Roger over at LensRentals posted a public service announcement yesterday entitled "Only You can Prevent Movi Fires."
In the post, Roger explains that when the battery cables are left connected to the battery, the copper tips may come into contact with one other and cause a fire.
How common is the issue? Well, the rental house documented three fires before figuring out a solution to the problem.
And their solution is as simple as it is effective. If you own a Movi (or plan to rent one in the near future), be sure to check out Roger's post.
