產品簡介Product Introduction：

夜視儀主機掛架上配有電池(可選），輔助供電的電池盒（可選），通過標準DC電纜與主機相連。它配有一個可用四個2.8-4.2伏CR123A電池的電池組，這些電池可以為該裝置供電大約50-80小時（不開IR的情況下）。遠程電池組不但可以為主機供電，還作為配重提供輔助功能。

The night vision instrument host is equipped with a battery (optional) on the rack, and an auxiliary power supply battery box (optional) is connected to the host through a standard DC cable. It is equipped with a battery pack that can accommodate four 2.8-4.2 volt CR123A batteries, which can power the device for approximately 50-80 hours (without turning on IR). Remote battery packs not only provide power to the host, but also serve as auxiliary functions for counterweights.
