Hi Jim! Thank you very much for a very informative video! I have a question on over-discharging mentioned in this video. You mentioned that the NP-F battery adapter has over discharge protection @4:13 . But then at @20:14, you mentioned 'This is direct to the batteries, be careful with over discharge!' when using the same battery adapter. Are these battery adapters safe from over-discharging? Asking for clarification, as I am planning to build a Jetson Orin + multiple LiDAR setup for a mobile scanning equipment :) Thank you in advance!

[@JetsonHacks]

Thank you for the kind words. There are two ports on the adapter. The first is regulated @ 12V. The other port is 7.4V which is direct from the batteries in the pack. It's basically a 2S battery, which means you'd expect voltages from 6.4V to 8.4V depending on battery charge on the 7.4V port. Because you're coming directly off the battery, it's unlikely there's any BMS circuitry to prevent over discharge. The 12V port is most likely protected. Hope this helps, and thanks for watching!

at 4:24 you say the operating range is 9-19volts, everywhere online and including your description it says teh Jetson should run at 5volts. Can you clarify this? Thanks

[@JetsonHacks]

There are two Jetsons in the video. The Jetson Xavier NX has an operating range of 9-19V. The Jetson Nano, which is the one which uses the boost/buck converter here, operates at 5V. I hope this clarifies things. Thanks for watching!

[@boredbrainedbeing]

Thank you so much for explaining the different ways we can supply power to the jetson. I just had a question, if I use a power bank as my power supply to the Jetson nano, can I use a LIDAR and a webcam plugged into 2 USB A ports of the jetson simultaneously? Also, how long can I use the power bank? I mean, how long does it last? Also, if i can't use the lidar and webcam using power bank, then can i make a power supply using AA batteries or 9V batteries instead of buying the np-f style batttery?

[@JetsonHacks]

It depends on the lidar that you're using and the webcam. A USB port on the Jetson can supply 1 amp. If your devices draw more than that, you will need to power them externally. Also, the Jetson dev board has a maximum amount of power it can provide total to the devices on board and peripherals. The battery life depends on a variety of factors, but the most important is the power draw from the load. If you're running the Jetson without peripherals at low power modes, the battery charge will last much longer than a fully connected Jetson running high speeds. Of course, it will also depends on the size of the power bank, which can range from small to large. Building a power supply from AA batteries or 9V batteries is beyond what can be covered here in a KZbin comment. Typically people don't do this because this is a more expensive solution than using 18650 lithium battery cells which hold a lot more energy in close to the same form factor. Most people would use something like a UPS (this is one for a Jetson Nano 5V) amzn.to/3MN01Wv Also, in general you have to regulate the voltage to make sure it stays in a range compatible with the devices for which it is providing power. For example, a fully charged 9V battery is ~ 9.6V, a discharged one is ~ 7.2V.

[@puigalejandro24]

Thanks a lot! Is that car you showed for something like f1tenth?

[@JetsonHacks]

You are welcome. The car is something simila to F1/10, although it is used in research and development. The main difference is that it has a 3D lidar whereas the F1/10 has 2D. Thanks for watching!

[@Athens1992]

nice video!! One question if I want to power the jetson with 4A, with barrel can I do it with 6x 18650, like (B1+B2)//(B3+B4)//(B5+B6) and afterwards a stepdown converter to 5V?

[@JetsonHacks]

Thank you for the kind words. It's difficult to answer this question. You will need to check the batteries to check the discharge rate. There are 18650 batteries that deliver that kind of amperage, but let's just say that the vendors can be a little aggressive in their marketing claims. Unfortunately about the only way to know is to test it out. Good luck on your project, and thanks for watching!

[@sy2532]

Since the Orin Nano takes 19v... and you are saying the voltage range is between 9v - 19v then the 14.8v straight from a standard LIPO battery would be fine?

[@robust_koo]

Thanks a lot! Is there any way to know the battery's remaining power? I need to safely shut down system before battery goes down.

