The 2.5 Power Module is a simple way of providing your 2.5 with clean power from a LiPo battery as well as current consumption and battery voltage measurements, all through a 6-pos cable. The on-board switching regulator outputs 5.3V and a maximum of 2.25A from up to a 4S LiPo battery. The Power Module comes completely assembled with Deans connectors, and wrapped in shrink tubing for protection. Used to detect the battery voltage and the battery current, flight control board receives two signals, calculate the remaining battery power, estimate the remaining flight time. In addition the module also comes with BEC function, you can output 5.3 DC, 3A maximum continuous current for the flight control board to provide a stable power supply. flight control board and reliable connection between the power supply module. Max input voltage: 30V Max current sensing: 90A Colour:As shown Material:plastic Package Contents: 3 Module( Plug) 3 x P cable Only the above package content, other products are not included.
