BlckRck2014 Posted July 30, 2022 Share Posted July 30, 2022 Sadly there seems to be a v1.5 controller board. I have one. I have also worked on v1 and v2 units. Here is how to quickly tell them apart: v1 has three capacitors that are placed next to each other (almost touching). No metal backing to the board. With a fan. v1.5 has three capacitors that are placed in a spaced out format. There is metal backing to the board. No fan. v2 has only two capacitors and they are larger. There is metal backing to the board. No fan. The display board is different. 1 Quote Link to comment Share on other sites More sharing options...

At the moment GW is most likely trying to stop delivering spare parts and firmware updates to #1 series early, I'm most happy to be wrong, but untill we get some fair information from the manufacturer.. russian telegram we trust Edited August 2, 2022 by Kutvelo Quote Link to comment Share on other sites More sharing options...

Better medium mode by far. Soft mode now mostly works except at slow speeds. But holy crap I feel for people who tried V1 and don't get a taste of the real master. Its night and day. Its like they were using RS firmware or something and now it's all master. So much power! Also switch was so easy I just recieved mine from Wheel Rider store...

Its like they were using RS firmware or something and now it's all master. So much power! Also switch was so easy I am confused with those board versions. From what I know, there is a control board v1.0, v1.5 and v2.0. According to a previous post, the difference between v1 and v2 can be determined by the number of capacitors on the control board (as shown in the illustration below) What I do not understand is that user Wgm said On 7/3/2022 at 6:15 PM: “Switched to V2 control board and it's totally different. Way more easy power…” But the v2 control board is supposed to be NOT COMPATIBLE with the v1 board (v2 boards expect 67V (134/2V) battery packs). Question to user ‘Wgm’ (and all others who might understand more than I do): -> Do you mean ‘Switched to v1.5’ ? instead of v2 control board? -> If you really mean switched to v2, did you change your battery packs? Question for everyone: -> How do we recognize if I have v1.5? is it really the presence of a fan? The comment above from Wgm suggest there should be a real difference between v1 and v1.5? My understanding is that v1.5 does not have a fan; it might be v1 without any fan connected or it might be a different board. My goal is to understand if I have a board that can be switched to a better board without the need to replace the battery packs.

Michel T., confused It's prob V1.5 that got with more spaced out capacitors and a metal bottom that I replaced. If shown pics I can tell them each apart. I didn't replace anything else. I will say the firmware that came with 1.5 or whatever it is def feels more responsive. Quote Link to comment Share on other sites More sharing options...

His is only compatible with Clarkpads. Apart from installing another seat, has anyone tried anything to mitigate that yet ? What sort of thing could we use to make it more durable ? I suppose we could always go nuts with the gaffa tape, but it would be really nice if there was a much less crappy looking alternative...

Sai and Grizla pads fit fine, I tried all 3 (Clark’s included) and like Grizlas marginally better but Clark’s feels great too, just a tad harder than Grizla pads for me.

Raptor Posted August 8, 2022 Share Posted August 8, 2022 (edited) Hi ! I Ok . Now it is completely silent! The slide bushings needed very little tightening. The gyro seems a bit too sensitive and overreacts even with very little play. Care must be taken when tightening the tensioning screws of these bushings! If you try a little harder, the suspension sliders get stuck!!! ( Has anyone else experienced this behavior and sound with the Begode Master and is this a feature or defect of this model ? ) Edited August 10, 2022 by Raptor Quote Link to comment Share on other sites More sharing options...

It is hard to be certain for us viewers that this sound does not come from the wood beams under the wheel. But if this sound comes from the Master, I would look into replacing the motor.

BleepBloopBlop Posted August 9, 2022 Share Posted August 9, 2022 I'd guess that is a controller issue. My EXN had similar symptoms. They thought it was either a controller or hall sensor issue. The warranty covered my replacement controller. Quote Link to comment Share on other sites More sharing options...

mike_bike_kite Posted August 9, 2022 Share Posted August 9, 2022 Do we get a picture of what the current packs look like? And does anyone know why the new set up better than something like the current 1800Wh packs? Quote Link to comment Share on other sites More sharing options...
Tawpie Posted August 9, 2022 Share Posted August 9, 2022 (edited) 47 minutes ago, mike_bike_kite said: And does anyone know why the new set up better Without knowing anything more than the appearance of the "redundant" word and referring to paralleling packs, the thought is that it should be better because the OG design allowed a failure in any single pack to shut power completely off. Paralleling 'should' reduce the odds of pack-failure induced catastrophic power loss by half. But the devil is in the details. EDIT: one of many hiding spots for the devil Given that "b"is the new arrangement, if a single pack should get disconnected, there is a sibling 'leg' to continue to hold up the total voltage and supply current. The leg with the failed pack is out of circuit. However, this single leg is now asked to supply the current that was shared with the now-dead sibling leg so you don't want to ride for long in this configuration. It's quite within the realm of imagination that a BMS fuse in the surviving pack or the one it's connect to could blow and that has the effect of a complete power cutoff. We used to call this a cascading failure mode. Edited August 9, 2022 by Tawpie 2 1 Quote Link to comment Share on other sites More sharing options...
