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.

Thanks, yeah I was thinking along those lines and I'd rather be safe than sorry.
It'll be fine. Keyboards without any lights use very little power so the battery won't get warm during use.
The keyboard I'm modding has RGB, so I guess I should cut around it?
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!
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
Love all the helpful advice on Lemmy, thank you!
