VIOFO EP100 — Expand Your BP100 for Much Longer Parking Surveillance

The EP100 is an expansion battery module that connects to the VIOFO BP100 battery pack to significantly extend parking mode recording time. Each EP100 adds substantial capacity — connect up to two EP100 units to a single BP100 to roughly triple your total parking surveillance time. If 32 hours of parking protection isn't enough, the EP100 makes multi-day coverage possible without touching your vehicle's battery.

Simple Expansion, No Replacement Needed

The EP100 connects to the BP100 via a simple cable — no tools, no complex installation. After connecting, set the number of expansion batteries in your dash cam's settings, and the system automatically manages power distribution and displays accurate remaining runtime via the VIOFO Bluetooth app. The EP100 charges through the BP100 while you drive, so the entire system stays topped up automatically.

Ideal for Multi-Day and Fleet Parking Protection

One BP100 + one EP100 covers most weekend parking scenarios. One BP100 + two EP100 units provides extended coverage for airport parking, vacation trips, fleet vehicles parked overnight, or any situation where your vehicle sits unattended for days. The BP100's temperature protection and battery management extend to all connected EP100 units for safe, reliable long-term operation. 

*Important: the EP100 cannot function on its own — it requires a BP100 as the base unit.

Frequently Asked Questions

Can I use the EP100 without a BP100?
No. The EP100 is an expansion module that must be connected to a BP100 battery pack to function. It does not have its own power management, charging circuit, or output ports. The BP100 serves as the controller and charger for all connected EP100 units.
How much extra recording time does one EP100 add?
Each EP100 adds capacity roughly equivalent to the BP100 itself. With one EP100, expect approximately double the recording time compared to BP100 alone. With two EP100 units, expect approximately triple. Exact runtimes depend on your dash cam model, number of channels, and recording mode.
Does adding an EP100 affect charging time?
Yes. Charging BP100 + EP100 together takes longer than charging the BP100 alone, since the total capacity is larger. However, the system charges through the BP100 while driving, so for most daily commuters the entire system stays topped up during normal driving. Longer initial charge times are only noticeable when charging from empty.
How do I connect the EP100 to the BP100?
Connect the EP100 to the BP100 using the included cable — it is a simple plug-in connection with no tools required. After connecting, go into your dash cam's battery settings and set the number of expansion batteries so the system can accurately display remaining power and runtime. The VIOFO Bluetooth app will show the combined battery status.
Is the EP100 worth buying, or should I just get a second BP100?
The EP100 is specifically designed to expand a single BP100 system. A second BP100 would require separate installation, separate cables, and cannot share power management with the first unit. The EP100 integrates seamlessly — one system, one Bluetooth connection, one status display, automatic power distribution. It is the intended and most efficient way to extend your parking recording time.
