Hey everyone! I'm working on a project where I want to use a 1kw 52V hub motor for an e-bike. I'm planning to control it with an Odesc 4.2 controller that can handle up to 56V, but I'm struggling to find a power supply that delivers the right voltage and wattage. I've seen a lot of options for 48V and 60V, but I can't find a reliable 52V supply. One thought I had was to use a 60V power supply along with a variable power module from AliExpress for development, but that feels a bit wasteful for my final setup. Are there any cost-effective power supply alternatives I could consider, or should I look for a different motor instead? Also, how do I assess the quality of power supplies from places like Amazon and AliExpress since most seem to be generic brands? Thanks in advance for your help!

I can't recommend a specific motor power supply, but I've had decent luck shopping on AliExpress. Just be diligent about reading specs and user reviews before buying, as some products can be real hits or misses.
I’d recommend just going with a 48V power supply; they’re way more accessible. You can sometimes find models that let you adjust the output voltage a bit higher, which could work out for your needs!
I started using step-down converters from larger 12V supplies, and it’s been a game changer. Having a power reserve is super helpful. If you go that route, consider looking for converters that are well-reviewed or even making your own if you’re handy with electronics!
Do you buy off-the-shelf converters or make your own? Any tips for what to look for when purchasing them?
