Hi Mate I have similar setup to you. Just purchased EVE 304 cells. Block of 16 cells. Two rows side by side. How did you compress them? I have two pieces of timber at both ends with 4 threaded rods, two on each side. with the yellow plastic sheets inbetween. What should I tighten the small threaded rods tood? I cant figure out the psi. Thanks so much.

Georgia Stephen , Question - all the heater pads I looked at shut off at 60F that is too warm in my opinion.
Are you sure the temp range on your RV heater pads? sounds perfect 40-42 F. I would like to get some, if you remember what brand and where they came from. Nevada & Tahoe gets very cold winters.

Do you think you will be reviewing the delta pro ultra? I currently have the eg4 18k setup for my off grid but looking for a more a plug and play. Seen the promotions and I am excited for it. Especially since the delta pro has been great for my off road rig.
