Exhibit 10.1

LINE OF CREDIT AGREEMENT

This Line of Credit Agreement (this “Agreement”), dated as of December 29, 2008, is made by and between ENER1 GROUP, INC., a Florida corporation (“Lender”), and ENER1, INC., a Florida corporation (“Borrower”).

In consideration of the mutual covenants and agreements contained herein, the parties agree as follows:

1. LINE OF CREDIT. Lender hereby agrees to establish a line of credit (the “Credit Line”) for Borrower in the aggregate principal amount of Thirty Million United States Dollars (US$30,000,000) (the “Credit Limit”), subject to adjustment as set forth in this Agreement.

2. CREDIT LINE DOCUMENTATION. All sums advanced pursuant to the Credit Line (each, an “Advance”) shall be documented by Lender in Schedule I to this Agreement.

3. ADVANCES. Borrower may request an Advance at any time during the Draw Period in minimum increments of Five Hundred Thousand United States Dollars (US$500,000) (or, if less, the remaining balance of the Credit Line); provided, however, that in no event shall Borrower be entitled to receive Advances that, in the aggregate, when added to the amount of all previous Advances then outstanding, exceed (i) prior to March 31, 2009, Ten Million United States Dollars (US$10,000,000) and (ii) following March 31, 2009, the Credit Limit. Borrower shall make requests for Advances by delivering to Lender a written notice thereof specifying the amount of the requested Advance (a “Draw Notice”). On or before the fifth (5^th) Business Day following the receipt by Lender of a Draw Notice, Lender shall issue instructions for the delivery, by wire transfer to an account specified by Borrower in such Draw Notice, of the amount of the Advance set forth in such notice. Lender may refuse to make a requested Advance if (a) such Advance would exceed the Credit Limit as described above, or (b) an Event of Default occurs and is outstanding. Borrower may not submit a Draw Notice to Lender more than once during any period of fourteen (14) consecutive calendar days.

4. INTEREST. All funds advanced pursuant to this Agreement shall bear simple interest from the date on which each Advance is made until it is paid in full at a rate of eight percent (8%) per year, such year to consist, for the purpose of calculating such interest, of 360 days.

5. REPAYMENT. Borrower shall repay to Lender the entire outstanding principal of and all unpaid interest accrued on the Credit Line on the earlier to occur of (i) the fifth (5^th) Business Day following the completion by Ener1, Inc. of an underwritten public equity offering and (ii) the eighteen (18) month anniversary of the date on which the first Advance is made hereunder (the “Repayment Date”) or, if any such date is not a Business Day, on the next succeeding Business Day. All payments received hereunder shall be applied, first, to any costs or expenses incurred by Lender in collecting such payment or to any other unpaid charges or expenses due hereunder; second, to accrued interest; and third, to principal. Borrower may prepay its indebtedness hereunder at any time without penalty, in which case Lender shall record the amount of each such prepayment by appropriately annotating Schedule I to this Agreement.

6. USE OF FUNDS. Borrower will use the funds it receives pursuant to each Advance exclusively to fund expenses (including capital expenditures) incurred in connection with its operations and those of its subsidiaries.

7. OTHER OBLIGATIONS OF THE BORROWER. Borrower shall be obligated to Lender as follows until Borrower has performed all of its obligations to Lender under this Agreement:

(i) To provide Lender with a written notification of any Event of Default immediately upon learning of it; and

(ii) To timely inform Lender of any circumstances that may substantially affect any substantial increase in the obligations of Borrower.

8. REPRESENTATIONS AND WARRANTIES. In order to induce Lender to enter into this Agreement and to make Advances on the terms specified herein, Borrower represents and warrants to Lender as follows:

(ii) Borrower has the authority and power to execute and deliver this Agreement and to perform any condition or obligation imposed under the terms hereof or thereof.

(iii) The execution, delivery and performance of this Agreement by Borrower will not violate any provision of any applicable law, regulation, order, judgment, decree, charter document, indenture, contract, agreement, or other undertaking to which Borrower is a party, or which is binding on Borrower or its assets, and will not result in the creation or imposition of a lien on any of its assets.

9. EVENTS OF DEFAULT. The occurrence of any of the following shall constitute an “Event of Default” under this Agreement:

(i) Voluntary Bankruptcy or Insolvency Proceedings. Borrower shall (a) apply for or consent to the appointment of a receiver, trustee, liquidator, or custodian of itself or of all or a substantial part of its property, (b) admit in writing its inability to pay its debts generally as they mature, (c) make a general assignment for the benefit of any of its creditors, (d) be dissolved or liquidated in full or in part, (e) commence a voluntary case or other proceeding seeking liquidation, reorganization or other relief with respect to itself or its debts under any bankruptcy, insolvency, or other similar law now or hereafter in effect or consent to any such relief or to the appointment of or taking possession of its property by any official in an involuntary case or other proceeding commenced against it, or (f) take any action for the purpose of effecting any of the foregoing.

(ii) Involuntary Bankruptcy or Insolvency Proceedings. Borrower seeks the appointment of a receiver, trustee, liquidator, or custodian of Borrower or of all or a substantial part of the property thereof, or an involuntary case or other proceedings seeking liquidation, reorganization, or other relief with respect to Borrower or the debts thereof under any bankruptcy, insolvency, or other similar law or hereafter in effect shall be commenced and an order for relief entered or such proceeding shall not be dismissed or discharged within sixty (60) days of commencement.
