FAQ

How do you view the battery voltage?

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!

Can you see individual cell voltage?

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

What do the values mean on CHEK when a battery is first plugged in?

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

  • 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.

How accurate is CHEK?

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.

It is recommended to begin flight with a battery that is fully charged.

Will CHEK work on any other types of batteries?

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