## FAQ

<details>

<summary>How do you view the battery voltage?</summary>

To view the battery voltage, simply plug your 12s LiPo Battery into the AS150U or XT90 port. The voltage and percentage with appear on the screen. No setup is required!

</details>

<details>

<summary>Can you see individual cell voltage?</summary>

No, you can only see the overall battery voltage. If you would like to see individual cell voltage, we suggest viewing with a charger.

<summary>What do the values mean on CHEK when a battery is first plugged in?</summary>

When a battery is first plugged into CHEK, the values 43.2 and 49.5 will display on the screen.&#x20;

* 43.2V represents 0% battery remaining
* 49.5V represents 100% battery remaining

Any voltage that is below 43.2V will read 0%, and any voltage above 49.5V will read 100%. These values are hard coded and cannot be changed.

</details>

<details>

<summary>How accurate is CHEK?</summary>

CHEK measures the real-time voltage of the battery and uses it to estimate its state of charge. This will then correlate to a percentage remaining, as displayed on the screen. Real-time voltages can fluctuate based on temperatures and other environmental conditions. This product is only intended to be a quick check to tell if the battery has already been used.&#x20;

It is recommended to begin flight with a battery that is fully charged.&#x20;

</details>

<details>

<summary>Will CHEK work on any other types of batteries?</summary>

CHEK will only display accurate voltages for 12s LiPo batteries.
