How to power FPV transmitter with 4S Battery

[mshakeshaft]

Just a quick question. I have just moved to 4S batteries with my DJI F450. How are people powering their fatshark/immersion transmitters? I am using the ImmersionRC Fatshark 600mW 5.8GHz TX, which is rated at 6-21 volts. Are you using a separate battery? I was using the balance plug on 3S batteries but the filter is for 3S/2S cells is there a 4S version?

Thanks

Martin

Is there anyway to run something from the balance 4S connector? thanks

This is a 4S balance plug but only three cells are connected.

Why don't you just solder the power straight to the power distribution board? As you said above, ImmersionRC is rated for 4S.

Thanks for the reply. Is there a 4s filter? Or can I run the output directly from the balance plug. When I was doing this with the 3s battery I had a 2s/3s filter

Hmm. I can't remember how I powered mine as I've had it powered from the OSD for so long. On the S800 the Zenmuse powers it. Hopefully some else will chime in? Or Chris's solution looked handy and versatile.
