A hard cover for spas, hot tubs and the like has an outer layer defining one or more cover portions that may be hinged together along a common top edge. Each cover portion internally includes a plurality of rigid panels, which may be made of expanded polystyrene or another rigid foam or the like. A support structure that mechanically couples and/or supports the panels is provided to improve the load-bearing capacity of the spa cover, optionally providing sufficient strength to conform to applicable safety standards. The support structure can include beams having various cross-sections, or combinations thereof, and may be provided in multiple segments that are shorter than the overall length of the cover. A vapor barrier film can be provided that encloses the panels and optionally some or all portions of the support structure to protect these components from degradation in the spa environment.

Rigid cover for spas and hot tubs

The present invention relates to devices that may be used in conjunction with one or more battery modules and related methods. More particularly, the present invention relates to a devices and related methods allowing one to manually disconnect high voltage and high current devices from a system. In one aspect, the present invention provides a mid pack break. The mid pack break is able to manually disconnect high voltage and high current devices from a system. The mid pack break includes a handle, a pin, a first sleeve, and a second sleeve. Force exerted on the handle causes the pin to insert into the first and second sleeves, thereby completing an electrical connection between the first and second sleeves.

Devices and methods related to battery modules

An improved compact pilot-assisted pressure relief valve is disclosed. The invention includes a vent piston or the like hydraulically dividing the valve body bore into a hydraulic fluid chamber and a spring chamber which is vented to atmosphere, such that backpressure is eliminated entirely for both faster reaction to pressure impulses and improved accuracy in pre-load setting of the valve assembly.
