Designed by BlackboxMyCar

The BI-750 is a dash cam battery designed, tested and backed by your most trusted dash cam name, BlackboxMyCar. The battery is engineered and assembled in South Korea.

Upgraded hardware with new technology, the BI-750 is designed to deliver the ultimate combination of power, durability and flexibility, helping you get the most out of your dash cam's parking mode capabilities.

Higher Capacity for More Power

The BlackboxMyCar BI-750 recharges with ignition on and powers your dash cam when ignition is off.

Higher Capacity: with a capacity of 96Wh/7500mAh, the BI-750 gives you 25% more power than the Cellink NEO or the BlackVue Power Magic Ultra Battery B-124X.

Faster Charging: despite a higher capacity, the BI-750 reaches a full charge at as little as 40 minutes in dual-charging mode (80 minutes if connected to the cigarette lighter socket).

Multiple Connections Options

Input Cables

The BlackboxMyCar BI-750 comes with multiple input cables and options, including a 12V Power Cable that you can plug into the cigarette lighter socket in your vehicle (Charging current: 5A. Charging time: approx. 80 minutes) and a Hardwiring Cable that you can connect to your vehicle's fuse panel for a faster charging speed (Charging current: 6A; Dual-Charging: 12A. Charging time: approx. 40 minutes)

Output Cables

  1. Unspliced 3 Wire Output Cable - splicing to a dash cam hardwire kit will be required
  2. Thinkware Spliced Output Cable - plug and play cable for Thinkware dash cams
  3. Viofo Spliced Output Cable - plug and play cable for Viofo dashcams

Check Battery Status with App

Built-in Bluetooth allows the BI-750 battery to communicate with the Battery Manager app so you can easily check information like remaining capacity or time to full charge.

You can also use the Battery Manager app to control settings like charging current, voltage cutoff, LED indicators and more.


The LED indicators on the face of the BI-750 let you know if there should be any problems or issues with your battery.

Universal Compatibility with 2 USB Ports

Comes with a cigarette socket output for universal compatibility with most dash cams, including BlackVue, Thinkware, VIOFO and IROAD.

With two 2A USB Type-A ports, you can charge your phone, power your Wi-Fi hotspot for your Cloud dashcam or any accessory. Need to charge additional accessories? The BE-750 Extended Battery also comes with 2 USB Type-A ports so you can charge additional accessories.

Expansion Battery for More Power

The BlackboxMyCar BE-750 Extended Battery doubles your capacity. The BE-750 carries the same 7500mAh battery capacity, giving you more power than expansion batteries from other brands. You can even add more than one expansion in sequence.

Power Duration Capabilities

A fully charged BlackboxMyCar BI-750 battery pack can run a single 1-channel dash camera for up to 48 hours, while a dual-channel system can be run for about 35 hours with its integrated 96Wh. This measurement based on continuous runtime.

Changing Passwords

If you are planning on changing the battery password, you will need to enter the default password '0000' when prompted for the old password.

Note: There is no password retrieval or reset function. Password reset is a function that can only be performed by technicians at the manufacturer. The Reset function within the Battery Manager App is for resetting the default battery settings (ie. the Dual Charger setting) only and will not reset the password back to the default "0000".

Because of this, we strongly recommend that you don't change the password unless you absolutely needed to, and if you do change it, make sure to keep a record of the new password. Once you have changed the password, you will be asked to re-enter it every time you access the Settings menu within the Battery Manager App.

This latest entry into the battery pack market is an excellent investment for anyone who wants to protect their parked vehicle without ever having to hardwire their dash cam. I love the slim profile, USB ports, and, of course, large capacity. I use the BI-750 to power my Viofo A129 Duo while parked. I also have a Cellink Neo pack (made by the same Korean manufacturer) to power my Thinkware u1000 in parking mode and, although the older battery pack does a great job, the BI-750 raises the bar considerably.

I should mention, too, that the BBMC folks give amazing support. I had ordered the cigarette socket output (because I hadn't researched enough or asked pre-sales questions) and soon learned that it didn't support parking mode on the Viofo. The customer service person I finally called, was most helpful and informative. She immediately had the correct cable sent out and now the Viofo parking mode performs flawlessly. BTW, she also cheerfully generated a refund for the price difference on the BI-750 that had gone on sale. As promised on their website, BBMC truly did honour their price reduction guarantee. I wish I had known about these guys earlier - they would have saved me a lot of time (and probably $$, too)!
