Expansion battery pack for NEO 6 and NEO 8+ batteries
Please note: the EXT 7+ is an expansion pack and cannot be used on its own.
Each EXT 7+ has a capacity of 87.04Wh, providing additional constant recording time when powering a dash cam. In real-world use — where the dash cam records only when motion or impact is detected — operation time is typically measured in days rather than hours.
Multiple EXT 7+ packs can be connected in sequence to multiply recording time, up to a maximum of 5 packs.
Cellink NEO battery packs charge a LiFePO4 battery via the cigarette lighter socket or directly from the vehicle's electrical system while the engine runs. When the ignition is off, the charged battery powers the dash cam without drawing from the vehicle battery, reducing the risk of battery discharge or low-voltage warnings.

About the Cellink EXT 7+
From our tech experts at CEN
A dedicated dash cam battery pack, powering parking mode from its own cells so the vehicle battery is never touched.
Who it suits
Drivers who park on the street or leave the car for days at a time, and EV owners, where drawing from the 12V system in parking mode is best avoided. It is also the answer on cars whose voltage cutoff keeps shutting the camera down early.
Our tech experts advise
It charges while you drive, so a normal commute keeps it topped up. Mount it somewhere secure and ventilated, usually under a seat or in the boot. We fit battery packs alongside camera installs at our Beeston workshop. See dash cam installation.
