  • BYD Atto 3 12V Auxiliary Battery Health Check & Upgrade to Lithium 12V LFP

    BYD Atto 3 (Yuan Plus)

    A quick heads-up for fellow BYD Atto 3 owners around the 15,000 km Winter & Summer Log mark: testing and maintaining the 12V auxiliary battery located under the bonnet prevents nearly all random dashboard warning faults.

    How the Atto 3 Smart-Charges the 12V System:

    • The high-voltage Blade Battery DC-DC converter automatically tops up the 12V battery even when parked, indicated by the blue LED flashing on the dash.
    • However, if a dashcam is hardwired without a 12.4V low-voltage cutoff, it can cycle the factory lead-acid 12V battery repeatedly.

    Prevention Checklist:

    • Set hardwired dashcam parking mode cutoff to 12.4V (or 12 hours max).
    • Measure resting terminal voltage with a multimeter (healthy is 12.6V+; anything below 12.1V under load should be replaced under warranty or upgraded to a drop-in 12V LiFePO4 auxiliary battery).