[@JetsonHacks]

You will need to do a little bit of work to gain that feature. If you are using the SmallRig plate shown in the video, there is a 7.4V raw output which is the output straight from the battery. There may be simpler ways to do this (or an inexpensive dedicated solution), but here's one way: Through a resistor voltage divider (usually a couple of resistors), connect an Analog to Digital Convert (ADC) to the ouput of the battery. These are pretty common, there are available in the Raspberry Pi ecosystem. For example, Adafruit offers a MCP3008 and the ADS1x15 series. The ADC should have something like an I2C or SPI to interface with the Jetson. You will need to select the proper resistors for the voltage divider. The voltage divider takes the raw input from the battery and divides it to a lower voltage range which the ADC can read. Then, you will need to monitor the ADC to check if the voltage has fallen below your desired threshold. Thanks for watching!

[@davidb7723]

How do you think this compares to use using lipo? Seems like a safer setup.

[@JetsonHacks]

For makers and people who do not professionally build LiPos into products this is a better alternative I believe. There's a lot of issues with battery charging/overcharging and not having a good battery management system built into the battery itself that this solves for most people. Because of their use in the photography/video industry, these NP-F style LiPos are much more mass market devices than the "soft cell" LiPos that you see in products like R/C vehicles. If you're designing a product and you know what you're doing, you can save weight and money building your own battery packs. However, note that even in large scale devices, like a Tesla Electric Vehicle, individual cells are still used. Early models of Teslas used the same size cell (18650) as those in the NP-F style batteries. They used a few more, of course for each vehicle. Thanks for watching!

[@davidb7723]

@@JetsonHacks Would it be better to use the 12v output on the small rig plate as it would protect the battery? It seems like without using the protected side you're running into the same situation as with LiPo batteries. At least I'm guessing it's more protected that the straight 7.4v output - I inferred from your comments in the video that it needed to be watched to prevent over discharge. Also, I've watched this video at least 3x, thanks for the excellent content. I really like the links to the products used in the video, it's really helpful.

[@davidb7723]

​@@JetsonHacks I'm concerned about weight on my vehicle as I'm using a 1/16 scale donkey car. I've got a robohat mm1 coming as well, which they suggest to hook a lipo up to and then that will run power to the jetson amd esc. This is my first RC or robot build other than my Prusa 3D printer lol. I picked up a battery alarm for lipo batteries which should alert before it drops too much voltage. I think the mAh is better with lipo, but the management stuff does seem to be a pain. However the more I think about it, it seems like the better option, I just need to be mindful.

[@JetsonHacks]

@@davidb7723 Thank you for the kind words. Yes, the 12V is regulated so that's the one that's easiest to use. Typically you would use the regulated output if you're trying to run 12V devices. If you run from the 7.4V side (unregulated) you should monitor the voltage to make sure you don't draw the battery down past it's safety point. Also, you can use the unregulated side to monitor the voltage of the battery.

[@darldlwi687]

Hi how much the current output of the battery pack? Is 4A?

[@JetsonHacks]

There are several factors. One is the discharge rate. Typically these batteries have a discharge rate of 1C or 2C. Depends on the which battery and manufacturer you are using. A C-rate is a measure of the rate at which a battery is discharged relative to its maximum capacity. A 1C rate means that the discharge current will discharge the entire battery in 1 hour. So, if the battery is 1C, the NP-F 750 style battery in the video will discharge ~ 5A, the smaller NP-F 550 will discharge ~ 3.3A. Unfortunately it is difficult to tell without testing the battery, as manufacturers tend to fib a little about such things. Thanks for watching!

[@JetsonHacks]

Wow, thank you very much for your generosity! I'll use it to make more content.

[@JJ-sp7ix]

Hi, would it be safe to use an NP-F style battery and a smallrig adapter in a circuit that powers both a jetson nano(through pins), as well as 2 12V, 3A stall current motors? The maximum current draw for such a use case would be roughly 8A (12V2A for the jetson nano, and since each motor's stall current is 3A, that adds up to 8).

[@JetsonHacks]

Hmm. The Jetson Nano is 5V, did you mean Jetson Orin Nano? Typically you would isolate the motors from the electronics, as the motors are electrically noisy. If you are using a Jetson Nano, then you will need to step down the voltage to 5V. An 8A draw is pretty taxing on this type of battery. Thanks for watching!

