In this Instructable, I will show you, how to make a LiFePO4 Battery Pack for applications like Off-Grid Solar System, Solar Generator, Electric Vehicle, Power wall, etc. The fundamental is very simple: Just to combined the number of LiFePo4 cells in series and parallel to make a bigger pack and finally to ensure safety by adding a BMS to it.
Lithium Iron Phosphate batteries are charged in two stages: First, the current is kept constant, or with solar PV that generally means that we try and send as much current into the batteries as available from the sun. The Voltage will slowly rise during this time, until it reaches the 'absorb' Voltage, 14.6V in the graph above.
The fundamental is very simple: Just to combined the number of LiFePo4 cells in series and parallel to make a bigger pack and finally to ensure safety by adding a BMS to it. The LiFePo4 cells come in a variety of sizes, but here I have used the 32650 type. My Book : DIY Off-Grid Solar Power for Everyone
Before diving into the assembly process, it's important to understand why LiFePO4 batteries are preferred for DIY projects: Safety: LiFePO4 batteries are more stable and safer than other lithium-ion chemistries due to their chemical properties, which significantly reduce the risk of thermal runaway and explosions.
Use sturdy straps or brackets to hold the battery in place and prevent it from moving during transportation or operation. This will help protect the battery from damage and ensure its longevity. Proper wiring and connections are essential for the safe and efficient operation of your DIY LifePO4 battery box.
No equalize charge is required for the LiFePO4 battery. If equalize stage cannot be disabled from your charge controller, set it to 14.6V or less, so it becomes just a regular absorb charge cycle. Temperature Compensation: LiFePO4 batteries do not need temperature compensation!
It can be powered from any USB port or USB standard power supply adaptor. It does not use any difficult-to-handle surface mount device (SMD) or a miniscule chip. LiFePO4 batteries are best known for their safety because of their extremely stable phosphate-based chemistry. Also, these newer type of lithium batteries are inherently non-combustible.
Lithium battery banks using batteries with built-in Battery Management Systems (BMS) are created by connecting two or more batteries together to support a single application.

Multiple lithium iron phosphate modules are wired in series and parallel to create a 2800 Ah 52 V battery module. Total battery capacity is 145.6 kWh. Note the large, solid tinned copper busbar connecting the modules together. This busbar is rated for 700 amps DC to accommodate the high currents generated in this 48 volt DC system.
Lithium iron phosphate LFP is a common and inexpensive polyanionic compound extensively used as a battery cathode. It has a long life span, flat voltage charge-discharge curves, and is safe for the environment. Sun et al. prepared 3D interdigitated lithium-ion microbattery architectures using concentrated lithium oxide-based inks .
The LFP battery uses a lithium-ion-derived chemistry and shares many advantages and disadvantages with other lithium-ion battery chemistries. However, there are significant differences. Iron and phosphates are very common in the Earth's crust. LFP contains neither nickel nor cobalt, both of which are supply-constrained and expensive.
