hello, sorry for hijacking this thread aswell, what would be good settings for my 12s5p q30 dual 6355 170kv
motor manufacturer max current 65A link
battery is 100A peak, 75 continuous link
vesc is a dual maytech 4.12, rated 2x 50A cont. and 2x 240A burst link
settings per vesc:
motor max: 65A
motor min: -60A
battery max: 37A ?
battery min: -6A
im tryin to get the most power out of it, without impacting longevity too much
also im a bit confused about cutoff start and cutoff end, do i only set these on the master vesc ?
@Trampa thanks for the advice. I have downloaded the Vesc Tool to my phone and ordered a Bluetooth dongle. For a dual motor setup is one dongle connected to the master Vesc enough, or do I need a BT dongle on each Vesc? Also, are there any video tutorials / instruction manuals you’d recommend for using the mobile app? I’ve viewed the video on Benjamin’s page but I wasn’t sure if there were more structured / concise user instructions anywhere else?
Is completely wrong.
6A *50V = 300W braking at top speed only.
When do you need good brakes? Answer: when you are fast.
You want to have this at -25to -35A.
VESC-Tool will set it all correct for you. Simply run the wizard and you are fine.
If he’s running a 5p pack with 30q cells, wouldn’t that be 4A (rapid charge max for 30q) x 5? Meaning a min battery amp setting of -20 amps. Divided by two so -10 per VESC?
I’ve heard many run this higher, so -15 per VESC would be 150% of max. Or -20 each for 200% max setting for min batt
I’m running 2p 30q and have batt min set at -6 currently, from what information i was able to find here on it, which is 200%. And my high speed breaking is terrible. I was under the impression that running this higher would grenade my battery
We do not charge the battery from empty to full. We only create a short spike. You can also set that to minus 50A. There is no issue for the battery. You can only apply a certain brake strength anyway. Beyond that point you fly.
Thanks. So 2p 30q could I get away with Batt min -20 per VESC just fine? Currently at motor Max min 40/35 and battery 28(14 ea) max and 12 (6ea ) min
I understand it’s just burst. Any reason to be concerned with long braking downhill? Only instance really is parking garages and it’s maybe 10 seconds at full brake downhill
@Trampa, as suggested I finally got around to installing a bluetooth dongle (flipsky 2.4g v4 4), however the vesc tool phone app states that the vesc firmware is too old and as such only limited functionality is available. It also states that as I have a bootloader install I can just update the firmware using the app. When I try to update the firmware it like looks like it’s updated successfully, however it actually remains the same at ver 3.31 (I am using a flipsky vesc he 4.12).
Well, obviously your bootloader is broken and you need to follow the SWD PROG procedure.
Your Flipsky ESC probably does not have a SWD port, so you need to find the SWD pads on the PCB itself.
It’s fast and FW 3.55 onwards can have the bootloader loaded multiple times via USB. If you sort it now, you will never have the same issue again. Also you will have the convenience of smart reverse, configuration backup, data logging, HFI and many more.
It’s probably fast if you know what you’re doing It would be great to have all these features, however I am very slow at building my board and I now I’ll be even more limited on the amount of time I can devote to building (my third baby just arrive yesterday ). What is the vesc connected to in the video? Does it need to be pre programmed? If my vesc does not have a SWD port how is it connected (soldered)?
I was wondering if installing ackmaniac 3 on the vescs would be an easy way to get the Bluetooth dongle functional? or will the corrupted bootloader prevent it from uploading and potentially stop the vesc from working?
Will this harm the battery in any way. If I set my battery at 60a but set my motors at say 70…80. What will be the results. I have a 12s6p If I’m not mistaken my battery can do 90A continuously 120A bursts. Am I correct?
So if I do 60 battery and 80 motor ( my motors are rated for 80) when I first start off my motor can pull up to 80… the faster and longer I go it will slowly be reduced until…
What cells? 30 q? If so you are good for 120amps continuous. Never exceed this.
Those cells run fine at 20 amps a piece.
Look at your motor specs and set to the limit or below.
If you want some off the line grunt then the motor amps will provide that.
If you want some grunt further up the curve then battery amps will provide this.
I always max out my battery because why not and then adjust my motor amps until they run hot to touch after a hard ride without leaving skin on the cans. Its a lot to do with riding style and environment.
