Hello, would leaving the projector connecting to the charger damaga the battert? I find it easier this way so i don’t have to connect it every 3 hours… what do you think?
No it can’t do any damage.
If anything, it will lower natural wear’n’tear.
But, every few months (say 3 times a year) let it fully discharge from full. Don’t do that any more often as it will then do the opposite accelerate wear.
So keeping it plugged in when you don’t need battery, and then let it discharge fully every few months, will do the least harm overall.
Just leave it as is
