Guy in the imgur said that happened after overload error and this happened after he replaced battery, giving just the benefit of the doubt that overload might have damaged the unit already. Also if anyone planning to open, I would reach out supplier rather than breaking any possible warranty. But also home safety no joke, so there is that. I got 2 x 1300, I really liked , its been half year, only the having possibility of battery leak scared the .hit out of me because new units has new iron burn smell. It goes away after few weeks.
