Mikhail Gordeichuk put BATE ahead in the second minute only for Admir Mehmedi to equalise for the German visitors, with the result leaving Barca five points clear of third-placed Bayer, who have only a single match left, in Group E.
Luis Enrique's side entertain Roma at the Camp Nou later on Tuesday knowing just a draw will ensure that they go through as group winners.
At St Petersburg, Russian champions Zenit St Petersburg extended their winning streak in the Champions League to five games with a 2-0 win over Spanish high-flyers Valencia.
Goals by Oleg Shatov and Artem Dzyuba ensured the Saint Petersburg outfit, who had already qualified for the knock-out rounds, will top Group H.
"We started with very good intensity giving Valencia no chances to play their normal game," Zenit manager Andre Villas-Boas said.
"Apart from 10 minutes in the second half we dominated the play completely, created lot of chances and, I believe, deserved to take the win.
"It's a very good moment for Russian football and a deserved top-place qulifying for Zenit."
Valencia could have gone through with a win but will instead drop to third place if Belgian champions Gent win at Lyon later on Tuesday.
Lyon, bottom of the group with one point, also remain in contention and know that a win against Gent and another victory in Valencia next month will see them advance.
Elsewhere, Bayern Munich and Olympiakos will both secure progress from Group F, and thereby eliminate Arsenal and Dinamo Zagreb, by drawing in Germany.
In Group G, Porto can clinch their place in the last 16 with a win at home to Dynamo Kiev while Chelsea could also guarantee their progress when they take on Maccabi Tel Aviv in Israel.
Real Madrid and Manchester City, who play on Wednesday, are already through to the knockout stage.
