I plan to directly supply the Jetson Orin Nano from this battery for a drone project. The maximum continuous discharge current is 20 amps and the maximum peak pulse current is 40 amps (2 sec). The battery should output a steady voltage (12 V), although I did acquire it secondhand. Is a BEC necessary?
Thank you.
I don’t know the specific voltage range of this particular Jetson product, but all Jetsons are somewhat sensitive to power supply regulation quality. You definitely don’t want to run one directly off of an unregulated battery. If you did, then it would probably be unstable and either shut down or reboot unexpectedly. If you have something else loading that battery as well, then you can expect nearly constant problems. Inductive loads on that battery could even damage the Jetson (for example, motors on a drone of some sort).
Thanks for the quick reply.
From what I’ve seen, the voltage range is 7-20 V for this Jetson. I’m fairly certain that the 12 V battery voltage will be steady the whole time, but I’m not 100%, since I got the battery secondhand. Sounds like I’m better off getting a voltage regulator anyways.
Thank you.
Most of the Jetsons come with power adapters running at 19.6V, and with a max of 20.0V. However, there are some which are intended to run at 5V (maybe a 6.25V max?? not sure), and so I won’t answer on specific voltages. I can tell you that all of them need stable power (more stable than the typical micro-controller). What people consider stable may not apply when you are looking at square wave rise times in the nanosecond neighborhood.
A lot of people do use a battery, this is one reason people use Jetsons: Lower total power requirement for the amount of performance. Those who build drones and robots and power the servos with the same battery that supplies the Jetson tend to find out the hard way that regulation is an issue. Batteries are not an issue if they have good regulators on them; the same is true of ordinary power supplies: You can’t use a plug-in power supply if it has low quality regulation and/or noise filtering.
