one question: Is it possible to remove the internal batteries but just use external battery? I have been connecting the external battery to the charging port and working well. I wonder how I can remove the internal ones to save some weight.

[@EdwardInTX]

this is what I did on one of my machines th-cam.com/video/fr1IzLPixic/w-d-xo.html

[@megallenrodriguez186]

How did you change the battery connectors? I have that issue too

[@EdwardInTX]

I used a wire stripper to pull the old ones off, and crimp the new ones on

[@Clouti451]

⁠@@EdwardInTXit may be easier to just buy an F2 to F1 converter instead of changing the connector

[@EdwardInTX]

@@Clouti451 also true

[@piermariolimena9207]

Grazie mille veramente utile Edward bravissimo e grazie

[@stefansipl6736]

Great! Thank you!

[@paradoxical9926]

Hi. May I ask why the machine can work when plugged in with a charger, but has no response when using only the battery? The seller said it's a new replaced battery from last week.

[@EdwardInTX]

The battery may have low voltage / weak health. It's possible that the battery they bought was bad. Check the voltage.

[@domg1234]

Any suggestion if ball feeder is not powering?

[@EdwardInTX]

check voltage to feeder motor, usually should be a loose wire or the board may have an issue

[@domg1234]

Thanks. Will check that, if board has an issue is it pretty much end of life?

[@EdwardInTX]

@@domg1234 yeah although you could ask [e-mail] about the parts

[@alinthemind]

Worth upgrading to lithium battery and charger.

[@stefansipl6736]

Is this possible? Do newer machines already have that update?

[@PaulJakob]

Have you done that upgrade? I’m so curious how to do that.
