Re: [Elecraft] Concerning Bioenno LiFePO4 Connectors

2017-07-26 Thread Bill Frantz 
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.

Re: [Elecraft] Concerning Bioenno LiFePO4 Connectors

2017-07-26 Thread Clay Autery 
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, programmable choice). 
With a recover to charge switch back when load (chosen) is once again
absent.  (Need a battery recover delay PRIOR to switch on to allow it to
stabilize BEFORE the charge circuitry starts sending to set voltage/current.
Probably NOT "needed", but I like to be "nice" to my batteries and I
like to be even "nicer" to my radio.  I want it to get PURE,
unadulterated DC.
But I am the weird guy...  I get that.

Re: [Elecraft] Concerning Bioenno LiFePO4 Connectors

2017-07-26 Thread Don Wilhelm 

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 have that spec.

On our PVC Pack LiFePO4 batteries, there are two separate connectors.  The
first connector has a DC barrel plug and the second connector has an
Anderson Powerpole connector.  The two connectors are indeed wired in
parallel on the PCM (protection circuit module) that is integrated in every
single battery pack.  So it is perfectly okay and fine to charge through
the PowerPole connectors. Many customers requested two separate connectors
in the batteries, in order to keep the battery's charger attached to the
battery, such that the battery and charger can be stored in a portable
Go-Box.  At the same time, customers can leave the PowerPole connector
attached to the radio communications equipment, without having to
repeatedly disconnect the charger from the battery, and attach the radio
communications equipment.  However, we understand customers want to charge
through the Powerpole connectors and use various other third party
products.  We provided the two sets of connectors, simply for convenience
purposes.

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 combining charge and discharge
makes more sense. I've run the PWRGate here with a marine battery for a
while. I could see tucking away a similar product for the LiFe batteries
into a go box.

The chargers I have I bought with the batteries. I leave them plugged in
and charging all the time ready for hitting the road.
