40 Ah LTO cylindrical cell
NANO LITHIUM TITANATE BATTERY CELL
1 Power at 25°C for 10 sec is calculated using FredomCar 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 Cell terminal heights are not included in the stated cell dimensions.
