Grin: Baserunner V6 Series

The new Baserunner V6 Series from Grin Technologies is a fully integrated, waterproof Controller for use with a variety of Hub Motor combinations, with/without the Cycle Analyst, handling up to 60V Max and 80A Peak Phase Currents (45-50A Continuous). This ensures compatibility with most eBike systems available today and programmable options for flexibility in future. All of the new V6 models include the WP8 CA Plug, with either Hailong, Reention, Tube, Fork or Plate Mounts to match your bike’s arrangement and a 38cm cable length via Z910 HiGo 9 pin plugs or L1019 10 pin. Extension cables from Controller to Motor are available in 60cm and 90cm versions, so you can choose the best mounting point for any build. Baserunner V6 with Z9 Connector (left) or L10 Connector (right) The Baserunner V6 was designed to be run ‘Headless’, so a Throttle/PAS/Torque Sensor can be plugged-in via the integrated 6 pin HiGo Connector for a lightweight set-up (see the Manual for how to do it correctly). Additional features are available by adding a Cycle Analyst, including Proportional Regen if your Motor supports it. Software updates will continue to provide further refinements. All Programming is handled via the Phaserunner Suite which also requires a computer for set-up to mate and configure, with a USB->TTL connector (sold separately and linked below). Core features are shared across Grin’s Controllers, so there is parity between Baserunner and Phaserunner.

Compatible Hub Motor Cables are: Z9 (left) and L10 (right). AKA: Z910 HiGo 9 pin and L1019 10 pin The Baserunner can be fitted inside your Battery’s Housing. The Hailong Battery Mounts fit: HL-03/HL-01 (left). The Reention Battery Mounts fit: DP-9C/DP-6C (right) Here is a Baserunner installed under a Hailong Enclosure with L10 Connector The Baserunner can also be installed externally for improved airflow with Tube, Fork and Plate Mounts (left to right), suiting eMTB, Brompton, Cargo and more. Baserunner Version History: V3 Device: The V3 update took place in 2020 and had the exact same connector standard as the V2 model, but featured an internal demux circuit to support combined temperature and speed signals in the Z910 motor plug. This demux circuit is backwards compatible and fully supports motors that use the white wire as just a speed sensor or just a temperature sensor. V4 Devices: Released in late 2021 as the V4 Baserunners with a substantial overhaul. The V4 units continue with the 8 pin CA-WP plug but also have a 9 pin Main signal plug to provide optional support for conventional ebike displays. The independent 3 pin JST throttle plug has been removed, and replaced instead with a 6 pin HiGo connector that can be used for direct hookup of a throttle, a PAS sensor, or a Torque sensor, even without a CA3 device in the system. Due to electronic part shortages, a mosfet substiution was required in the L10 devices made them vulnerable to mosfet failures with 48V and 52V battery packs as a result of voltage spikes caused by electrical ringing. The V4 Baserunner_L10’s were therefore only recommended for systems running 36V and lower. V5 Devices: From June 2022 reworked V4 baserunner PCBs on hand in order to have better mosfet robustness with 48V and 52V battery packs, and also updating the Cycle Analyst plug wiring so that the throttle output is wired to Analog Input 2 (Brake1) and not Analog Input 1 (Throttle). This eliminated the need to have the 9-2 pin adapter cable for shorting ebrake and throttle pins to achieve regenerative braking control via the Cycle Analyst. Otherwise all wiring and plug details remained identical to the V4 units.
