From my bench test of my new LiFePo4 30 ah battery and 10 amp LiFePo4 charger (above) to installation, was my job for the day.
I first needed to remove the multi chemistry sealed lead acid battery charger and 3 12 volt 8 amp hour batteries below.
I prepared the LiFePo4 battery with 2 conductor quick connect that is fused. I used these quick connects in my previous house battery versions for ease of assembly and upgrades.
I wanted to protect the terminals on my LiFePo4 battery so I used PVC wood, that I use in many of my projects. I used 1/2" PVC for two layers. I drilled out the first layer to accommodate the battery terminals and wires so it would lay flat. I then added a smaller piece to cover the top of the terminals that were flush to the top after drilling and laying on top. I glued the top piece on with PVC glue.
The picture above shows the drilled shoulder holes with routings for wires.
I attached the PVC protection with 2 Velcro buttons.
I cut the plastic to size and put a radius on the corners to match the size of the battery.
The rear storage hole in the rear driver's side of the Prius is not flat and as it turns out the 1" of PVC I added was just right to fill the void allowing the battery to lay flat with terminals down.
Next I needed to hold down the new LiFePo4 10 amp charger in place of the other charger, behind my dropdown panel. I chose to use aluminum vinyl siding starter as this is what was available in my garage. I bent it and made flanges that screw down to my plywood base.
