Extralink LiFePO4 lithium-iron-phosphate batteries with a nominal capacity of 40Ah offer a whole range of advantages over traditional battery-based solutions made with other technologies. Extralink LiFePO4 means longer life, no maintenance, remarkable safety, lightweight, improved discharge and charging efficiency. LiFePO4 batteries, due to their long life and zero maintenance, are the best investment for years to come.
Extralink's LiFePO4 40Ah batteries do not require active maintenance to extend their life. In addition, these batteries have no memory effect, and the low self-discharge rate (<3% per month) of the LiFePO4 battery makes it possible to store them for longer periods of time.
12V lithium-iron-phosphate (LiFePO4) batteries offer high power density, making the lithium battery relatively small and lightweight. Compared to lead-acid batteries, Extralink's LiFePO4 type provides high energy density and is at least half as light. Choose Extralink LiFePO4 if you want to reduce your concerns about battery weight and size!
LiFePO4 batteries last more than 2,000 cycles while maintaining an average of 80% of their rated capacity. In comparison: a traditional lead-acid battery lasts 300-500 cycles at most. The long life makes the Extralink LiFePO4 battery an excellent economic choice.
Extralink's LiFePO4 12V lithium-iron-phosphate battery is an ideal energy storage for cars, buses, logistics vehicles, boats, emergency power, etc. due to its safety and low cost advantages. Excellent as a battery for an RV.
