Glenn Maxwell has credited an extended run of games with the Melbourne Stars in this summer's KFC BBL for his match-winning century in Bengaluru.

Maxwell blasted 113no overnight, his third T20 international hundred, to guide his side to an epic seven-wicket win that sealed Australia's maiden T20 series triumph over India.

His stunning knock backed up the crucial 56 he made in the series-opener in Vizag on Sunday, and the Victorian says his consistent diet of T20 cricket in the Big Bash primed him for the series.

"I was actually quite calm for most of it," Maxwell said.

"Playing the Big Bash before gave me a bit of confidence coming to this tour.

"I've been batting at four for the Stars, I'm familiar with my role. I've been coming in at two down in the T20 side for the last 12 months, it's a consistent role for me.

"I think once I get that consistency of role, you can actually start to see consistency of performances.

"And I think that's probably what has led to this."

Maxwell normally misses large portions of the Big Bash due to international duty, but this season played 13 games as skipper of the BBL|08 runners-up and started to find his feet at the back-end of the tournament with scores of 61, 5, 82, 43no and 1 in his last five innings of the competition.

His good form was checked-in with him on the flight to India, where he's faced difficult situations on both occasions he's walked to the crease.

In Vizag, Maxwell entered at 2-5 and on Wednesday night he found himself in a similar predicament at 2-22 with his side needing 169 runs to win from 96 balls.

Maxwell rued getting out in the first match - his dismissal sparked a chaotic collapse that almost cost Australia the match - and said he wanted to build on those starts to the point where he sees his side safely to the victory target.

And he did just that in the second match with two valuable partnerships; a 73-run stand with D'Arcy Short and, when the left-hander departed in the 12th over, an unbeaten 99-run partnership with Peter Handscomb, who finished 20 not out from 18 balls.

"After D'Arcy's dismissal it was up to me to really stick around and drive the rest of the innings going forward," said Maxwell, who is now the only Australian with three T20I centuries.

"Pete Handscomb did a really good job of getting off strike and being really busy.

"We were able to build a partnership really quickly and we didn't really lose too much momentum after that wicket.

"I thought that was a really key moment of the game. Last game we had that run out and all of a sudden a bit of chaos at the back end. But we were able to keep consistently having good overs and keep that run rate in check."

Maxwell's century celebration was muted by his standards, saying the point to his bat when he reached 50 was a nod to a very special piece of willow.

"I've been saying in the changerooms I've got the best bat ever," he said.

"It’s being held together by tape at the moment. The inside edge has been pretty badly hammered.

"There was a bit of it coming off in the third-last over and they told me just to change it and I was like 'nah, I'm not changing this bat, it's the best bat ever'.

"I was just showing the boys that I meant it when I said it."
