How to Install Cellink Battery B (2.0)

Cellink Battery B

Hello, Alex from here. Today we are going to show you how to install a Cellink Battery B into your vehicle. Before we get into that though, I’d like to stress just how important it is to hardwire a dash cam if it has a dedicated parking mode feature. I’ve said this before in our Power Magic Pro installation guide, but some dash cam owners are fine with only recording video when the car is turned on, while other dash cam owners want a dash cam that continues to record even when the car is turned off. Those who want a dash cam that only runs when the car is on can use what we call the “Plug & Go” method, while those who want a more vigilant eyewitness can opt for a hardwiring kit like the Power Magic Pro, and for those who want the absolute best parking mode recording, they would get the Cellink Battery B.

What is a Cellink Battery B?

The Cellink Battery B is the best battery pack we offer for managing parking mode functions. The Cellink Battery is an excellent alternative to traditional hardwiring kits as they provide a much longer source of power for your dash cam, and puts less strain on your car’s battery. Cellink Batteries look quite large in their product pictures but they are about the length and width of an iPad and about ⅓ the height of a tissue box. This means that the Cellink is the perfect size to go underneath a car-seat or into the glovebox.

A Cellink Battery B can be hardwired into an ignition switched fuse in your car or plugged into one of your car’s cigarette sockets to charge itself. A Cellink battery takes around 1 hour to 1.5 hours to fully charge but can provide around 20-30 hours of parking mode recording once it is charged. Once your car is switched off the Cellink will jump in and provide the charge that it has been building up to your dash cam, letting your car’s battery rest and prolonging its life; this way, you will get power for parking mode recording without ever draining your vehicle’s battery. You can learn more about the Cellink Battery B through our review.

Now the instructions I’m about to give for integrating a Cellink battery is going to be as general as it can be, because different cars have different fuse box setups.


The first thing that we need to do is decide on which setting the Cellink battery will be the one that we want to use. The Cellink has a switch on its side with 3 options: 7amp, 5amp, and off. 7 amp is used when the Cellink Battery is charging through a hardwire connection to the fusebox, while 5 amp is used when charging through other means sources such as a power inverter or a cigarette socket in your car. Off is an option for customers if they do not want to use parking mode.

The second thing that you will need to do is find out where your fuse box is located. This is different for every model of car, but there should be some information on this within the owner’s manual. Once you have found the fuse box, you need to locate an ignition switched fuse that is at least 10A (keep in mind that a hardwired Cellink B will draw 7A so 15A would be better, but 10A will work). Once you’ve identified which fuse to use we can begin hardwiring your Cellink Battery B into your car. Preferably we go for fuse boxes that are located in the cabin as these are the easiest ones to work with.

When hardwiring the unit to charge, you will only have one wire that you need to link up to your fuse box. The other wire has a loop on the end and is a grounding wire, which will be linked to a grounding bolt near the fusebox. You’ll know which set of wires I’m referring to by the yellow tab that connects it to the input wire on the Cellink. That yellow tab is used to connect to the wire that is labelled “input” on the Cellink’s body.

Circuit Tester

The fuses that can be used vary from car to car, so you will need to test your fuses using a circuit tester like this one. These circuit testers need to be grounded first and work by lighting up if you poke them in the holes on the fuses with metal poking out. Fuses that cause the tester to light up when the car is on and the car is off are considered “Constant Fuses” while fuses that light up only when the car is turned on are “ACC” or “Accessory Fuses”.

The first wire that we will look at is the grounding wire. The grounding wire is the black wire with the circular metal ring protruding from it, and exists to mediate the voltage going to the units. The grounding wire needs to be hooked up to a grounding bolt, like this one. You can do that by unscrewing the bolt, and placing the ring from the wire onto the screw, in between the bolt and the frame. With the ring set, tighten the screw, so that the ground will not wiggle loose when driving.

The second wire is the black and white ACC wire. As mentioned earlier, this wire needs to be placed in a fuse that is off when the car is off. We suggest using an Add-a-Fuse kit to plug the wire into your fuse box as the Cellink has fairly thick wires that we don’t recommend wrapping around a fuse leg and plugging back in.


Special Hardwiring Situations

BlackSys External Power Setting

There are some dash cams out there that have a dedicated parking mode which requires a direct hardwiring kit. These dash cams can still use the Cellink Battery, though there are some steps that will need to be taken to do so. With the BlackSys CH-100B, you would need to make sure that you activate the External power source setting, in the settings. When you do you will get a list of options for when to go into parking mode. We find 10 minutes to be the best option to use, as it’s just in the sweet spot of not being too fast and not being too slow on activating parking mode.

Hardwiring with a Cellink Battery B

Some of our dashcams, such as the Thinkware F750 and eCELL Focus have direct hardwiring kits similar to that of the BlackSys CH-100B but do not have the external power option in the settings like the CH-100B. Because of that, these units would need to be spliced into the Cellink Battery in order to be advantage of the extra power source. To do this, you would need to match the cables of the respective dashcam’s hardwiring kit with the Cellink’s female cigarette socket. This is why the new Cellink models come with the loose wires and the red wire loop, so that dashcams with direct hardwiring kits can connect together without issue.

Non-Hardwiring Options

The Cellink Battery B also has another way to charge itself. We offer a 12 volt male cigarette jack that allows the Cellink to charge using one of your car’s cigarette sockets. This also gives you the option to charge the Cellink at home through a device like the power inverter we mentioned earlier. It is important to make sure that your power inverter can output at least 5 amps, because anything less than 5 amps will not be able to charge the Cellink properly.

If your Cellink is plugged into your car’s cigarette socket, and that socket has a constant charge, then you will need to find another cigarette socket to use. This is because your Cellink will continue to draw power from your car’s battery even when your car is parked, as it doesn’t have a way to tell that your car is parked. If you are looking for a way to get the parking mode features from your dash cam, but not wanting to hardwire your setup, then it is important to make sure that your cigarette sockets aren’t constantly powered.

After finding a good place to mount your Cellink Battery B, you can now power your dash cam with your Cellink. You do this by plugging your dashcam’s male power jack into the female cigarette socket of your Cellink. With your dashcam’s set up using one of the two methods that we have detailed for you, your dash cam will be ready to be the silent witness that you’ve wanted.
