Lipo Battery Voltage Meter With Programmable Buzzer Alarm 1.Low voltage buzzer alarm for 2-8S 2.Measure 1-6 Cell Lipo Battery

Lipo Battery Voltage Meter With Programmable Buzzer Alarm : Measures 1-6 Cell Lipo Batteries, 2.8V-25.2V, For All Helicopters  

New improved version with 0.01V accuracy (higher accuracy than its previous version) and 25.9V capacity per cell verses 22V or 6.2V capacity per cell on the previous version. Now you can measure voltage from either the charging or discharging leads of the battery. Normally a battery meter only measures 2-6 cell, this one does 1-6 cell. It is a hard to find total battery monitoring device that checks your pre-flight voltage and prolongs your lipo battery lifespan because you can frequently check its voltage effortlessly. This meter measures from 1-cell to 6-cell Walkera/Novus/Trex/Eflite/Esky helicopters batteries and features single hand test operation cumbersome voltage meters with lead wires and adapters. While batteries can easily be shorted while using a standard voltage meter, the fixed leads of this meter prevents the battery's negative and positive contacts from shorting. It will also be a good idea to purchase several of these inexpensive meters, one in each helicopter case and one on your work bench, so it is always available to protect your valuable lipo investment. How to use the meter.This meter is designed to measure 1 to 6 cell lipo and other types of battery cell that is below 22v per cell per channel. The meter has 6 channels -one channel per cell and each channel can read up to 25.9V with auto circuit protection if it goes over. The meter can be connected to the balancing plug or the discharging plug of the battery to obtain a voltage reading. To measure the voltage the correct way, you should plug the meter into the balancing lead of the battery if you have a 5 or 6 cell batteries so each cell can be measured separately to derive a total voltage up to 37.2v (6.2v x 6 cell). The meter will first give you a total voltage reading from all 6 channels combined then it will display each cell voltage individually. Example: on a fully charged 6 cell battery, it would display 25.2v total then followed by No 1 is 4.2v, No 2 is 4.2v, No 3 is 4.2v and so on.You can also install this small but advanced meter on board mini to larger sized helicopters so you have constant battery monitoring through out the flight. If the voltage drops below 3.3V, a small led will light up and the double alarms will buzz to give the pilot a warning. The alarm is especially useful when the helicopter is too far away for the pilot to see the led. Please note that helicopters have different operating voltage requirements so you will still need to set your own timing requirements with or without the help of the alarm.   FeaturesUse for 1-6S Lipo/Li-ion/LiMn/Li-FeVoltage Detection Precision: + or - 0.01VUnit Voltage Display Range: 0.50 - 4.49VTotal Voltage Display Range: 0.50 - 25.9V1S Test Mode Voltage Range: 3.3 - 13.2V1S Test Mode Detection Precision: + or - 0.5%Low Voltage Buzzer Alarm Mode for 2-6S
