Self-made lithium iron phosphate battery pack

Why are LiFePO4 batteries preferred for DIY projects?

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.

How are lithium iron phosphate batteries charged?

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.

Are lithium ion batteries the new energy storage solution?

Lithium-ion batteries have become a go-to option for energy storage in solar systems, but technology has advanced, a new winner in the race for energy storage solutions has emerged: lithium iron phosphate batteries (LiFePO4).

How long does a LiFePO4 battery last?

Life Cycle: Lithium batteries also have a longer cycle life than lead-acid batteries. LiFePO4 batteries can also last a very long time. Good quality batteries are rated around 3000 cycles, at a full 100% charge/discharge cycle. If you did that every day it makes for over 8 years of cycling!

How do you charge a lithium ion battery?

Connect BMS balance leads to each cell’s (+) terminal. Test voltage balance with a multimeter before sealing. Wrap cells in fish paper. Seal connections with heat shrink tubing. Mount pack in a ventilated case (prevents thermal runaway). Charge at 0.5C (e.g., 50A for 100Ah pack) using a LiFePO4-compatible charger.
