Foam mod and battery - can I cover the battery? (discuss.tchncs.de)

As the title says, I was wondering if there's any concerns regarding the battery life or fire hazard if I cover the battery with foam? Should I cut the foam to fit around the battery? I've seen people do both online.

I have some denser, rubber like foam as well as a more fluffy one, looking for deeper sound. TIA!

how many hours does the battery last?

continuing my above answer: your cell should be a cheap 1C (which is just cheaper than the 3+C, not bad, it’s totally fine for your application) The C rating means “the max amperage you can draw from the battery to be safe is times ”. So a 1C 2000mAh battery has max amp draw of 2A (or 2000mA) while a 2C 500mAh has 1A (2x500mA)

If your battery lasts for more than 10 hours straight that means you draw 1/10th of max amp - meaning a cool battery. In case of a 1C 2000mAh you draw 200mA

So: if your keeb lasts more than 10-15 hours you’re more probably fine as the battery is kept cool

Wow, thanks for the thorough explanation! I have a Keychron K2 V2, so it should be 4000mAh as per the website.

pffft there’s no way you draw even near enough battery to even notice any temperature change

Cool thanks for easing my mind!
