I have a 200mw vTX could I use a 350mah or 500mah?
Any help would be appreciated?
Where so you mount the battery on the scarab?
I use either 5.8Ghz/200mW or 900Mhz/500mW transmitters from the website where I purchased them (hobbywireless), I got the the have a power consumption of 160mAh and 450mAh. Do not forget to check if your Osd can be powered by the 4S or needs also to be powered by the 3S too. Theoretically, your 350 mAh battery could power your 200mW transmitter for more than one hour. To be safe, monitor this battery voltage either with the Quanum or with your OSD, both systems can monitor more than one battery at a time. Where to mount it? Many places: next to your main battery, in my case it's under the scarab, you could place it between the mainframes if it's a quadocta, close to the video tx, or on top of the frames...
