The battery replacement procedure for electric drift cars varies depending on the model and how the battery is installed, but usually follows the following general process. The following are detailed operating instructions and precautions:

I. Preparation

Confirm the battery model

Check the vehicle manual or the label on the original battery to clarify the battery specifications (e.g., voltage, capacity, interface type, etc.) and ensure that the new battery is compatible with the original vehicle.

Common battery types: Lithium-ion (Li-ion), Lead-acid (Lead-acid), and some models may use a specific type of battery pack.

Tool Preparation

Screwdriver (Phillips/Japanese screwdriver depending on the type of battery compartment screws), gloves (optional, to prevent electric shock or scratches).

Safety check

Switch off the power of the vehicle and make sure the battery is disconnected to avoid short circuit or electric shock during replacement.

Choose a dry and ventilated environment for operation, and keep away from ignition sources and flammable materials.

B. Battery Replacement Steps

1. Locate the battery compartment

Common location:

Underbody: The battery compartment of most models is located under the chassis, you need to turn over the vehicle to check.

Side / Rear: Some models are designed with a side-opening or rear-mounted battery compartment, which can be seen by lifting the cover.

Under the seat: Children's toy drift cars may hide the battery under the seat.

2. Remove the old battery

Step-by-step example:

Use a screwdriver to unscrew the retaining screws of the battery compartment cover and remove the cover.

Observe how the battery is connected:

Plug connection: Find the plug of the connection cable between the battery and the car body and pull it off gently (pay attention to the direction of the plug to avoid damaging the interface by hard tugging).

Screw fixing: if the battery is fixed in the compartment by screws, unscrew the screws with a screwdriver and remove the old battery.

Pay attention to keep the fixing bracket or insulation of the old battery (if need to reuse).

3. Installing the new battery

Step Example:

Put the new battery into the battery compartment, make sure the position is correct and avoid squeezing the wires or parts.

Connect the power cord: align the battery plug with the body connector and insert it smoothly until it snaps into place (pay attention to the positive and negative terminals, some plugs have anti-reverse plug design).

Secure the battery with screws (if necessary) to ensure that the battery will not wobble while driving.

Cover the battery compartment cover and tighten the screws.

III. Precautions

Battery polarity and interface safety

Ensure that the positive and negative poles of the battery are consistent with the vehicle wiring to avoid reversing the connection and causing a short circuit or damaging the circuit.

Check whether the plug is firm to avoid loosening and falling off during driving.

Battery specification matching

It is strictly prohibited to use batteries with different voltage or capacity (e.g. 12V for the original vehicle, not 24V), which may damage the motor or cause potential safety hazards.

Lithium batteries need to pay attention to whether the protection board (BMS), to avoid overcharging and over-discharging.

Disposal of old batteries

Lead-acid batteries and lithium batteries are hazardous waste and should be recycled according to local regulations.

Contact the brand after-sales or professional recycling organisations to dispose of the old batteries.

Testing and Commissioning

After replacing the battery, carry out a power-on test first: switch on the vehicle, observe whether the dashboard indicator is normal, and confirm that there is no abnormality before test driving.

When using the new battery for the first time, it is recommended to fully charge it first (lithium batteries need to avoid overcharging) to activate the best performance.

IV. Handling of Special Situations

Integrated Battery Pack

Some high-end models or children's drift cars use integrated battery packs (such as welding or encapsulation design), which are difficult to disassemble by non-professionals.

Suggestion: Contact brand after-sales or professional maintenance personnel for replacement to avoid damaging the vehicle by self-operation.

Waterproof sealing design

If the battery compartment has a waterproof adhesive strip or sealing structure, you need to reinstall the seal after replacing the battery to ensure waterproof performance.

V. Maintenance Recommendations

Regularly check whether the screws of the battery compartment are loosened to avoid shifting the battery due to vibration during driving.

When not in use for a long time, it is recommended to take out the battery and store it to avoid battery loss and damage (lithium batteries need to be kept at 30%-50% of the capacity for storage).

If the drift car is used by children, it is recommended that parents regularly check whether the battery connection is safe to prevent children from accidentally touching it.

The above steps can safely complete the battery replacement of the electric drift car. If you are unsure about the operation, we recommend that you refer to the vehicle manual or contact the brand's customer service for guidance.
