OUTDATED - K1 CAN Monitor & programmer for Bafang motors with CAN bus - check K1 BlackBox 3


100 W
Feb 12, 2015
Hello builders.

www.fb.com/K1eBikes presents portable and simple K1 CAN Monitor - no need computer. Works ONLY with Bafang motors with CAN bus (green connector to display with "house" shape connector - M300, M400, M420, M500, M510, M600, M615, M620, M800). Rechargable battery (works cca 8h on one charge, or can be run also from USBC).

Idea was to monitor motor temperature, then I have added also other monitor parameters: Speed, Energy consumption per km, Voltage, Current, Power, Used energy over coulomb counter (SOC should be more accurate), Temperature of stator windings and controller. Also can setup max assistance speed, wheel size and circumference.

If you interested send an email to CanMon@K1eBikes.sk - specify which country you want to ship. Then I will reply you with information and details email. First 2 email orders to be shipped now. Next production batch will be in 1 month - please be patient, I am building it by hand and will manage according demand. Price: 120 Eur + Shipping (will keep shipping as low as possible).

K1 CAN Monitor is determined for testing purpose only. One disadvantage - small buttons - you can get used to it. ;)

Any way to monitor the BMS, of the battery?

TI have a IC solution: https://www.ti.com/product/BQ76940
Il was asking sortof the same question the other day, but nobody seams to know: https://endless-sphere.com/forums/viewtopic.php?f=14&t=30091

Atm, I sure I dont have CAN support from my motor or controller (300w 8fun hubmotor).
Hi, It could be possible to change the power of the différents levels, 1 to 9 or 1 to 5 ?
