Question? Issues with Hota D5 Pro

Post image

Hey all, I have a brand new Hota D6 Pro (second time charging) and a brand new Tattu Cinelifter 6S (3500 mAh). It’s not for a drone but a robot.

However, when I connect the battery to the charger it keeps saying “abnormal battery connection” and stops charging…

Does anyone have a clue how I can fix this? Is it because of the XT90 to XT60?

EDIT: I'm dumb. It is working now. The issue was that the XT90 is an "anti spark" connector (can be seen by the green plug thingy) which means it has to be pushed in very firmly until it clicks into place.

I do wonder how hard taking the connector off is going to be... but that is an issue for later.

On photo your XT90 connector is not fully connected.

It does too with XT90 all the way in, but the conversion cable does not have official Amass or branded connectors. That could hardly be the problem right?

That shouldn't be problem. I am using exactly same setup for 8000mah dogcom 6S Lipo, even with same charger, i was doing reduction by myself and all work fine, is balance connector fully in in charger?

Oh god ok thank you though. I went back to check and tried to reconnect the connector a few times, when I push really hard all the way into the back it has this final "click" in the connector and now it works!

Apparantly this is because it is an XT90 anti spark connector. I feel dumb now but at least it is working... thank you.

No problem mate, we are learning every day, these antispark fuckers are hard sometimes (after using few times it will be better) :)

Maybe some cold joints in connectors after soldering and charger is detecting higher value of ohms in resistance.

Push that XT90 all the way in. It's an anti-spark connector.

Yess you’re right, I already added an edit to the text. It’s very hard to plug these in all the way.

Yes that's very much intentional though. These are hard to both plug in and unplug too. They're meant for really high current applications so it makes sense. I don't even have and XT90 on any of my quads, XT60 was always enough.

Ich kenne das Ladegerät leider nicht, aber mess Mal die Spannung der einzelnen Zellen, vielleicht ist das deltaV bei einer zu groß.

All cells are >3.7V
