@desperado I think I've been by there in Chagrin before. If you're ever in the Toledo area, checkout Secor Park, pretty empty most of the time and the trails transition from crushed limestone to dirt to grass, prime trails for OW...
I only weigh 150 lbs so clearly I get more range because of the weight difference. However see what even a 1 lb air pressure increase to 20 PSI does to your range. Also you will find that Mission is more efficient. Whenever I need the range, I go Mission. Whenever I hit the trails and need the responsiveness, I select Delirium. I do wish I can change the shapings on the fly rather than have to slow down to 1 mph and fiddle with my App to switch. Changing the shaping to the terrain would also maximize my range.
My only thought was perhaps the low tire pressure caused the motor to overload? Just wanted to see if anyone else had similar experiences. As I said, I ride this around the city and if I take a nose dive at the wrong time, it could be a very bad day for me. Thanks.
It definitely could be tire pressure related. Less pressure means more rolling resistance. Also, Mission does not respond quickly to small dips and bumps, and will increase the chance of a momentary nose dip.
@maxjaypower I am wondering if you are experiencing low battery pushback and your app is not reading the battery % correctly. My board dies when I have 20% left according to the app but I have traveled 7 miles on it so I am getting the full battery life. Do you know how many miles you had ridden before it started doing this? Its either that or one of the cells in your battery is bad and is making the board shut off early.
Well, it started affecting riding, so I sent a message to support:
My problems started at around 20 miles. The problem was a creaking noise. It happened spontaneously and with no reasonable associated cause other than it seemed more likely when weighting/turning on one side of the board.
The sounds were definitely coming from inside the hub.
I read about similar issues and had the exact same symptoms as others on the forum.
I decided to wait as it seemed to be common enough and some were reporting the sound to go away and that it did not seem to affect the performance.
But now I am noting another effect besides sounds at a frequency of the wheel RPM.
The power delivery is no longer smooth. It's as if for 1/8th of the time or so that it's operating under half power.
I feel this while accelerating, while going a constant speed (it can also be heard and felt both at constant speed), and is particularly noticeable when climbing.
The effect makes it harder to balance and it feels unsafe enough that I no longer feel safe riding the board.
So I thought that I would e-mail and see what you guys proposed that I do.
I have been riding about 10 to 20 miles per day for the last few days, and I am enjoying the ride very much, but I hopeful that I can get a board that does not have the issues that this board has.
I have not made any modifications to the board at all, besides removing the cardboard after taking it out of the box and changing the riding mode to Cruz and later to Mission.
I have not tried any other riding modes.
There seem to be no other issues that I am aware of.
If anyone is interested in the outcome, I'll let you know. I am not as confident riding faster as it seems to be omnipresent the problem. At the height, I did look at temps and it said the motor and battery were both under 100 degrees. 98' for one and 89' for the other, but I forgot which was which.
I guess that my thinking is that if it continues to behave this way, I'm just not satisfied with it. I am very hopeful that they aren't ALL this way and this is just NORMAL. That's my worst fear, honestly.
I want more confidence that there is going to be a consistent power delivery that I can expect to be smooth. If they are intentionally cutting power for a brief moment to "scare" me to slow down, it's working, but I don't think that's what they are doing. I think something is wrong.
It would be beautiful if FM made a swappable battery. Several fellow riders have taken their boards apart and the battery just slides into the channel. Woulda been great if it could have been designed so it could be removed / replaced without taking the entire unit apart.
@thegreck Really nothing substantial. Track /tank version(manual throttle needs more hacking), replaceable battery pack ( accomplished), total waterproof (not possible with hub motor, batterypack and controller case weakpoints are the LED light seals). Yeah I dont share my builds because it takes time to document. I was hoping their are more in -depth talk here about the controller and other internal mods.
Although I have a background in Electronics , the embedded harware/software is canned and proprietary theparts availabilty is something I heavily think about should I ever make a mistake.
ITS FIXED! So charge current+time is the factor when it comes to the battery meter being off. My scenerio:
-Ran battery down to 30%
-Used solar charger+lipo to charge at 2.5A
-Charge to 97%
-Battery dies at 16%
-charge with ultra charger to 100%
-battery stays at 100% till usage drops below 25%
-running battery to dry and then charging with ultra charger does not solve problem
-ran battery to dead and then charged all the way up with solar charger with Lipo at 2.5A
-becaue of the slower charge rate and longer time some how the battery meter and BMS are back in sync and percentage decreases perfectly
