48V 1000Ah Deep Cycle LFP Lithium Battery 50KWH For UPS Backup / Energy Storage
LiFePO4 Cell Advantages
- Long cycle life more than 4500 @ 85%DOD
- Much safe LiFePO4
- Low self discharge < 3%
- Advanced lithium ferro phosphate
- Environmental friendly, No cobalt, no toxicity, no hazards, no heavy metals
- 98% efficient
- Excellent Temperature resilience-ambient temperatures up to 50°C will not affect the life.
- High Discharge Current,1C is standard, higher currents are also acceptable up to 3C continuous with negligible loss in efficiency and cell life.
- Lighter and smaller than lead acid battery
- Free of charge memory
- Stable charge and discharge performance
- Wide temperature performance
- Fast charging, about half an hour to be fully charged
- Require no change to a lead acid battery charging system
- No gasses during charge, free of leakage and pollution
- Easy installation and carrying, can be carried and installed in any direction

After-sale Service
For the warranty and after-service we will follow the following principle.
Warranty year(s) for this model of battery pack is specified by supplier. In the period of warranty, there is any
problem as the following description, we will take responsible for the replacement and repair.
• The whole battery pack can not be charged or discharged.
• Under the standard condition for testing, capacity is not same as nominal Ah. It is less than 80% in the first
year, or 70% in last warranty year (if the last warranty year is provided as warranty period).
• There is liquid leakage.
• There is some damage on battery pack’s case and accessory because it is caused by the battery.
There is any situation like the following description, we will not take responsible for the warranty and after-sale
service.
Expired warranty period.
• Customer didn’t follow the manual instruction, which is resulted in battery damage.
• Customer dismantles and convert the battery pack, which is not guided by the professional people.
• There is some apparent scratches and trace on the case of BMS.
• Customer has right to choose the charger, while customer should get confirmation from supplier about
technical details of Charger, to avoid misoperation.
