GRAUPNER Lipo ontlaad-beschermer [GR6495]

The LiPo deep-discharge guard reliably protectsyour valuable LiPo battery cells from becomingdeep-discharged – which can easily ruin themcompletely. It is true that the speed controller monitorsthe voltage of the battery pack, but only the overall”voltage; if one cell is weaker than the others, and its”voltage is lower, the controller’s cut-off point may below enough to ruin the weakest cell. This is much morelikely if the pack contains more than three cells. Thiscircuit monitors each cell individually, and therebyreliably prevents deep-discharging. Using this circuitalso makes it safe to use any speed controller withLiPo batteries. The circuit is connected to the whitemulti-pin connector fitted as standard to GraupnerLiPo batteries, and it automatically detects the”connected cell count; it confirms this by a set of”flashing LEDs. The unit is also connected betweenthe receiver and the speed controller. If the voltageof the battery falls below a value of around 3 V percell, the circuit modifies the receiver signal so thatthe speed controller reduces the throttle setting tothe point where the 3 V minimum voltage is maintained.A jumper is fitted which enables the user to select aBEC receiver power supply where a BEC-equippedspeed controller is in use.
