Honda CR-V Dash Cam Installation Review: ACC Power Method

Why Your Honda CR-V Needs a Dash Cam Battery Pack

The Honda CR-V, a modern SUV packed with electronics, can quickly drain its main battery when a dash cam is set to parking recording mode. This is especially true in colder weather, where the constant operation of a dash cam can lead to battery discharge. The owner of this CR-V initially considered a direct connection to the main battery but opted for a separate battery pack to avoid potential damage to the vehicle's primary battery. The Cellink Neo 8+ Slim, installed by Today's Car Seocho, offers a unique solution.

Understanding Power Methods: Direct vs. ACC

The crucial aspect of dash cam battery installation lies in the power supply method. Many owners overlook this. A direct connection to the main battery might seem cheaper, but it risks leaving the car unable to start in emergencies due to over-discharge. In contrast, the ACC (Accessory Power) method utilizes the vehicle's regular power source, like the cigarette lighter socket. This system intelligently manages charging and discharging based on the ACC signal, even when the car is off. This approach prioritizes protecting the main battery while ensuring a stable power supply for the dash cam. The battery pack used in this installation employs this ACC method. A significant advantage is the "jack-by-jack" (plug-and-play) installation, meaning it's simple to revert to the original state if any issues arise, without affecting the car's original components.

Introducing the Cellink Neo 8+ Slim

This battery pack is a proprietary brand product from IZEN Co., Ltd., a domestic battery manufacturer. With a 7.5A capacity, it fully charges in about an hour of driving. For a dash cam consuming 320mA, it provides 24 hours of continuous parking recording, capable of lasting approximately 93 hours (nearly 4 days) on a full charge. A key feature is its use of Lithium Iron Phosphate (LFP) cells, offering superior safety and longevity compared to standard lithium-ion batteries. Furthermore, it comes with a 2-year free A/S warranty, adding to its reliability.

Installation Process:

1. Locate the vehicle's cigarette lighter socket, typically found under the steering column. Remove the cover and extract the ACC signal wire.
2. Connect the battery pack and dash cam using wiring that passes through a safety fuse and relay to prevent overcurrent damage.
3. Securely mount the battery pack under the passenger seat using anti-vibration materials to prevent movement during driving.

The Advantage of Bluetooth Connectivity

A standout feature of this battery pack is its dedicated smartphone app, allowing real-time monitoring of the battery's status via Bluetooth. You can check the charge level, estimated remaining parking recording time, and charging completion time. The app also allows setting a "charge stop function" to prevent overcharging when the vehicle is at a service center for extended periods. These thoughtful features contribute to a superior user experience.
