If you go to the battery with a multi meter, rev the bike to 2k revs = what voltage does it say? If you rev the bike at 5,000 revs , what voltage is it again?
2k Revs & 5K Revs are 2 tests , let us know what it says.
The battery is on you this time, it could mean time for a change, no size or brand was mentioned , so i will say go for YUASA (legit ones) or VARTA. Your caddy box is limited by physical dimensions , so a 14BS may be too big to slot in (that’s what us GTR / GT folk use)
So you may be limited by a 9BS -11BS type battery. New is still better than old, either way.
The more I read, the more likely its starvation involved too, & that we need to investigate the fueling side of things as i mentioned in previous reply as a checklist. Have you done either of those things?.
A final thing, pull out your spark plugs. Tell us if its “light brown, dark muddy brown, or jet black , wet black or glazed white” === pay attention to the CENTER WHITE TIP of the plug , otherwise you can attach an image if possible…. This is key also.
