Go with LiFePO4 cells. Four cells will keep the voltage between 12 and 14.4 V from 10% to 100% state of charge and most of the time the voltage is between 13 and 13.5 V. I use small ones (3 AH )for backpack portable operation, 20 AH for fixed portable and my RV has 400 Ah to run the rig forever!

I have looked at the power issue (even though I'm not yet a KX3 owner) and with NiMH cells at 1.2 V, the 8 cell internal battery holder would only be 9.6 V. I'm considering an external battery pack with (2) 6 cell holders for 12 cells total. That would be 14.4 V total. A single series diode

Hi Chris I use LiFePo4 batteries The voltage is higher and I can transmit higher power for example 15 watts. Bioenopower makes some nice ones. Good luck Richard __ Elecraft mailing list Home:

Yes sir using 7AH gel cell. Just found out the issue as it works to 15W on a bench supply so the issue was pointed out to me by a kind list member that this is intentional limiting while on lower capacity batteries. Chris > On Jun 22, 2019, at 1:16 PM, Scott Manthe wrote: > > Are you using
