Abstract: A battery management system for use in multi-battery and/or multi-cell applications, including a wiring harness for connecting a plurality of batteries in an order having at least two end positions and at least one interior position, with each position being initially occupied by one of the batteries, and an interconnection mechanism connected to the harness and configured to modify the positions occupied by the batteries. The mechanism may be configured to measure a voltage of each battery and modify the positions when a voltage difference is detected. Alternatively, the mechanism may be configured to modify the positions each time a voltage drop is detected. The order may further comprise at least one out-of-service position, with the mechanism being configured to modify the positions such that the battery in the out-of-service position and at least one of the batteries in one of the end positions are reconnected to exchange positions.

Abstract: A portable ice fishing shelter includes an integral, molded shell having a bottom wall, side and rear walls which extend upwardly from the peripheral edges of the bottom wall, and a top wall which extends between the upper edges of the side and rear walls. The shell is adapted to stand on the bottom wall in an upright position of use and has sliding surfaces on outward projections on the rear wall which can slidably support the shell on ice and snow to facilitate transport thereof. A seat is provided within the shell and compartments are provided between the seat and bottom wall for holding items such as fishing tackle, a lantern, and fish which have been caught. An optional snow blind includes two vertical panels, each having an edge pivotally supported on a front edge of a respective side wall.
