This Lithium Polymer Battery Tester with Low Voltage Alarm features loud twin piezoelectric buzzers and a LED to notify you once your cells reach a user-defined voltage. This unit also features a handy built-in LED display that will show the voltage of each cell followed by the overall voltage of the pack.

Don’t risk your model by flying on depleted batteries!

Key Features:

• Officially supported in the ELEV-8 V2 Assembly Guide.
• Connects directly to the batteries balancing lead – no extra connectors or wires necessary.
• Twin piezoelectric buzzers may be heard from over a hundred feet away.
• Easy to program – just press the micro switch (under the buzzers) until your desired alarm voltage level is displayed. We recommend 3.5 volts for LiPo batteries.

Application Ideas:

• Mount it directly to your Parallax ELEV-8 v2 Quadcopter Kit – never wonder when it’s time to land.
• Use it to check battery pack and individual cell levels before or after use.
