DPSI RV series - in general The voltage for the receiver AND the servos is regulated at a constant value for the first time in this new range of products. The problems that arise with traditional fully loaded 5-cell batteries are therefore eliminated. The entire receiver station is now supplied with stable voltage, which the user can adjust via jumper to a range of 4.8 to 6.0 volts. Thus allowance is made for every type of application.
For the first time, a micro-controller is integrated into the DPSI RV, which monitors the battery voltages by means of an intelligent algorithm. When the battery (or batteries) is/are 60-70% discharged, this status is acoustically announced by a built-in buzzer. This rules out the risk of empty batteries. There is always enough reserve to complete a flight and then charge the batteries.
The generous dimensions of the cooling surfaces and the voltage control now make it possible to use new battery technology such as lithium-ion or lithium-polymer cells. These extremely light cells have an energy density up to 400% greater than NiCd cells, for example. This means: high capacity with low weight. The LONGGO batteries are the premium product among the lithium-polymer power sources. Two selected and matched lithium-polymer cells are each assembled on a high performance receiver battery, which is available in four different capacities. 1200 milli amps/h at 2.1 oz(60g) weight, 1500 milli amps/h at 3 oz (85grams), 2000 milli amps/h at 4.3 oz (122grams) and 3300 milli amps/h at 5.8 oz (167 grams). These batteries can withstand currents of up to 20 amps. With parallel connection of two battery packs by means of the DPSI-RV, peak currents of up to 40 amps are possible without any problems, without the voltage breaking down.
