First time doing DIY. Would these two work? The battery and the kit. From the picture, it does seem XT60 connectors.

I don't want to go super fast or anything. 500w is more than enough.

500w and 36v. Front wheel, 26c size.
And the battery is this.

The option where it's XT60 + DC. It says 100ah, but I think it's around 50ah anyway. Even if it's scam, that's more than enough.
Tell me, if I'm doing something wrong here.
