Charger 1 lights stay on after disconnecting from power bank

I do not have a smart vehicle. Or hybrid. I do not have the arm update. Where or how can i either send this item back for a refund or even pay me the cost to have a hill switch installed by a reputable shop. This thing killed my car battery when i was home for 2 days this past weekend. I need the update or something else. This thing is not shutting down and its wild af.

Hi @Jleep2017, regarding this issue, we have pushed the new firmware to all users in batches.
Could you please confirm again that you have correctly registered and bound Charger 1 to your Bluetti app?
Please ensure you’re connected via Bluetooth, then update to the latest ARM version—this should resolve the problem.
