Standard and custom LiFePO4 battery packs
Lithium Iron Phosphate batteries first appeared in the early 2000’s and are increasingly used in robotics and energy storage. Lithium Iron Phosphate (LiFePO4) batteries have a nominal voltage of 3.2V and are an excellent solution for applications requiring a lightweight, high capacity battery with a long lifespan and stability at high temperatures.
Lithium Iron Phosphate is based on Lithium-Ion chemistry. One of the major advantages of LiFePO4 over other Lithium-Ion chemistries is its thermal and chemical stability, which greatly improves the safety of the battery.
LITHIUM IRON PHOSPHATE CELLS
At Enix Power Solutions, we have been building custom battery packs over the last 10 years using cells from leading Lithium Iron Phosphate battery manufacturers such as K2 Energy and A123.
We also offer our own range of reliable LiFePO4 cells under the NX brand:

LITHIUM IRON PHOSPHATE APPLICATIONS
LITHIUM IRON PHOSPHATE VS LITHIUM-ION
These two chemistries share many advantages and disadvantages however there are significant differences. Lithium Iron Phosphate offers a higher number of charge/discharge cycles, up 1,500 cycles at 100% DOD (depth of discharge) and 2,000 cycles at over 80% capacity.
One of the major advantages of Lithium Iron Phosphate over Lithium-Ion chemistries is its thermal and chemical stability, which greatly improves battery safety. The LiFePO4 cathode is intrinsically safer than the LiCoO2 or the manganese cathode. The Fe-PO bond is stronger than the Co-O bond, so that if misused (short circuit, overheating, etc), the oxygen atoms are much more difficult to remove. As a result, Lithium Iron Phosphate cells are much more difficult to inflame when mishandled (especially during charging). It is commonly accepted that LiFePO4 cells do not disintegrate at high temperatures. However, despite this, there is still a risk of thermal runaway in cases of continuous overcharging or incorrect charging procedures.
LITHIUM IRON PHOSPHATE VS LEAD ACID
LiFePO4 offers a much longer cycle life, approximately four times longer than Lead Acid (1,500 cycles for LiFePO4 vs. 400 cycles for Lead Acid), and a wider range of operating temperatures (-20°C – +60°C). Lithium Iron Phosphate batteries offer a higher energy density and are twice as light as Lead Acid.
