XBERSTAR 10pcs 3240 Epoxy Board FR-4 for DIY Battery Pack 20.3cm*17.2cm*0.05cm(10pcs Epoxy Board)

Can cut with scissors at 5mm. JBD plastic bonder holds it well. It's not cheap but nobody else seems to sell it so I guess I should be thankful they arent charging more than 1 buck per sheet. fairly heat resistant too, but delaminates if i hold a soldering iron against it. It still might be good for a workplace to protect a table though.

Good sale men and good products

A little pricey but if you think about it it's not too bad, where else are you going to get epoxy board for batteries with next day shipping? I was also surprised that this is the sturdy thick stuff, not the thin flaky stuff. It's the exact size for my 320 AH prismatic cells

So far they fit perfect for my type of cells. Would recommend.

These are actually a decent price and they work fine. They arrived quickly, and I had a hot job so I was able to get that out of the door on time thanks to the speedy Prime delivery. I’ve never seen any of these that are miles better (or worse) than the others. It’s a pretty standard material and if you’re building batteries you’ll want a pile of this on hand.

These are nice and good quality.
