Why Tennessee customers mail in battery bms repair / reset

Tennessee has roughly 5.6 million registered vehicles, and trucks, SUVs & imports make up much of what Nashville-area shops and owners mail us. Battery BMS Repair / Reset is a bench job most Nashville shops don't keep equipment for, so owners and trade shops across Tennessee ship it to a specialist. Cross-region northeast — about 2 days each way.

Tennessee FAQ

Common questions from customers shipping from Tennessee.

Do you accept battery bms repair / reset modules from Tennessee?
Yes — we receive modules from Nashville, Memphis, Knoxville, Chattanooga and the rest of Tennessee regularly. With about 5.6 million registered vehicles statewide, trucks, SUVs & imports are the bulk of what we see from Tennessee.
Is there a battery bms repair / reset shop in Nashville I should use instead?
Most Nashville shops don't keep the bench equipment for battery bms repair / reset — they'd forward the module to a specialist anyway, which adds a markup and a middleman. Going direct to us is usually faster and cheaper. Cross-region northeast — about 2 days each way.
Does Tennessee vehicle inspection or emissions testing affect this service?
Tennessee discontinued its county emissions testing programs and has no statewide periodic safety inspection. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all Tennessee and federal requirements.
Is this a new battery?
No. This is a repair and reset of the BMS electronics inside your existing battery, not a new cell pack. When the board is the problem — which is common — repairing it restores the whole battery at a fraction of a full replacement. When the cells themselves are dead, only a new battery fixes that, and we'll tell you honestly if that's your situation.
My Porsche lithium battery won't charge — can you fix it?
Frequently, yes. On the lightweight lithium battery, a failed BMS board is a common reason the battery goes dead, won't accept a charge, or the car won't wake up — while the cells are still fine. We repair the board at component level and reset the BMS so the pack communicates and charges again. Send us the label photo and symptoms and we'll confirm before you ship.
