Let me have a look at the Forum settings, I can’t say I remember this by heart 
EDIT. Indeed, these are hard limits So silly!
I found this request on meta.discourse.org, which didn’t get any traction so far:
Daily-limit mode for Voting Plugin - feature - Discourse Meta
In the meantime, I increased the limits by adding a few 0’s, more to the higher trust level accounts:
