• ♥ Lithium iron phosphate life (LiFePO4) characteristics: Compared with other lithium batteries, its theoretical life is 5 to 15 years, or 2000 to 8000 cycles. When not in use, the monthly self-discharge loss is only 3%-5%, and the performance is superior. The charging cycle refers to the entire process from full charge to full discharge and then to full charge.
• ♥ Application range: Suitable for DIY RV battery, solar energy storage, electric tricycle, electric vehicle, high-power inverter, communication base station, mobile power station, electric vehicle, emergency power UPS, electric motor, electric tricycle, power generation and four-wheel electric Car etc
• ♥ Quality Assurance: We will match and balance all batteries before delivery to ensure that the internal resistance, voltage and capacity of the batteries are fully matched and balanced before delivery.
• ♥ About charging: It is characterized by no memory effect and fast charging. You don't need to put it fully and then charge it. For lithium iron phosphate batteries, the recommended standard charging current is 0.2C, and the maximum charging current is 0.5C.
• ♥ About safety and environmental protection: Lithium iron phosphate battery is environmentally friendly, non-toxic, does not cause pollution, does not contain heavy metals, and is a true green battery. Safety comes from the stability of the positive electrode material and the reliable safety design, which will not cause an explosion even in a severe collision.

• The newly purchased lithium battery will have some surplus, and the remaining power needs to be used up and recharged. After 2-3 times of normal use, the lithium battery activity can be fully activated.
• Lithium batteries do not have a memory effect and can be charged as they are used, but it should be noted that lithium batteries cannot be over-discharged. Over-discharge will cause irreversible capacity loss.
• When the instrument is not in use, be sure to remove the battery and store it in a dry and cool place.
• Pay attention to the operating environment of the lithium battery: the charging temperature of the lithium battery is 0 ℃ ~ 45 ℃, and the discharging temperature of the lithium battery is -20 ℃ ~ 60 ℃.
• Use a regular matching lithium battery charger to charge the battery, do not use inferior or other types of battery chargers to charge the lithium battery.
• Do not mix the battery with metal objects to avoid short circuit.

NOTE: How to store lithium batteries that have not been used for a long time.

1. Lithium batteries should be charged with 50%~80% of electricity if they are not used for a long time, and they should be taken out of the instrument and stored in a dry and cool environment, and the batteries should be charged every 3 months to avoid excessive storage time and battery self-discharge. Too low, causing irreversible capacity loss.
2. The self-discharge of a lithium battery is affected by the ambient temperature and humidity. High temperature and humidity will accelerate the self-discharge of the battery. It is recommended to store the battery in a dry environment between 0 ℃ and 20 ℃.
