The BlackVue's B-124X Ultra Battery is the successor and long-awaited upgrade of the B-124 Battery. Not only this is fast-charging, long-lasting and connected, it now features a USB port for powering accessories such as a mobile hotspot and also compatible with the 24V systems! Taking the advantage of the Cellink NEO's hardware, the B-124X Ultra Battery doubles the runtime of the previous-generation BlackVue B-112 battery pack while functioning the very same way: it recharges when your engine is running on and powers your dash cam when the ignition is off. If you are serious about protecting your car while it's parked and your dash cam supports Parking Mode by Motion Detection, this product will be the most comprehensive solution for powering your dash cam while parked.

Even though a typical car battery has a much higher capacity than Battery Packs, it is not designed for routine deep discharge cycles while the car is parked hence its performance may deteriorate and life is shortened prematurely over time. The BlackVue B-124X Battery works by charging a high-quality lithium iron phosphate (LiFePO4) battery while your car is running, and when it's turned off, the charged battery is then used to provide continuous power to your dash cam without the need to draw any power from your car battery. This process is very effective in reducing the risk of battery discharge, low voltage electrical warnings and flat car batteries. On top of that, you can connect the B-124E Expansion Battery to the B-124X Ultra Battery to more than double the capacity and parking recording time.

BlackVue B-124X Ultra Battery Wiring Scheme

The battery's Bluetooth connection allows you to check detailed information about the charge status and progress from your smartphone. The dedicated iPhone and Android apps are closely integrated into the BlackVue ecosystem and give out plenty of useful information about the battery, such as overall battery percentage, whether the unit is charging or discharging, how long it can power the camera for as well as how long it will take to fully charge and more.

Now enclosed in a metal casing, the B-124X has the look and feel of a premium product. Conveniently, its compact size makes it easier to pack and hide away into tighter spots. In addition to this, it places all the connectors and switches on the bottom of the unit making routing cables much easier and allowing for a much cleaner install.

Cables Explained

  1. Input 12V/24V Cigarette Plug Charger - Easier for install, however, charges the unit with a lower current of 5 Amps (takes 1 hour 20 minutes to fully charge)
  2. Input 12V/24V Hardwire Kit - Allows the battery pack to charge at a higher rate of 9 Amps so it is able to charge the battery in 40 minutes to full (please arrange a car electrician or our Auckland-wide Dash Cam Installation Service to hardwire it for you). Comes with a set of Add-A-Circuit fuse taps for a seamless installation.
  3. Output Dash Cam Cigarette Socket - This socket is compatible with any BlackVue and the Vico-Opia2 dash cams and, in essence, just a 12V/24V Power Outlet Female socket. If you have a BlackSys or a Thinkware dash cam, we can supply you with a compatible 3-pin spliced cable.
