Sorry for my drawings.
I'm trying to supply my monitor, Googles, video splitter and video receiver mainly (plus other little things). I have some regulators, but their mA are little behind, so I thought if I put them in parallel I might get away with it.
I would like to reduce my ground station to a simple 12v LiPo Battery and do several step down to get all the voltages needed
I'm not going to charge any battery, just power up gear from one battery that will be main power supply
