9 Ah LTO cylindrical cell
LITHIUM IRON PHOSPHATE BATTERY CELL
1.Power at 25°C for 10 sec is calculated using Freedom Car discharge formulas.
2.Optimal storage temperature is 25°C.
3.In battery systems, the battery management system must enforce the voltage limits at the individual cell level.
4.The pole height of the cell is not included in the cell dimensions.
