So I am building a battery pack for an electric scooter using a bunch of rectangle lithium batteries, and I'm to the stage I need to sort out the cell separators.I planned to use g10 fr4 epoxy board but I designed one of the larger separators and the single piece would cost 38usd to have cut out and sent. I intended on having it all cut out and designed so that it slides all together but nope lol, it would cost like 300usd++ for that.So now I must use smaller pieces and somehow cut them myself and figure out how to join them together.Has anyone here done something like this? What's the least painful way to cut g10 with some level of accuracy?
>>2873797It's fiberglass. You can cut it with damn near anything. Carbon steel/HSS blades will dull fast, but they work. I've used a coping saw to cut out PCBs before, even.
>>2873797You can cut the thinner ones with scissors even. Exacto or any other knife will score it and you can snap it, or go over it multiple times and cut it. You don't need thick fiberglass for electrical isolation in batteries.
>>2873797Why that stuff?Seems expensive.You could just use silicone baking sheets to separate. Better heat/chemical resistance, too. Less rigid though. Doesn’t seem like you need the rigidity.
