Hello.
Am I in over my head on this one? Would really appreciate someones help!
Let me explain as best as I can. Learning as I go..
I am wanting to power my video camera and video monitor from one single battery that I have (Rolux Li-on 14.8V 8.8ah 130Wh)
I have a a few batteries that came with the camera and a few that came with the monitor.
(Camera: sony a7s - battery "7.2V 7.7Wh(1080 mAh) min 7.3Wh(1020 mAh)"
(Video Monitor: SmallHD 501 - LP E6 Battery "7.2V 1300mAh 9.4Wh"
I have a "Dummy Battery" for each device. My current set up is that I run the dummy batteries through a battery bank (2 battery banks, one for camera.. one for monitor)
Battery bank = XT-Power 10000mAh/37Wh Output: DC 9V/12V (you can switch)
I have always run my Camera dummy battery (no voltage regulation) through the 9V dummy battery.. no problems..
I have now purchased from ebay mini 360 DC-DC buck converters (specs at bottom) and ran one inside my monitors dummy battery (multimeter says the dummy battery/monitor is getting 7.8 volts)
Run through the XT-Power battery bank at 9V the monitor runs perfectly fine.. but when switched setting to 12V the monitor shuts down after a minute..
I am guessing the buck converter is getting too hot and cant handle it and shuts down? unable to find out how hot.. but when power is running through the buck converter gets very hot to the touch
My overall issue.. If the monitor cant handle the 12V running from the Power bank.. then i know that I will be unable to use my ideal power supply (the Rolux 14.8V 8.8ah 130Wh Battery)
Is this Buck converter just not the tool for the job? seems as though..
Looking forward to help on this!
