EVE LF280k 3.2v 280Ah LiFePO4 Battery Compression Force Parameters
The maximum stacking force the cells can bear when assembling a module.
Compression force > 50kN, defects are generated inside the battery. Compression force >100kN, the battery will leak. Therefore, the compression force of the battery should not exceed 50kN, otherwise the battery may be damaged.
EVE LF280k 3.2v 280Ah LiFePO4 Battery Cell Long-term Storage
After the battery is charged, it should be used as soon as possible to avoid loss of usable capacity due to self-discharge. If storage is required, the battery needs to be stored in a low SOC state. The reco mmended storage conditions are 30%~40%SOC 0~25℃ ≤60%RH.
EVE LF280k 3.2v 280Ah LiFePO4 Battery Cell Transportation
Battery for shipping should be packed in boxes with the SOC of 30%~40%. Severe vibration, impact, extrusion, sun and rain should be prevented during shipping. It’s applicable for transportation tools inc luding truck, train, ship, airplane, etc.
EVE LF280k 3.2v 280Ah LiFePO4 Battery Cell Operation Precautions
- It is forbidden to inversely charge. Correctly connect the positive and negative poles of the battery, and reverse charging is strictly prohibited.
- It is forbidden to over-discharge. During the normal use of the battery, in order to prevent over-discharge, the battery should be charged regularly to maintain the voltage above 2.8V.
- It is strictly forbidden to immerse the battery in water. When it is not in use, it should be placed in a cool and dry environment.
- It is forbidden to use and leave the battery next to heat and high temperature sources, such as fire, heater, etc.
- Please use a specific charger for lithium-ion batteries when charging.
- During usage, it is strictly prohibited to reverse the positive and negative terminals of the battery.
- Do not throw the battery into the fire or heat the battery.
- It is forbidden to use metal to directly connect the positive and negative terminals of the battery.
- It is forbidden to transport or store the battery with metal, such as hairpins, necklaces, etc.
- It is forbidden to knock,throw, step on, or bend the battery.
- It is forbidden to directly weld the battery.
- It is forbidden to directly pierce the battery with nails or other sharp objects.
- It is forbidden to use or place the battery at extremely hot environments, such as direct sunlight or hot weather in vehicles.
- It is forbidden to use it in places with strong static electricity and strong magnetic fields.
- If the battery leaks and the electrolyte splashes on the skin, clothes, eyes, mouth, nose, etc., immediately wash the affected area with running water and send to a doctor for treatment immediately, otherwise it will cause serious harm to the human body.
- If the battery emits peculiar smell, heat, discoloration, deformation, or any abnormality during use, storage, or charging, stop using it.
