Hello, I have problem at MINI with xl-320 ID11 : Input voltage error. It is much more bigger as is possibility. I have spare xl-320 If need, but there is no ID, and I dont know what have to do for communication with others at MINI. I hope you can help me.

Hi Marian,

ROBOTIS MINI should be used with two LB-040 batteries.

This is because recommended input voltage for XL-320 is 7.4 V.

It seems like you are using too high input voltage for the robot which can damage the electronic components including XL-320.

Please use recommended power source for ROBOTIS products.

Thank you.

I am using LB-041 which I got with my robot.. It should be the same or I must using only LB-040?

Hi, LB-041 is fine as well. If you were using two of them, the sum of voltage should not exceed 8.4V
Were you using some other power source other than these batteries?

As long as you are using two batteries(LB-040 or LB-041) in the proper location, you should be good.
If you move the battery to other location, it may affect to the robot's center of gravity and make it difficult to walk or move.
If you are getting Input Voltage Error when you are using two LB batteries, please stop using batteries and let me know immediately.
Thank you.

I guess its pointing to the wall supply as the culprit or the battery itself. I suppose its more likely i damaged the battery, but if so, why does the charger fault even with no battery connected? Maybe i damaged the wall supply? I should probably go and try to charge the battery with the car battery and see how far it gets along.

The LB-040 or LB-041 is supposed to be charged via USB port
The battery will be damaged if you try to charge with car battery as it supplies too high voltage.
Please do not use other power source than USB when charging LB-040 or LB-041 battery.
