16V into a KX3 would be terminal to the KX3!
I think you might need to refer to
http://kr7w-sota.blogspot.co.uk/2013/01/qrp-ops-battery-power-fyi.html
that has a few links. (Talking about FT817 but same issue of over voltage).
Or you could just buy a 14.4V LiPo or take one 3.7V cell out of the 4S
pack which will drop it to 13.7V?

p.s. For those not in the know... charging a 4S LiPo battery is not a
case of applying a voltage and leaving it like you would say a SLA you
need a proper LiPo charger. If trying to charge from 13.8V (I assume a
vehicle?) then look for an intelligent charger that will recharge LiPo
'packs'.
You can try and homebrew something but I wouldn't, ebay will usually
bring up plenty of options. Usually you would be able to pick up the
charger/charging electronics at the same time as buying the battery, if
the vendor does not have or cannot advise then be careful what you buy.

Hi All,
I have a KX3 and am doing some SOTA activations.
I have obtained a 4S LiPo battery which is somewhere north of 16 V with
full charge.
I would like to get a DC-DC regulator as a more elegany solution than
series diodes.
I have searched and searched but no solid outcomes.
Anyone have any input on where to find such a regulator?
Many Thanks,
Glen
