Features. High efficiency output: standard discharge is 2~5C, continuous high current discharge can reach 10C, instantaneous pulse discharge (10S) can reach 20C; Good performance at high temperature: the internal temperature is as high as 95 °C when the external temperature is 65 °C, and the temperature is up to 160 °C when the battery is discharged. The structure of the battery is safe and intact. Even if the inside or outside of the battery is damaged, the battery does not burn, does not explode, and has the best safety; Excellent cycle life, after 500 cycles, its discharge capacity is still greater than 95%; No damage to zero volts after overdischarge; Fast charging; low cost; No memory effect: Rechargeable batteries work under conditions of constant exhaustion, and the capacity will quickly fall below the rated capacity. This phenomenon is called memory effect. Nickel-metal hydride and nickel-cadmium batteries have memory, but lithium iron phosphate batteries do not have this phenomenon. No matter what state the battery is in, it can be used with charging, no need to discharge and recharge first. The volume of the lithium iron phosphate battery is small and light, and the volume of the lithium iron phosphate battery of the same specification is 1/3 of the volume of the lead-acid battery, and the weight is 1/3 of the lead-acid battery. No pollution to the environment, the battery does not contain any heavy metals and rare metals (Ni-MH batteries need rare metals), non-toxic (SGS certification passed), no pollution, in line with European ROHS regulations, is an absolute green battery. There is a large amount of lead in the lead-acid battery, and if it is improperly disposed after disposal, it will still cause secondary pollution to the environment, and the lithium iron phosphate material is free from pollution during production and use.
