How do I troubleshoot a massive voltage drop and power failure on my Hikiddo BDM-0906 24V ATV?

Based on the symptoms described for your Hikiddo BDM-0906 ATV, a drop from 12V to 4.7V under load (pressing the pedal) indicates a severe power delivery issue. Since the vehicle is only 2 days old, please check the following:Battery Connection: Lift the seat to access the battery compartment. Ensure the red and black terminals are pushed firmly onto the battery posts. A loose connection can show normal voltage at rest but fail immediately under the high current demand of the motors.Battery Health/Charging: The BDM-0906 is a 24V system (using two 12V batteries). If your display shows only 12V at rest, the battery is either severely undercharged or one of the two batteries is not connected/functioning. A fully charged 24V system should read significantly higher than 12V. Ensure you have charged the unit for the recommended 8-12 hours.Wiring Inspection: Check for any pinched wires near the rear axle or motor assembly that might be causing a short circuit when the motors attempt to draw power.Thermal Breaker/Fuse: If the ATV turns off and only works after a power cycle, the internal circuit breaker may be tripping due to an electrical fault or excessive load.Recommendation: Because the voltage drop is so extreme (down to 4.7V) on a brand-new unit, this often indicates a defective battery cell or a loose main bridge wire between the two 12V batteries. If tightening the connections and a full 12-hour charge do not resolve the issue, contact Hikiddo support as this likely falls under a manufacturing warranty claim.
