The APM 2.5 Power Module is a simple way of providing your APM 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. Another signal cable connectors are used in Japan original fittings, non-domestic joint,so APM flight control board and reliable connection between the power supply module. The Power Module comes completely assembled with XT60 connectors, and wrapped in shrink tubing for protection. Voltage and current measurement configured for 5V ADC6-pos JST SH1.0 cable plugs directly to mini APM PM connectorSuitable for: remote control aircraft Specifications:Max input voltage: 25V Max current sensing: 90A Size: 25 x 20 x 10mm/1 x 0.8 x 0.4 inch Delivery size: approx. 92 x 145 x 15mm/3.6 x 5.7 x 0.6 inch Net weight: 29g Package included:1 x Power Module Note:The Power Module is only designed to power APM, a RC receiver and APM accessories (GPS, 3DR radio). It is not designed to power servos.Use your aircraft's own ESC/BEC
