The Power of Your LiFePo4
Solar Energy Home

LiFePO4 Lithium Iron Phosphate battery packs are extremely powerful, capable of providing high discharge rates even at elevated temperatures. Safety is improved over other lithium ion chemistries due to its thermal and chemical stability. LiFePO4 cells are long lasting and boast a 10+ year shelf life due to its slower decline of energy density. Battery packs are capable of providing 5000+ cycles, which could outlast the product it is powering!

Our New Articles

Coremax Technology is exploring exciting new projects in the realm of lithium-ion batteries. With numerous advantages over other battery chemistries, lithium batteries have established themselves as a safe, reliable, and long-lasting energy storage solution. Unlike some other lithium battery types, they are devoid of the risk of thermal runaway or catastrophic meltdown.

Lithium-ion batteries boast an impressive cycle life, with some manufacturers offering warranties for up to 10,000 cycles. Additionally, these batteries have high discharge and recharge rates, capable of C/2 continuous discharge, and a remarkable round-trip efficiency of up to 98%. No wonder they are rapidly gaining popularity in the industry.

Lithium Iron Phosphate (LiFePO4) is an ideal choice for energy storage and Coremax Technology is exploring its full potential through innovative new projects.
