  • Summary

    This is the expansion pack for the Cellink Battery B that doubles the parking mode recording time for your dashcam. It must be charged through the main battery and as a result a longer charging time should be expected than just the main battery itself. It's the perfect choice for someone with longer commutes and needs considerably more parking mode recording time than a traditional hardwire kit or the Cellink Battery B offers on their own. The Cellink dashcam battery packs are a great way to avoid low battery discharge warning messages on newer vehicles with sensitive electronics, read our post here on the topic.

    Battery Discharge Protection

    The second generation Cellink Battery B connects only to an ACC fuse meaning that it poses no risk to the vehicle's main battery. Avoid low battery warning messages on newer vehicles by using the Cellink Battery.
