How To Install The BlackVue B-130X Power Magic Ultra Battery
Choose the charging input and camera output for dependable parking recording
Start with the right cables
The BlackVue B-130X has two separate connections: DC in charges the battery from your vehicle, and the Dashcam port supplies power to your camera. Start by identifying those ports and the matching cables. Mixing up the charging input and camera output makes the rest of the installation harder to follow.
We recommend the plug-in method if you want a simpler installation and have a suitable vehicle outlet. Hardwiring gives you BlackVue's faster listed charging rate, but it needs a correctly identified switched circuit and a properly installed fuse tap. If you're unsure about either, let a qualified installer handle that connection. Reliable parking recording starts with the right power setup.
This guide covers the Power Magic Ultra Battery B-130X. Keep the B-130X instructions with you while working, alongside your vehicle's owner's manual and your exact dash cam's wiring instructions. The B-124X and B-130A have their own installation details. For current options, browse our battery packs.
What to lay out before installation
Lay out the cables before you start. BlackVue's B-130X manual lists the battery, a cigarette-lighter input cable, a hardwiring input cable, two dash cam output options, a three-type fuse-tap kit, two Velcro strips and the user manual.
The output options are a female cigarette-lighter socket and a hardwiring output cable. Set them apart from the cable that will charge the battery. Use the genuine BlackVue cables specified for the B-130X, and check that the fuse tap matches your vehicle. The documented kit doesn't cover every possible fuse type.
Choose your charging method
Choose the charging method around your vehicle and driving routine. The figures below are BlackVue's listed charging estimates, not a promise that every drive will fully recharge the pack.
| Method | Connection to DC in | Listed charging current | Approximate charging time |
|---|---|---|---|
| Plug-in | Genuine cigarette-lighter input cable | 5A | 90 minutes |
| Hardwired | Genuine hardwiring input cable and switched fuse connection | 9A | 50 minutes |
Charging current is different from the fuse rating. Follow the fuse arrangement below for hardwiring, rather than choosing a fuse from the 9A charging figure. BlackVue's B-130X user manual contains the complete installation diagrams.
Plug-in installation
- Set the B-130X power switch to OFF.
- Connect the genuine cigarette-lighter input cable to the battery's DC in port and your vehicle's suitable accessory outlet.
- Connect the dash cam output as described below before switching the B-130X ON.
- Check that the battery starts charging while the vehicle supplies power to the outlet, then check what happens when you turn the vehicle off.
We recommend checking the outlet's behavior before you settle on a mounting position. Some vehicle outlets stay powered after shutdown. An outlet that remains live can keep drawing from the vehicle battery. Don't use a cigarette-lighter multi-socket splitter with the B-130X.
Use a switched circuit for hardwiring
The B-130X charging input uses switched accessory power, marked ACC, plus ground. ACC here means a supply that turns off with the vehicle's accessory or ignition circuit. Connecting this input to constant battery power can deplete your vehicle battery.
Use the vehicle's owner's manual to identify a suitable interior fuse circuit. BlackVue gives cigarette-lighter and car-stereo circuits as examples, not a fuse location that applies to every vehicle. Avoid choosing a circuit just because the slot is easy to reach.
Prepare the input cable and route
Leave the B-130X switched OFF while making the connections. Plug the genuine hardwiring input cable into DC in. Its ACC lead goes to the fuse tap, and its ground ring goes to a suitable bare-metal ground point on the vehicle frame.
Plan the cable route before removing trim. Keep wiring clear of pedals, moving seat mechanisms and airbag paths, following the vehicle's service guidance. If trim or safety-system routing is unfamiliar, this is a good point to bring in an installer.
Identify the circuit and fuse-tap type
BlackVue's B-130X manual specifies a switched accessory fuse of 10A or less. Identify the circuit using your vehicle documentation and suitable electrical testing. The vehicle circuit and the battery's new branch have different fuse roles.
Match the fuse-tap type to the removed fuse and confirm the supply side of the slot before installing it. Our add-a-fuse guide explains the tap arrangement. If you're choosing tools, check the actual contents of our Essential Install Kit against the work your vehicle needs.
Keep the two fuse roles separate
- Crimp the battery input cable's ACC lead securely into the fuse-tap connector.
- Put the removed vehicle fuse in the tap slot closest to the blades. For an original low-profile mini fuse, the B-130X manual specifies the included 10A mini fuse instead. Have your installer resolve any conflict with the vehicle's specified protection before proceeding.
