Baserunner

Introduction
The Baserunner is a compact field oriented motor controller (FOC) designed to fit inside the baseplate cavity of popular Hailong and Reention downtube battery packs. It has the same functionality and feature set of our popular Phaserunner motor controller, but in a smaller / flatter profile. This makes it ideal for ebike systems that can benefit from the discreteness of a controller hidden inside the battery mount.
Unlike the Phaserunner which works with up to 72V nominal batteries, the Baserunner has a maximum upper voltage 60V which restricts it to 52V nominal batteries or lower, and it has correspondingly lower current limits due to the smaller size. We have two models in production. The baserunner_Z9 model uses standard mosfets with the Z910 motor plug and has a maximum peak phase current of 55A, making it perfect for small 250-500 watt nominal hub motors. The slightly longer L10 model uses performance mosfets and can support 80A peak phase currents, making it an ideal option for medium to high power motors.

Baserunner Connector Standards
Here is the plug standard for our Version 4 and 5 Baserunner devices
|
Battery The controller itself has a short pair of + and – power leads which would be terminated to match the plugs on the battery pack. Depending on your battery these may be flat spade connectors with 4 or 5 contacts, or round bullet terminals for power and small round pins for signals. Reention downtube batteries usually use a flat 4-pin terminal, while quite a number of plug types exist for the Hailong casings. If the baserunner is purchased with a battery pack we will install the mating terminals, while if it is purchased by itself then the user would be expected to solder the wire to the terminal already present in their existing battery cradle. |
Motor The motor cable is 38 cm long and is terminated with either the Z910 HiGo style 9 pin waterproof plug or the L1019 10 pin plug. These connectors include the 3 phase wires, 5 hall wires, and one or two additional signal wires for temperature and wheel speed signals the CA3. The cable length is sufficient to reach from the downtube battery mount to the rear hub motor on most bicycle frames, but for front hub motors or extra long frames we have both 60cm and 90cm extension cables available too. |

|
6 Pin PAS / Torque A 6 Pin HiGo Mini-B or equivalent waterproof plug allows for direct hookup of a PAS or Torque sensor to the motor controller. The pin standard is compatible with the ERider torque sensors, and uses 12V rather than 5V for the power supply. This cable is not used or required when PAS or torque assist is handle via a Cycle Analyst, but it is used whith Superharness kits that have the pedal sensor plugged in directly to the motor controller. |
|
8 Pin Cycle Analyst (WP8) The Baserunner is supplied with the waterproof 8 pin HiGo plug (WP8) for running the device under the control of a V3 Cycle Analyst. If the application requires connection to an older CA-DP plug, a WP8->JST adapter should be purchased here. |
Main9 Cable The V4 and later Baserunners also feature a 9 pin waterproof plug that brings out the cables commonly used in ebike wiring topologies with a main signal harness that splits out at the handlebar into throttle, ebrake, 3rd party display, and light connectors. Note that the signal called out as Ebrake (Blue) in this diagram is also mapped as the throttle input on V5 and V6 controllers. |
|
DC Power Tap (V4 Units Only) For our customers using the V4 baserunners with a V3 Cycle Analyst, we also included by default a short power adapter from the Main plug to a 2 pin HiGo plug. This adapter not only gives a convenient power source for a rear bike light, it also shorts the regen and throttle signals together so that the CA3 can have full control over regenerative braking features . This adapter plug was discontinued with the V5 and V6 hardware which do not require regen and throttle signals to be shorted. |
|
Programming The back of the Baserunner includes a TRRS jack for connecting the Baserunner controller to a computer or USB-OTG capable smartphone using USB->TTL serial cable. This is the same cable used with the Cycle Analyst and Satiator charger, so if you already have it then great there is no need to purchase a 2nd one. When not in use, the there is a small rubber plug included to seal this hole. |
Additional Cables
There are other accessory cables that may be required when purchasing a Baserunner controller by itself and not as part of a kit from Grin.
USB to TTL Cable: The USB->TTL communication cable is required to connect the Baserunner controller to a computer in order to change and update settings. This is the same FTDI-based serial cable with a TRRS jack we use for the Satiator and Cycle Analyst. | |
9 Pin Main to TRRS: Occasionally people have damaged the main TRRS port on their Baserunner or debris inside the port has rendered it unreliable. This adapter provides an alternative access point to communicate via the Tx and Rx communication lines present on the 9 pin mains plug. | |
9 Pin Basic Mains Cable: This cable harness is required if you are not using a V3 Cycle Analyst device with the Baserunner. It provides a 3 pin throttle plug, a 4 pin ebrake plug, and a DC jack for running front lights. As well, it shorts together the on/off switch wires so that the controller is powered on with battery power. | |
9 Pin DIY Mains Cable: For more advanced users, we also provide a bare PCB version of the 9 pin mains cable that allows you to custom solder in place your own throttle, ebrake, on/off switch, fwd/rev switch wires with any connector and cable length of your choosing. Once soldered the PCB should be fully encapsulated in conformal coating or potting resin to waterproof the junction. Please Note: Due to risk of permanent controller damage from errant connections to high voltage pads, the use of the DIY mains cable negates the controller warranty. The 3 year controller warranty only applies to setups controlled with the Cycle Analyst or the premade 9 Pin Basic Mains. |
Stand Alone Model
We have also been producing a slight variant of the Baserunner_Z9 controllers that has a 90cm battery cable emerging from the same end of the controller as all the signal cables. This model was developed specifically for our Brompton Bike conversion kits for a nicer cable routing, and can be suitable for other applications where the controller is mounted externally without a downtube battery.
Software
The Baserunner controller uses the same Phaserunner software suite available for Windows, MacOS, and Linux. Note that V4 Baserunner devices require the 1.5 or later software release. The 1.4 and earlier software will produce an unrecognized device error. If using a SuperHarness Kit you MUST use software version 2.0 or later.
