东帝夜视DAKINGNV-DKGPNVG18四目全景高清微光夜视仪

产品简介Product Introduction：

夜视仪主机挂架上配有电池(可选），辅助供电的电池盒（可选），通过标准DC电缆与主机相连。它配有一个可用四个2.8-4.2伏CR123A电池的电池组，这些电池可以为该装置供电大约50-80小时（不开IR的情况下）。远程电池组不但可以为主机供电，还作为配重提供辅助功能。

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.
