## Description

desertcart.com: XBERSTAR 10pcs 3240 Epoxy Board FR-4 for DIY Battery Pack 20.3cm*17.2cm*0.05cm(10pcs Epoxy Board) : Industrial & Scientific

Review: Thin, tough 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.

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
