    Torque Sensor Cycle Analyst V3

    Hi What is the best and reliable torque sensor compatible with Cycle Analyst V3? I plan to use it in combo with Efneo GTRO so I can pedal at higher speed too. It will be nice if I can buy it in Europe or Aliexpress. This are the measurements of Bottom Bracket I got with Efneo:

    Sabvoton SVMC96120 max. Regen start voltage

    I got two replys from Aliexpress sellers: Hello The overload voltage of 96120 is 115V, which can meet the regeneration of 24S battery. However, it is recommended that you set a lower regenerative current, because the high-voltage regenerative current will be relatively large, and it is easy to...

    Controller Options for 24s - 36s (100V - 150V) 200A Range

    Hi I am in process of building a powerful E-Bike. There are many controller options for 20S battery. On current E-bike I use Sabvoton SVMC72150 with 22s battery in combination with CA V3. I like to know for my new build if there are any good options for controllers for 24s - 36S (100V - 150V)...

    Sabvoton SVMC96120 max. Regen start voltage

    Hi I like to ask if anyone here know what is the max voltage on SVMC96120 for Regen still kicks in when I pull the E-Brake or use variable Regen? Before I build a 24S LiPo battery I like to know if Regen still kicks in over 100V or only bellow 100V?

    Sabvoton SVMC072150 controller review, variable regen *PICS*

    Hi Thanks for reply. So the best option is to remove two cells from the battery pack and make it 20S 84V full charge. Pity I did not know this before when I already changed battery pack from 24S to 22S to lower max voltage for SVMC72150 :? I do not use flux weakening because 80kmh is enough...

    Hi I have to change my old failed controller on my e-bike with SVMC72150 which I have on stock for new E-bike project. I have 22S battery charged to 22x4.15v = 91,3V. On old controller regen braking worked from this voltage without problem. On SVMC72150 the regen start working below 86 volts. I...

    Hi Neil Your box looks very nice. Mine is covered with carbon fiber look film to keep it discrete ( no shining aluminium ). Your hand made torque plates looks very good too. Can you still remove the packs individually or are the balance leads all hard wired to the d-sub? I dont need open the...
