Why Connecticut customers mail in battery bms repair / reset

Connecticut has roughly 2.9 million registered vehicles, and European luxury (BMW, Mercedes, Audi) make up much of what Hartford-area shops and owners mail us. Battery BMS Repair / Reset is a bench job most Hartford shops don't keep equipment for, so owners and trade shops across Connecticut ship it to a specialist. Cross-country northeast — about 3 days each way.

Do you accept battery bms repair / reset modules from Connecticut?

Is there a battery bms repair / reset shop in Hartford I should use instead?
Most Hartford 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-country northeast — about 3 days each way.
Does Connecticut vehicle inspection or emissions testing affect this service?
Connecticut requires a biennial OBD-II emissions inspection for most vehicles statewide. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all Connecticut and federal requirements.
Do you cover EV or full-hybrid traction battery packs?
No. This service is for the low-voltage lithium and 48V mild-hybrid BMS units described above. High-voltage traction battery packs on full hybrids and EVs are a different animal — different chemistry, different voltages, and real high-voltage safety requirements — and are outside this service. If you're unsure which you have, send us the details and we'll tell you.
Do I need proof of ownership for this?
No — a BMS repair isn't security or immobilizer work, so there's no proof-of-ownership gate on this service. The only thing we ask you to do first is verify your exact unit: send a photo of the battery/BMS label and your symptoms so a technician can confirm we cover it and that the fault looks like electronics rather than dead cells before you ship.
