Én aliról rendeltem, de vigyázz mert az olcsó kínai kondik lutrik. Van ami már új korában sem tudja a ráírt paramétereket, van amelyik fél év után megint meghibásodik.⏎

Egy pár mm -el nagyobb mint a gyári ezért a töltő belső részén egy picit faragni kell.

Hello! What brand of capacitor did you buy? Cheap Chinese was also very unstable for me. There are things that have been working for a few weeks that have been working for months.

However, there is already a machine made by Nichicon that has been in it for maybe 1 year. It is true that it is a few mm higher, so you have to file a little off the inner wall of the charger to fit it.

I took all the capacitors apart. In Chinese, the rolled material is very narrow and short. Then comes the factory one and the widest and longest one is in Nichicon.

Thanks, I found it later. That's the only way I'm afraid that the person who deals with the given topic won't see it and won't respond to it.

Hi @hainzy !

My question its moved so, i try answear here.

"the Parts your replaced where faulty, or did you replace them without checking?

when you are already replacing parts you could also try to replace these:

- Mosfet B09N03 (EMB09N03H) or B09A03 (EMB09A03HP) - depending on the version

- Controller MAX8731A (MAX8731AETI+) or BQ24773 (ref BQ24773RUYT) - depending on the version

or you replace the whole board of the Robot, or the charger.

That would probably be easier...

But you did already check the battery, right? "

The capacitator its fault , the mosfet i think not, but i have one new so i chang it.
The battery its good, with another charger allworking ok.

If i can buy, i will try change the Mosfet B09N03 and the Controller MAX8731A. Thanks,

Hi !

I have the same problem Error 13 . In the robot changed the P185 fuse.

I have 2 charger. In same chaerger changed the condensator . Not some cheap, im using Nichicon 450v 68uF.

One charger working good, all ok, but the another not.

On the bad charger measuring 4,2v , if charged 20v.

Sometimes the robot starts charging, but after a few days it doesn't. Then I put the charger aside and after a few it's good again for a while.

In the bad charger changed again another Nichicon condenstor --- not working

Cahnged the ISA07N65A Mosfet ---- not working

what can i do? Have any idea ? Thanks
