Does that not count?
Or is the end goal to just make a safer system run at higher volts and not go way faster?

If you run higher voltage you run lower KV to get to the same output RPM (this is how itās done in the quad world 5" quads are either 4S and 2300-2600kv motors or 6S and around 1800kv motors).
Hmmm interesting point of data. Thank you for that.
higher voltage and lower kv is mostly equivalent to higher voltage & increasing the gear reduction, but slightly less efficient, because a higher kv geared to the same top speed is more efficient than a lower kv motor geared to the same top speed and the same km (size constant).
*up to a point based on iron losses with very high kv motors
@wafflejock @Venom121212 itās even conceivable higher voltage could be less efficient with the same settings and same gear ratio, because suppose you are accelerating full throttle, and you have 60a motor limit and 30a battery limit, and you are at a speed where you are hitting the battery limit, a higher voltage will result in higher motor current, increasing the acceleration but reducing the efficiency.
More voltage for more speed using the motors that are available now; without changing the gearing or the torque.
I figure this is an appropriate place to ask this question instead of a new thread.
1: Can ABS over current faults be caused by lack of enough capacitance near the ESCs, and can it be effectively solved by adding more caps close to the ESCs?
2: If adding additional caps, does the length of wires coming from the cap bank matter or not, as long as the wires are connected as close to the ESCs as possible?
Iām asking to gather more first hand experience. in my personal experience, Iāve noticed a hefty cap bank comprising different sized over rated capacitors eliminates all my faults and weirdness when running long and mismatched length battery wires. Now that Iām working on extending my battery wires even more, but still getting faults as is, I see it as a necessity to reinstall my cap bank⦠but Iād like some flexibility with where it goes.
I can answer the second question: Yes, the length of wire matters very much. The point of adding capacitance is to counteract the inductance of long wires. If you add long wires to your capacitors, youāre removing the only beneficial effect the capacitors have.
Even a couple inches can affect things in high-ripple situations.
I just finished a diy build and went out for a test ride and when i pushed on the accelerator, it felt like nothing happend. Then i pushed to full throttle, i saw it was speeding up a little but felt like there was no torque at all. My build has a focbox unity, metroboard 10s8p battery, backfire g2t hub motors, and flipsky vx1 remote. I assume something is wrong because even my backfire g2t stock has way more torque although its a low power hub board. Any idea why theres almost no torque? I can provide the setup i have in the focbox software and a video showing it doesnt not accelerate much when i push full throttle on the remote. I dont know if u need a different software setup for hubs motors vs belt motors, so i just matched volts, amps, and remote setup to my build, i didnt change any rpm stuff or advanced remote config. Any help or suggestions please would be very much appreciated. Thanks!
Asking the obvious questions, but did you change the setup from the default? Or did you just click through it while configuring?
You gotta give us something to work with. Pics, screenshots, verbal descriptions of the relevant settings, smoke signals, SOMTHING.
Hereās a quick rundown of the most common things that can be set wrong that might cause those symptoms:
Remote: Did you set the max. and min. signals correctly? How about deadband/midpoint?
Voltage: What do you have your low voltage cutoffs set to? They should start at ~33 and end at ~30.
Current: What is your battery current set to? Should be at least 20A. What is your motor current set to? Should be at least 30A, or the rating of your motors.
Battery: Is your battery charged? What is your battery voltage?
Loop key (if installed): Is the loop key pushed all the way in?
Did you calibrate your throttle on your remote?
Hi looking for some help on thermistors for batry temp sensors
I need a 100kOhm NTC Thermistor but know nothing about them been doing some poking around the internet and found out you can get different types disk, barel, capsular, glass bead, Thin Film
Can any one enlighten me on any good ones or things to avoid
I think this might be the easiest to install on the battry but unsure on any thing else about it
Thanks for any advise in advance
Do u want a picture of the tool while the focbox is connected to everything? Im current running a temporary setup with the backfire esc but i remember the values i put in the focbox.
Just to answer some of ur questions for now.
Used PPM on remtoe and did calibrate.
Battery: 27 amps discharge, -8 regen
Motor current: max motor 8 amps and max brake -8 amp (i contacted backfire and they said 10 amps max per motor)
Battery is charged around 40v i think and i used power switch not loop key.
Reallyā¦
Youāre already not very well liked with a few of people on here and now you want to start s*** like this.
Bitch Iāll blind you with eagle piss and shit down your throat.
Speaking as a Canadian, theyāre not all that bad.
Sometimes one or two individuals give them a bad rap but in my experience most Americans are good, honest folk. Just be nice with them and theyāll return the favour.
Iām honestly not a big fan of at least half of my American counterparts.
But I could probably say that about any and every country in all honesty. People in general suck.
What I donāt like is people making broad statements about an entire country. Especially on a forum such as this where we have international members from pretty much everywhere.
Thereās a reason we donāt bring up Politics on here.
Wait, so individuals of a nation arenāt represented by others in that nation? I can be⦠Myself?
Fwiw all Canadians I have ever met have been lovely folks. I take it that means youāre alright too.
Whoa⦠Itās almost like people are unique individuals and you canāt categorize them by geographyā¦
I like to think Iām alright, at least. I just try to be honest and friendly regardless of who Iām talking to
