2026 Kia EV9 battery pack for your dash camera installation
Installing a VIOFO battery pack in the rear of a 2026 Kia EV9 lets you power a dash camera independently without impacting the vehicle battery. The EV9’s rear storage area and available spare fuse make this a straightforward, non-invasive install when done carefully.
What you need to know before you start
This installation uses a three-wire battery pack that requires:
- Constant positive (for charging)
- Ignition/Accessory trigger (so the pack knows when to charge)
- Ground (vehicle chassis ground)
Key advantages of the approach below: it uses a spare fuse location so you don’t disrupt existing circuits, taps the cigarette lighter’s accessory wire for ignition, and uses a factory ground bolt for a reliable return.
Step 1 — Access the rear panel and locate the fuse box
Remove the rear paneling to access the EV9’s fuse box hidden behind the trim. Look for an unused/spare fuse slot — this is ideal for a fuse tap because it avoids impacting in-use circuits.
Step 2 — Use a spare fuse tap for power
Install a fuse tap into the spare fuse slot to obtain the constant and/or switched power you need without cutting factory wiring. A properly chosen spare fuse means the vehicle’s original circuits remain untouched.
Step 3 — Get the ignition signal from the cigarette lighter
Because the VOFO battery pack requires an ignition signal, tap the cigarette lighter’s accessory wire on the back side for the ignition input. This provides a clean accessory/ignition source that behaves correctly when the vehicle is turned on or off.
Step 4 — Connect a reliable ground
Use a factory ground bolt in the rear to complete the circuit. Using an OEM ground point avoids loose connections and corrosion issues common with improvised grounds.
Step 5 — Route the wires and mount the battery pack
Remove any small access plates in the rear cargo area and modify them if necessary so the wiring can pass through neatly. Secure the battery pack with 3M double-sided tape or equivalent mounting hardware to keep it fixed in the storage area.
Step 6 — Verify operation and conceal the install
With the pack mounted and wiring routed through the panel, turn the vehicle ignition on to verify the VOFO pack is charging and the dash cam receives power as expected. Once confirmed, close up the panel so the battery pack and wiring remain hidden in the rear storage area.
Installer tips and best practices
- Identify the right fuse: Confirm the spare fuse slot is truly unused and not tied to a critical vehicle function.
- Use proper fuse taps: Quality fuse taps ensure a reliable connection and reduce the chance of blown fuses or intermittent faults.
- Label connections: Mark the ignition, constant power, and ground leads so future troubleshooting is faster.
- Secure wiring: Route cables away from moving parts and use zip ties or loom to prevent abrasion.
- Test before final assembly: Always power-up and monitor charging behavior before snapping panels back into place.
- Consult vehicle documentation: If unsure about fuse assignments or locations, check the EV9 owner manual.
Why this method works well for the EV9
The EV9’s layout allows a compact, hidden installation in the rear storage area. Tapping the cigarette lighter accessory makes the ignition trigger simple and non-destructive. Using a spare fuse and factory ground keeps the install reversible and preserves factory wiring integrity.
Quick checklist
- Spare fuse identified and ready for fuse tap
- Ignition accessory wire tapped behind cigarette lighter
- Factory ground bolt used
- Battery pack secured with 3M tape or brackets
- All panels reinstalled and cables hidden
Done correctly, this approach delivers a clean, hidden dash camera power solution for the 2026 Kia EV9 while keeping factory systems intact and easy to restore.
