A PK battle (from "player kill", inherited from gaming) is TikTok LIVE’s head-to-head mode: two creators split the screen, and for a timed round their audiences compete by sending gifts. Each side’s score is the diamond tally its audience produced during the round — highest score when the timer hits zero wins, and the loser typically pays a forfeit on camera.
Battles are the highest-intensity earning moments on TikTok LIVE. A room that idles at 5k diamonds an hour can move 50k in a ten-minute battle, because gifting becomes competitive and public — whales fight for the top-donor slot, and the FINAL STRETCH seconds decide most close rounds.
TikRadar tracks the battle as a first-class object: the live score per side with per-second deltas, the countdown, a win-split bar, and — the operator view — the TOP DONORS panel that breaks each side down donor by donor, with their PK points, share, and the exact gifts they sent. Finished rounds archive into Past battles, and repeated matchups build a head-to-head record between the two creators.
One honest mechanic to know: TikRadar reads battles from the rooms it captures. If the opponent’s room is not publicly tracked, the opponent column only shows gifts that your side’s audience explicitly tagged to them — so their displayed total can undercount their real one. The console says so right in the panel, and a + MONITOR button lets you start tracking the opponent to get their full side.
