solution Developed by EPS
As specialists dedicated to the design of custom LiFePO4 battery packs,
we carried out the design, sizing and manufacture of a complete unit incorporating:
|
Electrical architecture |
Rated voltage of 25.2 V (8S16P) with a capacity of 44.8 Ah. |
|
Cells used |
26650 Cylindrical format (3.2 V / 2.8 Ah). |
|
Integrated electronics |
A 140 A BMS specifically designed for LiFePO4 chemistry. This system manages the pack’s safety, calculates SOC/SOH, handles the CAN communication interface, and puts the battery into sleep mode and reactivates it in the event of inactivity. |
-
Results and benefits
The choice of LiFePO4 offered a much safer integration than NMC lithium chemistry for this industrial application. The battery pack offers a significant reduction in size whilst increasing service life and flexibility of use (trickle charging validated). The final system is fully compliant with regulatory and standards requirements: UN38.3, IEC62619, CE marking and functional safety.

FAQ
In which situations should lithium iron phosphate technology be used?
LiFePO4 is recommended for industrial projects (robotics, medical applications, instrumentation) where electrochemical stability, safety and cost control take precedence over absolute compactness.
What transport constraints need to be taken into account for LiFePO4?
Like all lithium batteries, LiFePO4 battery packs must be certified as compliant with UN38.3 regulations in order to be transported legally and safely.
