That seals it... HAM "quiet" charging/operation system is definitely on the list now.
I bought the little 2A charger to get me by with my little 12 Ah batt for use with RFI/noise hunting for now. But I'm going to start reading/researching and putting together a requirements list for a "proper" charging/operating system for the LiFePO batts. I like the idea/concept of the PowerGate, RigRunner, etc... And it would be nice to have a system that could run from a large cap LFP and still charge... while during non-op periods could charge to capacity and thence complete the cell balancing... (I'm assuming that is how it works generally). Time to learn something new... :-) As an aside... Jim, I think I read in one of the Bioenno batt docs that the output voltage is somewhere around 12.8 VDC... so it is "closer" to nominal... A "nice to have feature" in a system WOULD be to be able to find a way to "boost" the voltage to 13.8+ to realize the lower full power IMD, WHILE simultaneously keeping the power system "quiet". Not a priority right now. ______________________ Clay Autery, KY5G MONTAC Enterprises (318) 518-1389 On 7/11/2016 4:55 PM, Jim Brown wrote: > On Mon,7/11/2016 1:49 PM, Marc Veeneman via Elecraft wrote: >> But beware the charger RFI.
