Power Sonic�s PSL series of LiFePO4 batteries have been designed and developed to provide a lighter, higher power and longer life solution to lead acid batteries. LiFePO4 batteries last longer and can produce 10 times the number of cycles than a typical lead acid battery. At only 40% of the weight of the equivalent lead acid battery our LiFePO4 range is ideal for those applications that need to be lighter and more mobile but deliver the same power.
