Just been reading a statement regarding the charging of a TN 110 Ah Lithium Battery and trying to get a grip of the terminology involved.

"Electrical Characteristics"

Nominal Voltage 12.8v

Nominal Capacity 110Ah@ 0.2C

" Charging mode - At 0℃~45℃ temperature, charged to 14.6V at a constant current of 0.2C5A, and

then,changed continuously with constant voltage of 14.6V until the current was not

more than 0.02C5A"

" Charging Current - 21.6 Amps"

"Max, Charging Current - 54 Amps"

Ok for arguments sake lets use 100Ah to make the sums easy , the nominal capacity and the term 0.2C5A are what I need an understanding of please?
