Cutoff Voltage – This is a critical option to understand and used to protect Lithium or M1 batteries from being over-discharged, which will shorten the life, cause damage to the battery, or even result in Fire or Personal Injury.
When using NiMH batteries you do not need to set a cut of voltage to protect the batteries. NiMH batteries typically stop operating your vehicle before any damage occurs. If you are using more than 6-cell NiMH batteries, you must adjust the cut of voltage, for example if you are using an 8-cell pack of NiMH batteries you would use a cutoff of 5.6V volts (8 x 0.7V = 5.6V). If you are using fewer cells of NiMH batteries, a cutoff voltage of 4.0V will provide power for your radio system to operate and reduce the chance of losing control.
v No Cutoff The choice for racing used along with quality NiMH battery packs.
v Customize Voltage Cutoff (for NiMH Batteries) you can select a starting cutoff voltage of 4, 5, 6, 9 or 12 volts. Then using the up/down to the right of the voltage you can increase the voltage stepping up 0.1V between the selectable settings. Following the above example for an 8-cell NiMH battery, you would select 5.0V and then increase 6 steps up to 5.6V.
