VIOFO BP100 Battery Pack with Accessories

Q: How does the BP100 compare to just using a hardwire Kit?

A: A hardwire kit (HK4 or HK6) draws power from your vehicle’s 12V battery and uses voltage cutoff to prevent a dead car battery. The BP100 is a separate, dedicated battery that does not touch your car battery at all — it charges while driving and powers the dash cam independently when parked. The BP100 provides more predictable and longer parking coverage, especially in cold climates where car batteries lose capacity.

Q: How long does the BP100 last with different das cam models?

A: Recording time depends on your dash cam’s power consumption and recording mode. Approximate runtimes with BP100 alone (7650mAh): A329S 1CH low-bitrate parking mode — up to 27 hours; A329S 2CH — up to 18 hours; A329S 3CH — up to 14 hours; A229 Pro 2CH — up to 20 hours. Higher-resolution modes and more channels consume more power. Adding an EP100 expansion battery extends these times proportionally.

Q: Can I leave the BP100 in my car during summer heat?

A: The BP100 includes a temperature protection system that monitors internal battery temperature and automatically stops charging or discharging if temperatures exceed safe limits. However, like all lithium batteries, extended exposure to extreme heat above 60°C (140°F) should be avoided. Park in the shade when possible, and the BP100’s thermal management will handle normal hot-weather conditions.

Q: How many EP100 expansion batteries can I connect?

A: You can connect up to two EP100 expansion batteries to a single BP100, roughly tripling the total capacity and parking recording time. The EP100 units daisy-chain to the BP100 via a simple cable connection. After connecting, you must set the number of expansion batteries in your dash cam’s settings so the system can accurately calculate remaining power and runtime.

Q: What’s the difference between BP100 and EP100?

A: The BP100 is a battery pack, providing a rechargeable power source for your dashcam.
The EP100 is an Expansion Battery for the BP100 Battery Pack and can’t work separately. It needs to be connected to the BP100 to get it to work.

Q: Is BP100 compatible with my dashcam?

A: Yes, the BP100 battery pack is compatible with all VIOFO dashcams. Please make sure you’re using our original cables.

Q: Do I need to order EP100?

A: The capacity of the BP100 battery pack is 7650mAh. If it is not sufficient for you, then we recommend EP100.

Q: How to install the BP100, or how wuold the HK4 / HK6 worth with the battery pack if you already have it installed?

A: BP100 comes with its own power supply cables(not including the hardwire kit). You need to remove the HK4/HK6 hardwire kit from the car battery first.

Input for BP100 Battery Pack (2 Options):
1. Connect the Hardwiring Power Input Cable (3M) from the BP100 to your car’s battery (or the fuse box, depending on the setup).(Recommended)
2. Plug the Cigarette Lighter Plug Power Input Cable (2M) into your vehicle’s cigarette lighter socket and connect the other end of the cable to the BP100 battery pack.

Output for the BP100 Battery Pack (3 Options):
1. Using the Hardwire Output Cable (Type-C, 4M) to connect the BP100 to the dashcam GPS power port directly. (Parking mode supported). (Recommended)
2. Using the Hardwire Output Cable Adapter (2M) to connect the BP100 to the HK4/HK6 hardwire kit to power the camera. (Parking mode supported).
3. Using the Cigarette Lighter Output Cable (0.3M) to connect the BP100 to the original car charger to power the camera. (Parking mode not supported).

Q: Do I still need to buy / install the hardwire kit if I have the BP100 Battery pack?

A: No, a hardwire kit is unnecessary. BP100 comes with a Hardwire Output Cable (Type-C, 4M) that supports parking mode.

Q: What should I do if I cannot find BP100_XXXX in my Bluetooth list?

A: If the battery device does not appear on your phone, please follow these troubleshooting steps:
1. Power On the Device: Ensure the battery is powered on first. The Bluetooth module activates automatically only after the device is turned on.
2. Check Proximity: Keep your phone and the battery within a range of 10 meters (33 feet) to ensure a stable signal.
3. Check App Permissions: Go to your phone’s Settings, locate the battery companion app, and ensure that Bluetooth Permissions are toggled ON.
4. Reset Bluetooth Connection: If your phone’s Bluetooth is already on but the device isn’t showing up, try toggling it OFF and then back ON to refresh the search list.

Q: How to handle Low Voltage and High Temperature pop-up alerts?

A: Low Voltage Alert: When the battery drops to 10%, a low voltage pop-up will appear. You can simply ignore it or manually close it by clicking the icon X in the top-right corner. The battery will not shut down automatically at this point; it will only power off when the level reaches 0%.

High Temperature Alert: A high temperature pop-up will appear if the battery reaches 70℃+-5℃ during discharge, or 50℃+-5℃ during charging. You can ignore the alert or click the icon X in the top-right corner to close it. The battery will not shut down immediately, but it will automatically power off if the temperature exceeds the 70°C safety limit.

Q: Why is Parking Mode not working?

A: To enable Parking Mode, please ensure the following requirements are met:
Use the Correct Cables: You must use the specific cables provided in the battery box: either the Hardwire Output Type-C Cable (4M) or the Hardwire Output Cable Adapter (2M).

Correct Wiring (for Hardwire Output Cable Adapter): If you are using the adapter cable, ensure the colors match correctly:
Connect the Red wire to the Hardwire Kits Red wire.
Connect the Yellow wire to the Hardwire Kits Yellow wire.

Important Connection Note: To support Parking Mode, the cable must be plugged into the Output (Parking Mode Supported) port. The Type-C port on the battery is strictly for mobile phone charging only.

Q: Why must I manually set the number of expansin batteries, and what happens if I set it incorrectly?

A: Automatic vs. Manual Detection: When only one expansion battery is connected, the device can automatically detect it and update the count to 1.
However, when two expansion batteries are connected, the device can not automatically update the number of expansion batteries. Therefore, you need to manually change the number to 2 within the app settings.

Impact of Incorrect Settings: If the battery count is set incorrectly, the following four parameters displayed in the App will be inaccurate:
a. Remaining Charging Time
b. Remaining Usage Time
c. Battery Capacity
d. Battery Percentage (%)

Q: How Long will the BP100 battery pack supply power for A329S 3CH with Parking Low bit rate recording?

A: For A329S 3 CH, it can record about 12 hours when the battery is fully charged during parking mode. If you usually park your car for a long time, you can consider adding the EP100 Expansion Battery. And the battery packs can be charged again during your next drive.
