1. High capacity 20ah for one cell, you can assebmled higher capacity with less single cell
2. 3.2V standard voltage meet various equipment
3. Wide range of operating temperature; 0-45 degree,
4. Long operating time 2000times , usually keep 3-5 year
6. Low self-discharge rate (less than 2% per year at 20°C).the battery remain capacity is 70% for original capacity after stock one year
Main Applications :
The high capacity lifepo4 cell can be used for various EV E-CAR protable ESS
Back up for boat: refrigerators, ice maker, dishwasher, electronics
RF device

Cautions in use
To ensure proper use of the battery please read the manual carefully before using it.
. Handling
. Storage
. Disposal
Battery operation instruction
Discharging current
The discharging current does not have to surpass this specification book stipulation the biggest discharging current, the over sized electric current electric discharge can cause the battery capacity play to reduce and to cause the battery heat.
Electric discharge temperature
The battery discharge must carry on in the ambient temperature scope which this specification book stipulated.
Storing the Batteries
The battery should store in the product specification book stipulation temperature range. If has surpasses above for six months the long time storage, the discharge capacity will decrease sharply.
Period of Warranty
1 year from the goods were shipped out from facory ,Because batteries utilize a chemical reaction, battery performance will deteriorate over time even if stored for a long period of time without being used. In addition, if the various usage conditions such as discharge, ambient temperature, are not maintained within the specified ranges the life expectancy of the battery may be shortened or the device in which the battery is used may be damaged by electrolyte leakage. Please change the battery in time.
