We've spent over 30 years engineering unique solutions to challenging restoration projects. In 2020 we expanded our business to include repairing 2012 Fisker Karma batteries. And with access to over $100k in battery parts inventory, we are on our way to becoming the #1 Fisker Karma battery repair facility and battery parts supplier in the world.

You no longer need to replace your entire HV battery pack!

We specialize in repairing Fisker Karma high voltage battery packs by engaging with Fisker, Karma, A123 and LiPo battery experts to develop our proprietary BenchBalance(TM) process. As a result, you now have multiple options. We can replace failed parts, recondition poor performing modules, completely balance every cell and back it with a 1yr parts warranty*.

  • 4Q2021: GREAT NEWS! We just purchased the last remaining Fisker OEM battery pack inventory from Karma! These are NOS (New Old Stock) and many of them in factory dated crates 2018-2020. These packs came from their final California inventory as they discontinued servicing 2012 Fisker and 2018 Karma Revero batteries 2Q2021. Our extensive inventory includes certified HV packs, certified individual modules and a multitude of battery parts. Contact us below for a quote.

  • 3Q2021: We recently completed another HV Fisker Karma Battery Pack repair. This included reconditioning 14 Fisker Karma Battery modules and replacing 1 module. In addition, we replaced all 3 contactors, including the dreaded #5! The cells inside each of the 15 Fisker Battery modules were bench balanced, software flashed to the MBBs and a new OBCM was included in this rebuild. The battery fuel gauge reads just like new at 50 miles of battery power!

Battery Pack Replacement
