       Nature of Business
       Flux Power Holdings, Inc. (“Flux” or the  “Company”) was incorporated as Olerama, Inc. in Nevada  in 1998. Since its incorporation, there have been several name  changes, including the change in January 2010 whereby the name of  the Company was changed to Lone Pine Holdings, Inc. Following the  completion of a reverse merger on June 14, 2012, as described  below, the Company’s operations have been conducted through  its wholly owned subsidiary, Flux Power, Inc. (“Flux  Power”), a California corporation.       On May 23, 2012, by way of a merger, Lone Pine Holdings changed its  name to Flux Power Holdings, Inc. (“FPH”) a Nevada  corporation. The transaction has been reflected as a reverse merger  where FPH was the surviving legal entity after the merger. Flux  Power remained the accounting acquirer. The merger has been  accounted for as a recapitalization as of the earliest period  presented. Accordingly, the historical condensed consolidated  financial statements represented are those of Flux Power.       Flux Power develops and sells rechargeable advanced energy storage  systems. The Company has structured its business around its core  technology, “The Battery Management System”  (“BMS”). The Company’s BMS provides three  critical functions to their battery systems: cell balancing,  monitoring and error reporting. Using its proprietary management  technology, the Company is able to offer complete integrated energy  storage solutions or custom modular standalone systems to their  clients. The Company has also developed a suite of complementary  technologies and products that accompany their core products. Sales  during the twelve months ended June 30, 2013 and 2012 were  primarily to customers located throughout the United States.       As used herein, the terms “we,” “us,”  “our,” and “Company” mean Flux Power  Holdings, Inc., unless otherwise indicated. All dollar amounts  herein are in U.S. dollars unless otherwise stated.       Reverse Acquisition of Flux Power Inc.
       On June 14, 2012, we completed the acquisition of Flux Power (the  “Reverse Acquisition”) pursuant to a Securities  Exchange Agreement dated May 18, 2012 (“Exchange  Agreement”) by and among Flux Power, and its shareholders,  Mr. Christopher Anthony, Esenjay Investments, LLC, and Mr. James  Gevarges (collectively the “Flux Power Shareholders”).  In connection with the Reverse Acquisition, we purchased 100% of the issued and outstanding  shares of common stock of Flux Power from the Flux Power  Shareholders in exchange for   37,714,514 newly issued shares our common stock  (“Exchange Shares”) based on an exchange ratio of 2.9547039 (“Share Exchange  Ratio”). As a result of the Reverse Acquisition, the Flux  Power Shareholders collectively owned approximately 91% of the issued and outstanding shares  of our common stock, and Flux Power became our wholly-owned  operating subsidiary. The Reverse Acquisition was accounted  for as a recapitalization affected by a share exchange, wherein  Flux Power is considered the acquirer for accounting and financial  reporting purposes and has been reflected in the accompanying  condensed consolidated financial statements as of the earliest  period presented. The assets and liabilities of the acquired entity  have been brought forward at their book value and no goodwill has  been recognized.    |
