BATTERY SAG
Become familiar with the amount of battery sag full throttle causes in eco mode, normal mode, and sports mode. Sag
is described as the amount of electricity drawn depending on how much throttle is given. On a colder day it is not
uncommon at full throttle for the voltage sag to be 7 volts and on warmer days for it to be between 4 volts to 5 volts.
•
Each mode limits the amount of sag.
•
Eco mode will help prevent cut offs by reducing the sag amount.
•
The amount of throttle given directly controls the amount of sag.
BATTERY CUT OFF
When the amount of battery sag falls below 51 volts, the Onyx CTY2 will turn off. Cut off occurs because the
battery management system is programmed to protect the batteries from damage from low voltage.
LOW BATTERY LEVELS
The Onyx CTY2 battery does not discharge in a straight constant line, it is more like a curve where the top of the
charge above 85% and the charge below 15% deplete faster. The entire 71.4 volts are available but spread out and
discharged at a different rate towards the top of the charge and bottom of the charge.
The 23 Ah battery will cut out at 51 volts. If the battery is unbalanced, it can cut out at a higher value, depending on
the degree in different voltages between the individual cells.
