The LifePO4 battery Pack made by 26650 single cell
The period of warranty is one year from the date of shipment. TAC BATTERY guarantees to give a replacement in case of cells with defects proven due to manufacturing process instead of the customer abuse and misuse.
The batteries should be stored at room temperature, charged to about 30% to 50% of capacity.
We recommend that batteries be charged about once per half a year to prevent over discharge.
