We had a few cases where the fuse in the Panasonic batteries (production release September 2016) got hot and melted partially. This can cause interrupted motor operations or a complete stop of operation.
How to fix:
Open the battery case by removing the 4 screws. Locate the yellow fuse – if it looks like in the picture replace it with a 30Ah standard car blade fuse. Check contact in fuse holder before and if required remove residuals from melted plastic, clean with electric contact spray. Fix fuse with cable tie.
Assemble case. Please ask us for a warranty sticker.
