We've spent over 30 years engineering unique solutions to challenging restoration projects. In 2020 we expanded our business to specialize in repairing 2012 Fisker Karma batteries. And with access to over $300k in battery parts inventory, we are becoming the #1 Fisker Karma battery parts and repair facility in the world.

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

We have an extensive database of OEM technical literature, specialized PRODIS diagnostic computers, tooling, and OEM inventory to diagnose and repair any Fisker Karma charging issue.

In addition, we've worked with A123, Fisker Automotive, Karma Inc, and LiPo battery experts to develop our testing, BenchBalancing(TM) and certification process that exceeds factory specifications.

We replace failed parts, properly balance every module and back it with a 1yr parts warranty*.

We offer multiple solutions: individual parts for those DIY technicians; complete battery packs for your favorite shop to install; or send us your Fisker for a complete repair.

Our flexible repair solutions are designed to meet your needs: from simple contactors and battery modules to complete replacement packs.

Our custom shop remains reasonably priced... All the expertise without the overhead... Please contact our sales department for a free quote.

  • 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
