4 Position Power Distribution Block for 15/30/45A Powerpole Connectors

I ordered the PowerWerx PD4 with the idea that I could connect two LiFePo4 batteries in parallel and power amateur radio devices with the benefit of the combined amp/hour rating of the two batteries.  I added the PowerWerx battery capacity meter to verify/monitor voltage and state of charge.
I attached Anderson PowerPole connectors to two 12V/40Ah LiFePo4 batteries,  My first step was to connect one battery to the meter to check voltage and state of charge.  Then I disconnected and attached the meter to the next battery.  With the batteries showing a proper output and state of charge, I connected both to the PD4 and attached the meter.  It showed a proper voltage for a parallel connection, so the batteries appear to be connected in parallel.
I've attached the charger to the PD4 to charge both batteries simultaneously.  When I had charged the batteries for an hour or more, I checked to see if there was a change in the state of charge in each battery.  It was a short charging period, so there was not a substantial change, but it does appear each battery benefitted from the parallel connection to the charger.  I didn't want to leave it connected when I wasn't present to monitor the whole thing, so I stopped the charge and disconnected everything.  It is now reconnected and charging.  
The PD4 should give me the option to configure a mobile/portable set up with one battery, the meter, and multiple devices.  Or, I could connect two batteries and a device for prolonged operation.  
As an amateur radio operator, this seems like a decent emergency power set up.  If I attach my portable solar panel and solar controller, it could help maintain some battery charge while using the station.  That set up would likely only slow the depletion of the battery(ies), not maintain a full charge, based on the current draw from the radio.
Another set up I have in mind is to put one of the larger capacity batteries (40 Ah) in the car and connect it to a mobile radio and the appropriate car charger.  This would avoid putting any strain on the car battery, especially when operating with the engine turned off.  (Note that with LiFePo4 batteries, the charger must match the battery chemistry.)
I'm very pleased with the PD4 thus far.  It is a bit expensive for what it is, but the alternative would involve a lot of wiring and patch cords.  The PD4 makes it a clean connection that can be easily broken down while the gear is relocated and then reconnected quickly and easily without the need for a lot of additional cords and connectors.  Each battery, the meter, the radio(s), and charger all have Anderson PowerPole connectors attached, so everything comes together without a single extra cord or cable.

The focus of the description and reviews is one power source in and three devices out.  If two power sources were attached (eg. two batteries), would they "appear" in parallel to power two devices?  The idea is two LiFePo4 40Ah batteries for basically 80Ah capacity.  For a long run - Field Day, for instance - there wouldn't be a need to change batteries.  Then, disconnect the devices (radios) and attach a charger to charge both batteries.  
The other question is whether one input could be from the battery and another from the car charger or solar charger and then two devices connected to power out.
The idea here is a power box that can be in the car to power units while mobile and then moved to a portable site.  I'm thinking Amateur Radio public service where you might switch between mobile and temporary fixed site during an event.
I plan on ordering the distribution block, and I'll experiment with the configurations.

GREAT way to power 3, 12 VDC things...
Very solid construction and I like the way it surface mounts.

I Highly Recommend this!!

Use this distribution panel in my shack for testing purposes Easy in-and-out connecting. Works great. Seems very well made but perhaps slightly over priced I think.

Feeding one of these in my truck with Pos and Neg fused 8 gauge stranded.  Using the 45 amp PowerPoles which just fit 10 gauge.  Block feeds a 300 watt 2 meter amp, an FT-991A all mode radio, plus a Radar Detector. Works great, clean install.

Wanted to add a Power Pole output connection to the back of my new Samlex 1223, using minimum cabinet modifications.  Attached the PD-4 with two small screws.  Connected one cable pair to the 12V output lugs, leaving three pairs for attaching radios.  "Voilà!"  Thanks Powerwerx.

Great size, very solid feeling. I was confused at first in terms of how my cables would it in and ALMOST started making new cables.

Your normal pre-made cables will work, but in a 2 by 2 configuration (I was was thinking a 1x4  top-down configuration at first)

Keep rotating your cable until they slide on the red and black Powerpoles.

This is a nice practical design, with the bonus of being able to mount it.