[@JJ-sp7ix]

@@JetsonHacks I see, I was planning to use a buck converter to fix the voltage to 5v for the jetson nano. I think I will look for other solutions to power my motors separately then, thanks!

[@JJ-sp7ix]

​@@JetsonHacksMay I know what sort of power supply you would recommend to power 2 12v3a motors? I am quite new to all this, which is why I am looking for safer options. Would a battery holder with 8 rechargeable AA batteries (8x1.2v=9.6v) be a good option? I plan on attaching that to a buck boost converter to maintain the steady 12volts for the motors.

[@JetsonHacks]

@@JJ-sp7ix If you are using 8 rechargeable AA batteries in series, they provide 9.6V, but provide < 3A of current at best. When choosing a battery to power your motors, you need to consider several factors, including voltage, current capacity, and total power requirement. Here's a step-by-step guide to help you select the right battery: Voltage Requirement: You have to supply 12V, or convert the voltage to 12V externally. Current Requirement: Each motor draws 3A. If you plan to run both motors at the same time, you will need a battery that can supply at least 6A (3A per motor). Total Power Consumption: The total power consumption of the motors can be calculated by multiplying the voltage by the total current. For your motors, this would be 12V×6A=72W. * Battery Capacity (Ah): To determine how long the battery can run your motors, you need to consider the battery's capacity in ampere-hours (Ah). For example, if you want the battery to run the motors for a specific amount of time, you can calculate the required capacity. If you need the motors to run for 1 hour, a battery with at least 6Ah is necessary. * Type of Battery: For such applications, the most common types of batteries are: Lead-Acid Batteries: These are economical and readily available but are heavy and have a lower energy density. Lithium-Ion Batteries: These provide a higher energy density and are lighter but are more expensive. They also offer higher discharge rates and longer lifespans. * Battery Configuration: If you are considering series or parallel configurations: Series Configuration: Increases voltage but keeps the current capacity the same as one battery. Parallel Configuration: Increases current capacity but keeps the voltage the same as one battery. For your case, you might consider connecting two 12V batteries in parallel to ensure there is enough current capacity without altering the voltage. * Considerations for Safety and Efficiency: Make sure to include a battery management system (BMS) for lithium-ion batteries or appropriate charging and maintenance for lead-acid batteries to ensure safety and prolong battery life. * Weight and Size: The size and the weight of the battery may be important in how you choose the battery capacity. That may be important based on your application. Based on your needs (running two 3A 12V motors), you might consider a 12V lithium-ion battery pack with a capacity of 6Ah or more, depending on how long you need the motors to run per charge. This type of battery will offer a good balance between weight, capacity, and efficiency. Make sure the battery can handle the continuous discharge rate of 6A or higher. You should consider asking in a different place if you have specific questions to help you along.

Hi sir. Great video but you have not shown how to power a 2GB Jetson Nano through GPIO pins. I want to power the Jetson Nano 2GB with a lipo battery. So by reading the docs i learned i can power it through gpio pins but does it mean that i can connect both the 5V pins at the same time?? Will it give me the maximum performance?

[@JetsonHacks]

The 5V pins are tied together, using both of them won't make a difference. Good luck on your project!

[@_DarkKnight2301_]

Hello. I have a potentially obvious answer question about powering the jetson nano 4gb. The project i have is very power hungry which causes the jetson nano to throttle itself at times. I currently have one power input through the gpio pins. Is it possible to power the jetson through two methods at the same time? So, could I power it through the gpio pins and the micro USB as well? Probably an obvious answer, but I am new to messing with hardware and don't want to break the nano.

[@JetsonHacks]

There are two 5V pins on the GPIO header to which you can supply 3A each (6A total). This is directly on the power rail, so it is not possible to provide "more power" through the other connectors; they all go to the same place.

It's available in different sizes: amzn.to/4aB4Zzh The blue mat is a silicon soldering mat, which is resistant to heat and helps keep parts from rolling away. They are available in different sizes and colors. I would stay away from the black ones, as a lot of screws and components are black. This makes them difficult to see when placed on the mat.
