Billy Kee hit a hat-trick as Burton saw off Barnet in a pulsating contest.
Kee smashed home a Kevin Amankwaah cross before notching his second with a fine individual effort.
The hosts pulled themselves level thanks to strikes from Izale McLeod and Ricky Holmes only for Kee to get his hat-trick with a fierce shot.
Subs Adi Yussuf and Jack Dyer extended Burton's lead before a late exchange of goals saw Sam Deering net for Barnet and Calvin Zola bag for the Brewers.
VIEWS FROM THE DRESSING ROOM
Barnet boss Lawrie Sanchez told BBC London 94.9:
"That defending isn't good enough for League Two. I can't find two in the centre-half positions that work. New players need to be brought in.
"If I was a fan I would be shouting the same. I'm ultimately responsible for that shambles and that is a performance today that a lot of clubs change managers on.
"I've inherited the rest of this squad, so whoever comes in or whatever happens the personnel needs changing, but i'd like to think the chairman thinks I can be the man for the job."
Burton Albion boss Paul Peschisolido told BBC Radio Derby:
"It was a bit of a thriller wasn't it? We certainly provide the excitement factor, that's for sure.
"Offensively we were fantastic, we looked like we were going to score every time we got into their half. I thought our front players were absolutely magnificent whoever they were, but defensively we weren't at our best.
"I can forgive them for a bit of an off day today, because the forwards got them out of trouble."
