12v 3s Battery packs for Ham Radio PT2

This was posted as a reply to my 1st post. I thought I should starta new Thread with this question.

Thanks to all who replied.
Glad to see Ham's also.
Here's what I'm looking at also with a few extra 18650's I've collected.
Worked out in:https://www.repackr.com/#/pack-builder
3s9p
pk. 1 pk. 2 pk. 3
2200 2200 2200
2200 2200 2200
1921 1914 1939
1833 1839 1927
1825 1833 1775
1776 1783 1761
1765 1769 1748
1763 1741 1739
1736 1740 1730
17.019Ah 188.91Wh
This is to be used with my QRP (Low Power) radio, in CW mode(Morse Code)
Its a KX 2
1600 mAh draw key down (Transmit) and 160 mAh draw key up (Receive).
I figure 20 minutes ON and 40 minutes OFF per hour average.
Does anyone see any problems with this? I am new at this so help would be appreciated.

as long as the radio can operate at the lower voltages down to about 9 volts it should be good. But if you have problems once the battery gets at lower voltage a boost/buck converter will help.
This is the boost/buck converter I use to power my 12 volt fridge that has problems operating with my 3s battery. With this converter the fridge will work until the bms shuts the battery down. This converter produces very stable power with only a .2 volt voltage drop when outputting 6 amps.
