This handy little voltage meter is compatible for use with Lipo, LiFe, Li-Ion, as well as NiMH and NiCd batteries. The Sentry 4 shows at a glance the remaining capacity in your LiPo battery pack, cell balance, cell voltages and difference between cells. A unique feature of the Sentry 4 is it's Stand-alone Balance and Discharge Mode for Lithium batteries which is convenient for storing fully-charged packs down to 3.8v. Furthermore, the Sentry 4 also boasts a Servo and ESC tester by connecting a external power supply you can control and test the Servos frequency, Servo test range and ESC settings.

    WARNING: Do not keep your battery connected to the Sentry4 for long periods of time. Since this unit is powered from battery source, the parasitic draw while on standby will consume your battery, thus your battery will over-discharge. Once discharged and stored, disconnect the Sentry 4.

    For Servo & ESC tester function, we suggest to use with 1000 - 2000 pulse setting. Also please set frequency value at 50Hz if you are not sure your servo's specific frequency.

    Estimated remaining capacity percentage "%" is only a guide so please judge by remaining voltage.
