[Elecraft] Concerning Bioenno LiFePO4 Connectors

[Erik Tkal]

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 radio tries to draw too much?

  Thanks and 73,

I asked Bioenno about the  use of the connectors and pointed out their site
shows the barrel is for charging and the Powerpoles are for discharging. I
was told this is not correct and that they will fix the information on
their site. They have a process to go through with their product people so
it won't happen quickly. However, they did update their FAQ section:

*LFP:  Why is there a separate DC barrel plug connector and PowerPole
Connector on my battery?  Can I charge through either connector? *

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.
