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!
The amount of current you draw should be super low, even for 1C batteries so the produced heat should be negligible. I would however leave some space for potential puffing and maybe somehow a small window to check (if possible)
1-2mm would be fine. if you don’t have such space, i’d personally do it but i wouldn’t recommend it
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 <C rating> times <battery mah rating>”. 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
I always leave the battery with some space around it. You never know when it starts to vent. Also wrapping around battery decreases airflow, I know that the current in this cases is not big and battery should probably never heat up, but I’m just careful with batteries.