- Put a new 20A fuse in the slot farthest from the blades for the battery branch.
- Install the tap in the identified switched slot, in the orientation shown in the B-130X manual. The new battery branch must receive power directly from the supply side, without passing its additional load through the original circuit's fuse.
- Secure the ground ring to a suitable ground point directly on bare vehicle-frame metal.
The 20A fuse protects the new battery branch. Don't replace the vehicle circuit's fuse with a 20A fuse. A reversed tap can put the additional load through the original fuse and cause it to blow. Have an installer confirm the circuit and orientation if you can't establish them confidently.
Secure the pack away from heat and moving parts
Secure the pack with the supplied Velcro strips so it can't move around. Under-seat and glove-box locations can be practical options, but the actual space must keep the battery and its cables clear of seat travel, hinges and other moving parts. Keep it away from direct sunlight, heat and liquids.
BlackVue lists a charging range of 0°C to 45°C and a discharging range of -10°C to 60°C. Its high-temperature charging cutoff is a protective limit, not permission to use a hot mounting location. We recommend choosing the location before finishing the cable route, so you aren't left pulling a connector tight to make it reach.
Connect the dash cam output
Connect the selected output cable to the port marked Dashcam. Use the female socket output with the camera's compatible plug-in power cable, or use the B-130X hardwiring output with the correctly matched camera hardwire cable.
The camera-side hardwiring output is separate from the ACC and ground connection that charges the battery. If your setup uses a three-wire camera connection, follow the documented BATT, ACC and ground functions for those exact cables. Wire color alone isn't enough to establish a match.
Parking-mode entry depends on the camera, cable and settings. An ignition-sensing connection and a camera that switches after being stationary can behave differently. For BlackVue X and X Plus models, confirm the exact model's instructions rather than assuming every camera switches immediately or uses a fixed five-minute delay.
Check charging and a saved parking recording
Once the wiring and camera output are connected, switch the B-130X ON. Check charging with the vehicle running, then turn the vehicle off and confirm the camera continues operating from the pack. Review a saved parking recording before relying on the setup overnight.
The B-130X's red charging light indicates charging and its green light indicates a full battery. Repeated warning beeps or unusual red/green patterns need attention. If the pack develops an unusual smell, unplug it immediately and contact support. If it swells, stop using it and contact support. Don't bypass a warning or open the pack to troubleshoot it.
Check the battery information over Bluetooth
Use Bluetooth to check the B-130X's battery information in the supported BlackVue app. The B-130X manual documents both the main BlackVue app's battery function and the separate BlackVue Battery app. Its screenshots show an earlier interface, so the controls on your phone may look different.
- Turn the B-130X ON and enable Bluetooth on your phone.
- Open the app's battery function and select your battery from the nearby devices. Use the pack's Bluetooth ID to identify it if needed.
- Use the app's rescan control if the battery doesn't appear, then follow the app's connection prompts.
The displayed time to full charge and remaining use are estimates based on the present input or power draw. Use them to judge whether your driving routine is replenishing the pack, rather than treating a displayed number as guaranteed parking coverage.
BlackVue's battery-management integration article explains the earlier app change. For your B-130X setup, use the battery's own manual and the app version that supports your phone.
B-130X installation questions
Can I connect the charging input to constant power?
No. The B-130X hardwired charging input requires a switched accessory circuit. Constant power can continue drawing from the vehicle battery after shutdown. Keep that input separate from any BATT connection on the camera-side output cable.
Can I charge the B-130X through USB or with a home adapter?
The USB port is an output. The manual specifies the DC in connection for charging. If you need to charge outside the vehicle, ask us about a manufacturer-supported power supply for this exact pack before buying an adapter. A connector that fits or a forum suggestion alone doesn't establish compatibility.
Why is my B-130X not charging?
Check that the pack is ON, the input cable is in DC in and the vehicle is supplying the required power. For a hardwired setup, have the switched circuit, fuses and tap orientation checked. Charging also has a temperature range. Stop if the pack reports a warning instead of repeatedly replacing fuses.
Will a full battery always last through the night?
Parking time depends on the camera's power draw and the battery's available charge. BlackVue's approximately 30-hour figure assumes one camera consuming 3W. Check your own saved parking files and recharge pattern before choosing the amount of coverage you need.
