Baserunner V6 User Manual
Rev0
The “Low Voltage Cutoff (Start)” and “Low Voltage Cutoff (End)” values can be
set just above the BMS cutoff point of your battery. The table below shows typical
values for regular lithium-ion cells.
Nominal Pack Voltage 24V (7s) 36V (10s) 48V (13s) 52V (14s) 72V (20s)
Low Voltage Cutoff 20.3 V 29.0 V 38.0 V 40.6 V 58.0 V
Max Regen Voltage 29.4 V 42.0 V 54.6 V 58.8 V 84.0 V
If you are using a V3 Cycle Analyst, we recommend leaving these values at the
default 19.5/19.0 volts and use the CA3’s low voltage cutoff feature instead. That
way you can change the cutoff voltage without a computer if you ever need to
swap batteries.
7 Additional Parameter Editing
For most users, applying the default parameter covered in Section 6 will be
sufficient for great ebike performance. If you have specific needs beyond this,
then many other behaviours can be tweaked through the various tabs.
7.1 Motor Autotune
Basic Setup tab
If the motor being driven is not available in our list of motor presets, then it will be
necessary to configure the controller parameters manually.
Please Note: When tuning your Baserunner V6 to a motor via the software suite,
it is essential that your bike is propped up so that the powered wheel can rotate
freely, both forwards and backwards. With a rear hub motor, also ensure that the
cranks can rotate freely.
The Autotune routine from the Basic Setup tab can automatically detect motor
parameters like the motor speed constant (kV), resistance of one motor phase to
neutral (Rs), and the inductance of motor phase to neutral (Ls).
