【Service life over 8 years】Lithium iron phosphate batteries have a service life of over 8 years or 5000 charge-discharge cycles and are maintenance-free throughout their entire service life. This effectively saves costs and time when replacing batteries. In comparison, lead acid batteries (AGM) have a service life of approx. 2-3 years or 500 charge-discharge cycles.
Safe and environmentally friendly battery: Compared to other lithium batteries, LiFePO4 batteries have higher chemical stability. Even during destructive puncture tests, the battery cells remain fire and explosion resistant. The integrated 300A BMS module effectively ensures a balanced voltage state of the battery cells and protects against hazards such as overcharging, over-discharge, over-current, short circuits and extreme temperatures.
Excellent compatibility and expandability: the 12 V 300 Ah LiFePO4 battery can easily replace almost all lead batteries. Up to four batteries can be connected in series and in parallel to form a large 48V 1200Ah battery pack to meet the capacity requirements of photovoltaic systems.
All batteries are delivered locally, avoiding long delivery times. The batteries come with an 8-year warranty. Should a defect occur during the warranty period or the capacity falls below 80% of the rated capacity, you will receive a full refund or a free replacement.
Advanced LiFePO4 technology: LiFePO4 batteries are characterised by an extremely high energy density and are 70% lighter than lead batteries with the same specifications. The maximum continuous charge and discharge currents reach 300 amps, the pulse currents exceed 600 amps. As a result, LiFePO4 batteries offer extremely high performance and remarkable fast charging capability.
