First of all, hello Community!

I'm new to the Saber Scene and also this Forum, and I have some questions regarding the replica I am currently using. It wasnt built by me, but by a German Sabersmith called Argentumsabers. Anyway, I need some info regarding the parts (and whether I have unrealistic expectations about them or not). First of all, the stats. It works properly (meaning no abnormal behaviour while normal usage) but has some... Issues.
As far as I know it runs a Red TriCree LED with white FoC and a Nano Biscotte V3 Soundboard with 2 fonts. My problem is, that the saber starts making swing noises without any input (which is a sign of a low battery, as far as I know) after a bit more than an hour of literally just laying around. (So no FoC triggers, nothing. I literally just turned it on and put it on the floor to wait.) Is that a normal battery expectancy for a saber with a charge port & activated sound?
Besides that, the constant swing noises get really annoying, cause the blade doesnt get dimmer and even continues to work for more than 30 min so the "warning" starts way too early. Is there a way to somehow fix that?
Oh and also I have some general beginner Questions:

Does swinging/FoC triggering OR switching it off/on often actually influence the battery life?

Could I theoretically just delete the swing sounds from the card to make these annoying noises stop?

As a beginner with no mechanical or technical knowledge of saber construction in any way, how could I extend my sabers battery life using the config on the SD card?

I beg for your help experienced members, since I'm gonna attend a con in less than a week and would really fancy to fix that damn thing inbefore.

Greetings,

Luka
