A battery pack comprising a frame and two or more battery cells installed to the frame. The two or more battery cells are interconnected by a rotatable connector which is configured to enable electrical connections between the two or more battery cells. The rotatable connector is adapted to be switched between at least a first rotational position in which the two or more battery cells being electrically connected, and a second rotational position, in which the two or more battery cells being not electrically connected. When the user actuates the knob on the battery pack, the connecting terminals change their rotational positions from a non-conducting position to a conducting position, thereby enabling the electrical connections between the groups of battery cells.

Battery pack containing a rotatable connector

A battery pack containing a frame; and two or more battery cells installed to the frame. The two or more battery cells are interconnected by a configurable connector which is configured to enable electrical connections between the two or more battery cells. The configurable connector is adapted to be configured in a first status or a second status. In the first status, the two or more battery cells are electrically connected, and in the second status, the two or more battery cells are not electrically connected. The battery pack is not fully operational without the terminal holder inserted, therefore before it is delivered to the end user the energy loss due to self-discharging during storage and shipping can be minimized.

Battery packs and method of assembling battery packs

A battery pack (), which includes: a housing; a frame disposed inside the housing; and two or more cells () mounted to the frame. The two or more cells () are connected with each other through a configurable connector (). The configurable connector () is suitable to connect or disconnect an electrical connection between the two or more cells (). Wherein the configurable connector () includes a user contactable switch () located on an outer surface () of the housing. The user contactable switch () is configured to move within a plane parallel to the outer surface (), such that the contactable connector () is switched between a first state and a second state. In the first state, the electrical connection exists between the two or more cells (); in the second state, the electrical connection does not exist between the two or more cells (). Therefore, the battery pack () may disconnect a connection of the internal circuit thereof in non-use state, such as shipping and storing, such that the battery pack () can disconnect its internal circuit in the non-use state such as transportation and storage, such that the loss caused by the self-discharging may be minimized and the safety hazard may be avoided at the same time.

The present invention discloses a large-scale and multi-span breeding greenhouse for adult black soldier flies, comprising greenhouse bodies. Each greenhouse body comprises a pupae room and a mating and oviposition room; a partition wall is provided between the pupae room and the mating and oviposition room, the partition wall is provided with a door hole communicating the pupae room and the mating and oviposition room; the pupae room is opaque; the greenhouse body further comprises a light guiding device which introduces sunlight into the mating and oviposition room. The present invention provides a suitable growth and breeding environment, ensures a high reproduction rate, and can achieve large-scale captive breeding of black soldier flies. The greenhouse has a high level of automation and can be easily cleaned and maintained. Little human interference takes place in the breeding process, no random oviposition is observed, and the egg collection rate is high.
