A cable light includes a battery receptacle that is electrically coupled to a first light module and a second light module. The battery receptacle includes a battery port that receives and retains a battery, such as a power tool battery pack. The first light module and the second light module each include a housing supporting a lens, a light emitter such as an LED, a reflector, and a hanger to hang the light modules on a workpiece. The first light module is electrically coupled to the battery receptacle, and the second light module is electrically coupled to the battery receptacle via a connection with the first light module. The battery receptacle communicates electrical power from the battery pack to the light modules to power the light emitters.

The present invention discloses an arc-shaped battery box structure for light-fixture, comprising an arc-shaped box body provided with a battery compartment and a battery cover covering the battery compartment in a matching and sealing manner, wherein, the battery cover and the battery compartment are in the shape of an elongated arc and matched with each other; an end portion of the battery cover is inclined and bent towards the battery compartment, or an open end portion of the battery compartment is inclined and bent towards the battery cover, or the end portion of the battery cover and the open end portion of the battery compartment are inclined and bent towards each other; and the battery cover and the battery compartment are quickly interlocked at an arc-shaped side wall.

A battery-powered motor may include an electric motor, a controller, and a housing. The electric motor may be wound to enable the battery-powered motor to achieve a non-limited motor maximum motor revolutions per minute (RPM) for at least one specified battery. The controlling current may include limiting current to the electric motor at lower RPMs, and limiting the current to prevent the RPM of the electric motor from exceeding a limited maximum motor RPM which is lower than the non-limited motor maximum RPM. The housing may enclose the electric motor and the controller and the specified battery. The housing may have a form factor to engage with a machine that engages with an internal combustion engine that has a maximum engine RPM that is approximately the same as the limited maximum motor RPM.

A secondary battery module includes a plurality of battery blocks each obtained by stacking a plurality of battery cells. The secondary battery module includes a holding member adapted to hold the plurality of battery blocks and including a pair of opposed end plates, a pair of opposed side plates, and a section plate arranged between the adjacent battery blocks to partition the battery blocks; and an inter-block bus bar provided across the section plate and adapted to electrically connect the adjacent battery blocks. The inter-block bus bar has a fuse portion.

A battery module prevents heat transfer between cell module assemblies in the battery module and includes a plurality of cell module assemblies and module plates. Each of the cell module assemblies includes a plurality of battery cells and an individual housing configured to receive the plurality of battery cells, the individual housing includes an upper plate located at the upper part of the plurality of battery cells, a lower plate located at the lower part of the plurality of battery cells, and two side plates located at opposite side surfaces of the plurality of battery cells, the two side plates being configured to connect the upper plate and the lower plate to each other, excluding a front and a rear of the plurality of battery cells, from which electrode leads protrude.

A vehicle battery assembly having specialized fasteners that includes an integrated compression limiter. The compression limiter provides protection for the fastening joint of a cover and a tray of a housing for the battery assembly. The battery assembly may also include nut and bolt assembly which may be installed by a nut insertion tool. The nut insertion tool allows the nut and bolt assembly to be installed without damaging the tray or the cover.

A battery module and a method of assembling the battery module are provided. The battery module includes a cooling surface having a first area and a second area with different cooling capacities, an adhesive including a first component having a first thermal conductivity and a second component having a second thermal conductivity, and a first battery and a second battery. The first battery is secured to the first area by a first portion of the adhesive and the second battery is secured to the second area by a second portion the adhesive. The first portion of the adhesive has a first ratio of the first component to the second component and the second portion of the adhesive has a second ratio of the first component to the second component. The first and second ratios are different and compensate for the different cooling capacities of the first and second areas.

A battery mounting structure for a vehicle, includes: a mounting bush provided to penetrate a portion of a battery case and including a fastening screw formed on an upper inner circumferential surface of the mounting bush; a hollow bolt coupled to the battery case and the fastening screw from above the battery case; a fastening bolt provided to penetrate inside of the mounting bush and inside of the hollow bolt up and down; and a sleeve assembly provided to guide the fastening bolt and elastically restricting separation of the fastening bolt from the mounting bush.
