When it comes to broken batteries, the hardest part of the repair is diagnostics and troubleshooting. At Royer Batteries, we are the premier experts of battery diagnostics and testing. Repair is possible for the lithium batteries from just about any PEV. The most common issues include not taking a charge, much shorter range, no power lights, and no power. All of which can be traced to either the cells having an issue or the onboard circuity (battery management system – BMS) failing. Performing testing can indicate where the battery is in it’s life cycle. If you would like to bring your battery back to life or have any questions, please contact us anytime.
