Never over-discharge your LiPo cells! This can happen simply by flying too long, which can seriously reduce the life of your cells and even damage them!
A sensor dedicated to accurately indicate the critical voltages of your Lithium Polymer Cells while you fly. Can be run in either ‘Normal’ mode or “diagnostic’ mode.
A high intensity LED blinks in a particular sequence to indicate a specific voltage so you know when to land without risking your expensive LI-Po Packs!
The Undervolt sensor can also have a Piezo Buzzer for audible alarm. Simply plug it into the Sensor.
Microprocessor controlled and has many advanced features please take a look at the instruction Manual.
All Sensor Units are conformal coated in PCB lacquer and is liquid resistant so there is no need for heat shrink-wrapping.
The Undervolt Sensor is no longer offered for sale as a fully assembled product.
Software files will be released as downloadable ‘freeware’ along with Circuit schematics for DIY projects. (Soon)
Parts, printed circuit board and programmed Microcontroller will be offered for sale in kit form for DIY project soon.
