Thank you! Thank you! I just finished building my first eboard and it worked the first time I tried. Got most of my kit from you and I looks great! It's because of videos like these that really helped me along the way. And now that it's working. I wanna add some accessories, like power switch and battery display. So these videos came out just in time!! Also you have pretty good prices and really good quality stuff (10s battery is sweet), so I'm probably ordering from you. Thanks again!!
I would like to upgrade my charger for the drill battery. I know there a already ones that comes with that display but I don't want to buy a completely new one, instead I want to do it myself (also to learn more about this) Would be nice if you could make a video about this. For reference, I'm trying to to it on an makita dc18rc charger
Mike check out the diy esk8 builders build they used your 12s4 battery pack with the raptor hub motors. It’s a cool build and your battery looks good 👍🏻
I have a very similar screen but I have a problem. When the screen shows 50% is when the skate is about to run out of battery, and 50% to 0% goes down in seconds. It is well configured. Any solution?
2 questions: -Which hub motor is the best and which esc or Vesc should I use for them? -and are electric skateboards dead or why are almost all vids from 1-2 years ago? Nice vid tho
Electric skateboards are actually more popular than ever. Videos have been slow to come out as we’ve been ramping up and focusing on shipping. We’ve got an intense video production scheduled coming very soon 👍🏻
My scooter desply is LCD one my schooter battery is 72 v lithium iorn battery. But the batery level always high level. It dosent go down. The problem is wen the desply power up with externel power supply acoording to battery sos level its level is go down when i reduce the voltage. 72V to 64 and 64 to 58 V 58 to 54 V , then shows the level. But the problem is the the lithium iorn bttery alway show his sos cell volatage as 64 it will newer go down konwo. How can i get battry level for my desplay?
What are the dimensions for this indicator? I am trying to CAD out my build before I assemble so adding general dimensions for components (or ideally STEP files) really helps to know that nothing will interfere.
Those numbers seem maybe reversed? Kilovolts can vary widely between hub or direct drive motors and motors used to turn the drive wheels in a belt drive setup because they correlate to the how many RPMs the motor will turn per Kv it's receiving from the battery. You also need to know how many amps your motor is rated to handle. Certain motors are rated to be able to handle different amounts of current/amps sent through the ESC to the motors. So when evaluating a motor based on its wattage & KV rating also look at how many amps the motor is rated for. If the motor is only rated to handle 20 amps and your battery can push 60 amps of continuous discharge current you would have to limit the amount of current you push through the electric speed controller /ESC to 20A ir below to avoid overheating it & or burning it out. Assuming this would be for a belt drive setup. For motors used in belt drive setups you will typically see Watts in ranges from 1000-4500 watt per motor...with most between 1500W and 3500W. For belt drive Kv #s you will use 100kv-190Kv motors with most being between 140 & 190kv. Remember kv's relate directly to RPMs of your motor. So for direct drive setup or a hub motor setup you'll see motors with lower Kv numbers/values. When using Hub motors & direct drive motors to turn the drive wheel(s) for everyone rotation of the motor the tire attached to it also makes one full rotation which is different than motors used for a belt drive setup where the motor & its drive shaft has to make multiple revolutions to get the tire that's touching the road to complete one full rotation. I've just started learning about this stuff in the last six months or so and so someone else may have a better understanding of how you might make a motor with those values work but it doesn't sound like a motor you would typically use for an electric skateboard. But would love to hear and understand how if someone else has a better understanding of this than I do. I still have a lot to learn.
I tap into the main positive and negative leads of my battery. Might even wire up a simple switch to turn the screen on and off independently of the ESC.
How do I prevent massive voltage drop (-0.8V) when I run this meter along with a 2m 12V LED strip (60LED's p/m) light and a power source e.g: 12.6V Lithium Ion Battery (18650) 3S2P. All I want is an accurate battery capacity reading that is true to the battery and not have this reading affected by the LED strip lights.
