12v from 4S for 5.8ghz tx

[steve fh]

I';ve got a 5.8ghz TX on order and just realised it operates on 7 to 12v which is an issue as i use 4s lipos

So what are my options for 12v ?  preferably from a UK supplier to keep lead time short.

I';m assuming i need a 12v output BEC and something to clean the output up?

TBS core does everything but seems like crazy money

this';ll step down upto 6s to 12v;) does that even make sense?!?!lol

It only works upto 5s on lipo';s

Input: 12V-23V (2-5S Lipoly, 2-6S Li-Fe or 5-15S NiXX Battery Pack)

theres the balance plug option-cons itll prob unbalance your lipo?
or just use a small 3 cell to power it..

Thanks.

Think I';ll probably go the small 3S route for a quick fix and order up a 12V bec from Hobby King once i get the set up finalised.

It';s only for viewfinder on a gimbal camera used line of sight rather than full fpv so no real issues if the 3S went flat in flight
