Yeti 400 Litium is dead

Options

Hello,

The weekend before last at 1.5 degrees Celsius I connected the Yeti to the solar panel for charging. After some time I wanted to check on the balcony, how far the charging status is and had to find that the Yeti steams / smokes.

It was not a burning smell. I immediately disconnected the panel from the Yeti. The display was off and the switches for the outputs were not working either.

Disconnecting the battery for more than 10 minutes did not affect the Yeti's functionality. 

After I reconnected the battery, the lid became warm after a few minutes. 

I immediately disconnected the battery from the boards again. 

I assume, without further knowledge of electronics, that the circuit board with the transformer is defective.

Are the circuit boards available for purchase individually as spare parts?

With kind regards 

Thorsten
