I have some computer uses for charge and use at the same time. To keep it on topic, if the Elecraft radios had enough battery power to cleanly shutdown, then we wouldn't lose frequencies etc. when the power failed. It wouldn't take much battery either. 73 Bill AE6JV On 7/26/17 at 7:03 AM,

Lead Acid are charged/discharged at the same time in cars, but this is a different app... Ideally, I want my radio (load) to ONLY see the battery, NOT the charge current coming in. Ideally, I would like to have switching circuitry that cut the charge off while the load was present (idle OR xmit,

Erik, I think that all depends on the charger used and its characteristics. Chargers have a higher voltage than the cell(s) being charged. Elecraft gear is spec'ed for up to 15 volts, but make certain no part of the charging cycle will exceed that voltage - the charger manufacturer should

Hi Erik: I don't know the answer. I suspect you cannot charge and discharge at the same time. Bioenno's support has been pretty responsive so you might find an answer there. I believe Bioe is working on a product similar to the West Mountain PWRGate but specifically for LiFe batteries. Then

I wonder how operating a rig with the battery connected to the charger affects the charger operation? Does the charger perform the Constant Current charge and switch over to the trickle for LiFePo charging, or does the PCM manage that? Would there be any adverse effects to the charger if the
