Quickly test your LiPo before flight, and it can be used as an inflight alarm if you are unsure of the maximum flight time.

With a push key, you can change the value settings and save them.

When the voltage is below the set value, it will buzz very loudly with a red LED light. (Pre-set value is 3.3V)

Mini shape; it is no larger than a common key.

Compact and easy to carry.

Really useful in flight if you cannot see the lights.
