Application
EV and Back Up
The buyer can assemble it with bigger capacity and voltage with require.
Engineer Drawing
Period of Warranty
The period of warranty is one year from the date of shipment. HK TAC guarantees to give a replacement in case of cells with
defects proven due to manufacturing process instead of the customer abuse and misuse
Storage of the Batteries
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.
