Clipper Recommendations?

Hello everyone, I’ve been looking into upgrading my equipment but not even sure where to start. I’ve used cordless and with cord but a little iffy on the cordless ones. I had a black cordless designer Wahl clipper and hateddd how low the battery felt, it almost felt like it was going to die on me anytime lol. Have babyliss and love how clean that cuts but for some reason it’s given me a problem when it comes to really thick hair. It will pull even if I’ve oiled them 😬 so I just use it for bald fades mainly. Any clippers I should look into instead?
