It might cut If you try more than that. Be carful gouing higher. I fuse might as well pop. And they need to be re-soldered.

Never tried, because my damn charger has just 7.8A, but I'm still looking for a lightweight 12A charger. So I ended up resolving this. The V4 master charge controller only connects the batteries if the charger matches the battery voltage. It won't connect eg. 134v, the charger first needs to match the battery voltage before it connects. It also has a current limiter around 13a iirc - so if the current is too high it also cuts off. I resolved both issues by setting my charger to 0 current (voltage cuts off to 0), then slowly turning current back up to the desired level. This causes the voltage to again rise steadily, "catching" the battery voltage and getting the charge controller to connect. Then I set the current to about 12A, and get a respectable ~2hr fast charge from empty (~1.5hr including only the fastest charging portion, really) Quote Link to comment Share on other sites More sharing options...

The limit has apperently been set to different values on different boards. I guess 12A can be possible, 1 Quote Link to comment Share on other sites More sharing options...

Seems a bit steep on the £££ but even so I am considering getting a pair myself... as much as I have got used to and quite like being so high up, the wind over here is playing merry hell with my high CoG, and this might just sort that out...

Now I no longer have any problems riding seated in strong crosswinds. 2 questions if I may... 1. Were yours easy to fit - do we have to disassemble the machine much to get to them ? 2. I am surprised this makes much if ANY difference to seated riding in wind; isn't your CoG as low as it can get when seated, to the point where pedal height isn't making a difference ? I was expecting it to make a big difference to standing rides, but thought seated riding might be largely unchanged. Interesting ! Oh, and if yours are 3cm lower, do you think the extra 2 here will further improve the situation, or do you reckon 5 cm is a bit much to drop ? I'd hate to spend £150+ only to replace wind problems with pedal-scraping ones ! Edited January 5 by Cerbera Quote Link to comment Share on other sites More sharing options...

I didn't even think about the benefit of more comfortable seating, that would be a well received side benefit as even though the EX isn't a small wheel, with me at 186cm and my 50 year old knees I could do with all the help I can get!

EUC Custom Power-Pads Posted January 5 Share Posted January 5 (edited) I was thinking the same thing. An improvement in seated riding was not even on my wish list and I was so surprised that this problem was also a thing of the past that I would have paid €500 for it. I was hoping to get close to the riding behaviour of my MSP, better cornering, especially more stability in fast aggressive cornering, better acceleration, better braking, better uphill riding and more stability in strong crosswinds (standing) All my wishes were fulfilled and on top of that there was more stability in crosswinds when seated and generally a better sitting position thanks to 3 cm more distance between pedal and seat. Assembly was relatively simple. As far as I remember only the pedals off and pedal hanger screws. I'm not sure if I had to loosen the 8 lower screws of the battery boxes, but I don't think so. I had also thought back and forth for a long time about whether 30 or 45 (EUCYOU only has 30, 45 or 60mm). But I didn't want to get to the same height or even lower than my MSP pedals when the Master is fully compressed. I mainly ride offroad and have to say that 30mm is the perfect compromise for the lost ground clearance and all the benefits, I'm glad I didn't go for the 45mm. 30mm and your Master is perfect. 45, 50 or even 60mm might be good for street riding if you can sacrifice ground clearance and low lean angle in corners in favour of even more stability.

I'm 54 and 183cm with shitty knees and ankles. But with the lower pedal hangers and a 30/40mm Seat booster it is very easy and comfortable to sit on the Master.

Cerbera Posted January 5 Share Posted January 5 Yes, this has all been most illuminating ! I DO mainly do street rides, really very few steep kerbs, steps, and only occasional off-roading. Sounds like I should give 5 cm a go ! Quote Link to comment Share on other sites More sharing options...
Cerbera Posted January 5 Share Posted January 5 (edited) 1 hour ago, EUC Custom Power-Pads said: I was hoping to get close to the riding behaviour of my MSP Sounds like you and I have a similar history. Before the Master arrived I had had 4 years on my MSV3 and felt blissfully confident that I had mastered riding that machine, meaning the Master came as big shock to me with its utterly different ride feel, and distinctively non-planted, tippy feeling, which I found a real contrast to the MS3. A year later I am used to it now, and don't generally have problems getting about with similar levels of confidence but maaaan, do I have to slow right down to remain stable in really ANY level of wind, and even with this much time I still don't quite get the 'planted' and 'organic leg extension' feel I had from the smaller wheel. I think I am talking myself round to finding the order button ! Oh, there isn't one - we have to email. Nope - not even that - only telegram, which is annoying - I don't have, or want that !

EUC Custom Power-Pads Posted January 5 Share Posted January 5 I rode my MSP 3 years, because I knew that all those new wheels with high COG and high pedals will come with lot of downsides, but my ankles couldn't accept offroad anymore and suspension was the only way to go. 😅 Yes, EUCYOU is only on Instagram or Telegram. But be careful, there is a fake account called EUC_YOU and Instagram does nothing to close the account. This is the right guy: https://www.instagram.com/eucyou/ I can ask him if he has a e-mail address for you? 1 Quote Link to comment Share on other sites More sharing options...

Planemo Posted January 6 Share Posted January 6 And if he doesn't want his email going public, I'd appreciate a PM with it too if you manage to get it! I don't do IG, Telegram or anything else either. Ideally he would have the ability to just purchase off his website, hopefully he will go that way if business peps up. I truly hope so, his does some real nice CNC stuff and I love CNC stuff Quote Link to comment Share on other sites More sharing options...

Panzer04 Posted January 8 Share Posted January 8 Having a Master V4 on hand, I can confirm it's between 41 and 42kg, within the accuracy of a bathroom scale. It's definitely on the chunky side.

I'll have to try out an older master when I get the chance and see how noticeable the difference is. It's my first heavy wheel, I'm looking forward to trying out other wheels now and seeing the difference. It certainly makes the 16X feel like a toy in comparison in terms of how easy it is to maneuver and throw around - Master is a truck with 2-3x the turning radius by comparison. (bearing in mind I'm fairly competent at getting the 16x to turn pretty sharply nowadays - talking <1m turning radius vs 2-3m) 1 Quote Link to comment Share on other sites More sharing options...

EUCzero Posted January 13 Share Posted January 13 I think my Master v2.4 is about 40kg with pads and all (fairings as well), so 43 is to be expected I guess. Metal battery cases V.S. super flimsy plastic shit I have on mine. Quote Link to comment Share on other sites More sharing options...
