    Battery recommendations LG MJ1 ? GO or NOT GO

    We found cheap ones at alibaba for 2.5 to 3.5 USD per cell. But when we chose only among factories/sellers that ONLY have Class-A Brand batteries in their product catalogue, we asked now to get 400 Pieces for 3USD per cell (down from 3.27USD). Don't know what the reply will be. They are ALL...

    Battery recommendations LG MJ1 ? GO or NOT GO

    Hi, I'm about to get batteries for assembling a triangle lithium battery for my 3000 watt ebike (yes I use a micro-dot welder...). I'm thinking of using LG MJ1 due to their 3500mAh capacity, also due to their 10A maximum continuous drain, and because I can get them fairly cheap. And i like that...

    Cycle analyst shuts down momentarily (suspect the THUNE)

    I did some adjustments in the CA-DPS "advanced setup", and Now; instead of it shutting down after 2 kilometres, it ran for 11 kilometres after the adjustments. I read in the manual that the pre-configured settings are for a bike between 300-600watts. So by turning down many configurations, I...

    Cycle analyst shuts down momentarily (suspect the THUNE)

    Hi, I have a new ebike setup and a problem has occurred. After about 10 kilometres (7 miles) the cycle analyst shut down. The Vshutdown for the THUNE is set to 10 V (default). This is my bike setup: DD Crystalyte HS3540, GRINTECH sensorless 40A 72volt controller, CA-DPS (with external...

    2 controllers in paralell for one hub motor, is it possible?

    Yeah, I can experiment with the oldest controller and see if I can change the FET's into those Crystalyte are using in the controlller for the CROWN motor (60A or 90A). And I can also check out if some of the capacitors need to be changed. Endonuclease

    2 controllers in paralell for one hub motor, is it possible?

    Yes, by a second thought, I totally agree..... Just a de-synchronization of a few milli-seconds will perhaps be tolerated by the controllers, but the battery will be also shorted in those fractions of milliseconds - something that can't be good at all for the battery. Especially when you think...

    2 controllers in paralell for one hub motor, is it possible?

    Hi, I recently got me a Crystalyte H4080 motor. I run this on a Crystalyte 72 volt 45 A sensor/sensor-less controller (I run it in sensor-less mode and works well). But the case is that I now have two such identical regulators, after I removed two blown MOSFETS (an identical regulator from my...
