B100 Battery Pack
Table of Contents
【Battery Description】
The key indicator that shows the battery level is on the right side of the battery.
The USB-C of B100 only supports input and does not support output. So it cannot be used as a mobile power source.
The B100 is powered by 2 x 5000mAh/3.65V cells, 10000mAh is the total capacity of the cells
B100 can be automatically calibrated.
【How To Charge】
B100 USB port adopts dynamic charging power, the maximum power is 15W, please use 5V3A charger to charge.
We suggest using Quest's original charger and charging cable, or the charging cable we provide, to charge B100 separately.
The indicator lights of the battery are normal, but if the charging time becomes longer or cannot be fully charged, there is a significant relationship between the charging cable and the charger. Need to use high-quality chargers and charging cables.
Charging time of different chargers:
USB C 5V2A: Charging time is about 4 hours, usually about 4 hours and 10 minutes;
USB C 5V3A: Charging time is about 3.5 hours, usually about 3 hours and 25 minutes.
The battery utilizes fast charging to quickly reach 80% of its capacity, then switches to a slower trickle charge. The time required to reach the initial 80% may vary depending on your charging device. If the battery temperature exceeds the set threshold, charging will pause temporarily and resume once the temperature decreases.
【Charging With Quest 3?】
When the B100 is plugged into the USB charging cable and magnetized to the S3, there will be 2 scenarios:
- When B100 is above 5% and below 30%, only B100 may be fully charged. The Quest 3 charges for a while and then stops charging and only charges the B100.
- When B100 is above 30%, both B100 and quest 3 will be filled. However, B100 will be consumed by quest 3.
The above is for 5V 3A charger, the actual situation is slightly different from the above. Also, please make sure your charger will not activate the auto power off function, otherwise the B100 will not reach 100%.
Official recommendation: Charge the B100 and quest3 separately. Use a good quality charger as well as charging cable to charge B100 separately.
【Repeated Connect The Charging Cable】
Needs to be plugged in several times to charge possible reasons:
- The connected USB cable is of poor quality or too long, resulting in B100 input undervoltage not charging. Or the 5V output of the charger can not be continuously stabilized resulting in B100 input undervoltage protection.
- When the power level is below 0%, when the power level is particularly low, plugging in the USB may take a few seconds before the indicator lights up.
- When the B100 power is lower than 1%, it is in trickle charging state, the charging current is relatively small. If the charger or charging cable has an automatic power-off function, it may stop charging.
Official Recommendation: Replace a good quality charger as well as charging cable to charge the B100 separately.
【Plug In Charger Indicator Does Not Light
Up When Power Is Low】
After the B100 power is below 0%, if it has not been charged for a long time, in order to protect the battery cell will enter a deep sleep state, at this time, pressing the button will not show the power level, and plugging in the charger will also need to wait a few seconds to wake up the battery.If there is a serious power loss, the waiting time will be longer.
【Power Indicator Not Light Up After
Magnetization】
The power indicator does not light up when the B100 is magnetized?
The indicator light does not come on when the B100 is discharged, it only comes on continuously when charging.
【B100 Charging Exclusion Index】
Regarding the charging issue with the B100, please consider the following:
- If the battery is extremely low, it is recommended not to charge it while attached to the headstrap. Instead, remove it from the headstrap and charge it separately.
- Use the original charger and cable for the Quest to ensure proper charging. Using a splitter or an excessively long USB cable may hinder charging.
- If the B100 has a very low battery and no LED indicators light up when pressing the buttons, it may take about 3-5 seconds for the charging indicator to activate. If the battery has been fully drained or left unused for a long time, it may take around 5 minutes for the charging indicator to appear. Please charge the B100 separately using the original Quest charger and cable, or the provided charging cable. Wait for 5 seconds to 5 minutes and observe the charging indicator on the B100.
- Charging the Quest while it is placed in a sealed bag or in a high-temperature environment can cause the battery temperature to rise, triggering temperature protection. After approximately 10 minutes, once the temperature decreases, charging will automatically resume.
- Try flipping the USB charging cable to check if both sides of the cable affect the charging functionality of the B100.
If the issue persists despite following the above guidelines, please provide a video demonstrating the problem and send it to our after-sales support team. This will enable them to better assist you in resolving the issue.
