LBA2S 2S Low Battery Alarm
[LBA2S 2S]

 Preset 2 cell Lipo alarm - 80dB piezo  (4 grams)

For 2 cell Lama style / small models

Wire in parallel to the speed controller by:

1) Wire on the back of the ESC – battery connector.

2) Wire across the leads going from the connector to the ESC.

Stick the alarm to the underside of your model. The

Alarm beeps when your battery goes below 6.6v. The 6.6v is chosen, as that represents 3.3v per cell for a 2S battery. If a Lipoly battery goes below 3.0v it prematurely ages the pack, where it may not perform or last as well as it did. Below 2.7 per cell, the lipoly cell will be damaged permanently. I recommend the 3.3v per cell (6.6v for 2S) as it is at the point where (on the graph) the voltage drops away quickly. This limit will give you time to land, protecting the battery.
