I’m new to motors and I am trying to build a raspberry pi project. I’m interested in getting the M8325s 100KV and Odrive S1 bundle. I was wondering what kind of battery I can get to support the motor, I wasn’t sure which one would fit during my research online. Does the M8325s 100KV need a CUI encoder to function? I watched the Odrive connecting with Arduino guide and that motor had a CUI motor attached. Thank you.
Hi!

Good question! Really depends on the the maximum speed and torque you need. It’s usually easiest to just start with a power supply, we sell this one, but it’s a bit chunky – anything over 12V/60W or so should be fine to get started and testing – higher voltages and powers are really only needed for higher torques and speeds, respectively.
Does the M8325s 100KV need a CUI encoder to function?
Nope! All ODrive systems need some sort of encoder, but the M8325s + S1 kit uses the onboard magnetic encoder on the S1, makes things nice, easy, and compact 
Thank you so much for your reply! I’m trying to make a portable project, so I’m interested in a battery. I’m currently looking into a 1550mAh 6S 24v Lipo battery. Its labeled for drones and I am just concerned about how it would connect to the Odrive S1. The discharged plug is a XT 60 connector. I’m thinking maybe I can just take the connector off and plug it into the correct ports on the S1. Would that work? Thanks again.
For anything with batteries, I’d definitely recommend having some sort of connector, so you can easily disconnect the battery. And having just bare wires on a lithium battery is a bit dangerous, since if it shorts, that’s a lot of energy being discharged (could lead to an electrical fire).
I’d probably recommend getting an XT60 extension cable, then cutting that and connecting it to the S1. That way, you can easily connect/disconnect the battery.
One thing to note is that when you connect the battery, it’ll dump current into the capacitors on the S1, which can cause a pretty big spark and degrade the connectors on the battery (as well as stress the battery and S1 a bit). So I’d generally recommend using a specialty “antispark connector,” which has an additional component in the connector to prevent this (and cause a smoother startup of the current flowing into the S1 when connected). That being said, it takes a bit of soldering to connect that to the battery, which you may or may not be comfortable with. There’s also standalone antispark power switches like these.
Thank you so much for your response again, its been super helpful. I’m probably going to just get the XT60 extension cable as I’m not the most comfortable soldering the antispark connector. Does the spark happen only when the S1 is turned on before hand? I’m just a bit worried about degrading the connectors.
The spark will happen whenever you connect the battery to the S1, whether or not it’s turned on. If you’re not super comfortable soldering, I’d definitely recommend something like that antispark power switch I linked. You could also consider a busbar for easy power connection, something like this or this, which would just require some ring terminal connectors and a crimper. For quick connections, the Wago 221 is super easy and amazing (just snaps together, no soldering or crimping), but I think the wires on the antispark power switch might be a bit too thick for it (8AWG on the antispark, 12AWG max on the Wago).
