Custom Lithium Iron Phosphate Battery Packs & Individual Battery Options

Lithium iron phosphate (LiFePO4), also called LFP, is one of the more recently-developed rechargeable battery chemistries and is a variation of lithium-ion chemistry. Rechargeable lithium iron phosphate batteries use LiFePO4 as the principle cathode material. Despite having a lower energy density than other lithium-ion chemistries, lithium iron phosphate batteries can provide better power density and longer life cycles.

HOB Custom Power (DBA House of Batteries) is your premier lithium battery assembler. We manufacture custom lithium iron phosphate battery packs and assemblies for many applications. Our battery design team uses the latest mechanical and electronic design tools to optimize the reliability, safety, and manufacturability of your custom LFP battery packs.  Our lithium iron phosphate batteries provide your battery-powered products with cost-effective and dependable rechargeable power.

Lithium Iron Phosphate Cell Characteristics

Items to consider before choosing any battery for your project include the following:
  • Voltage
  • Capacity
  • Power Rating
  • Operating Temperature
  • Size
  • Cost
  • Availability
Once these items are well understood, then a cell/battery can be selected that provides the requirements necessary for the project to be effectively completed. If your project requires more voltage than your battery provides it is possible to increase the voltage by connecting multiple cells in series. Also, by connecting cells in parallel, you can increase the overall current capacity (run time) of the battery.

Pros and Cons of Lithium Iron Phosphate Batteries 

As a custom lithium battery assembler, HOB Custom Power produces custom lithium iron phosphate battery packs that can be used for a wide range of custom applications. Our rechargeable lithium iron battery packs use a lithium-ion-derived chemistry that shares many of the same advantages with other lithium ion battery chemistries.

Custom LFP Battery Pack Advantages

Compared to other battery options, custom lithium iron phosphate battery packs provide superior thermal and chemical stability. This allows for improved safety characteristics over lithium-ion batteries that utilize less-safe cathode materials. Rechargeable lithium iron batteries are also virtually incombustible due to mishandling during the charge and discharge processes, which means that they can handle higher temperatures without significant damage. Other major advantages for LiFePO4 when compared to other Li-ion chemistries include higher rate discharge capability and longer cycle life.  

Custom LiFePO4 Battery Pack Disadvantages

The energy density of custom lithium iron phosphate battery packs, both by energy and volume, is somewhat lower than that of LiCoO2 cells and batteries. However, while LiFePO4 cells have lower voltage and energy density than other Li-ion cells, this disadvantage is offset over time by a slower rate of capacity loss (greater calendar-life) when compared with other lithium-ion battery chemistries, such as LiCoO2 cobalt or LiMn2O4 manganese spinel.  

Like other lithium-ion cells, lithium iron cells and batteries are available in Energy and Power types that provide either better power or energy characteristics, depending on whether a longer run time or high rate discharge is required.

Applications for Lithium Ion Phosphate Batteries

Rechargeable lithium iron battery packs have been a popular choice for electric vehicles thanks to their fast-charge and hi-rate discharge capabilities and long cycle and calendar life.  Power tool manufacturers have also adopted the LFP chemistry for the same reasons. Medical device manufacturers and defense contractors are adopting the LFP chemistry for its inherent safety. Some of the industries that regularly utilize LFP batteries, include:
  • Electric automobile manufacturers
  • Power tool companies
  • Medical device manufacturers
  • Military
