Hi and welcome to FixYa,
Initially, pls try recharging the battery again. Remove the connector to the voltage regulator. Start/run the bike. If it lasts more than "3-5 minutes" then you have just confirmed a defective regulator. The voltage regulator would look something like below image.
This page may give you additional insight.
Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.

You need new regulator and new battery.The battery works as a filter as well.If it is in bad condition it does not filter anything and in high rpm the current is very high.

Your calipers are getting hung up because they are over heating. you could have to much fluid in the system, and it is not letting the pistons back into the caliper. You can rebuild the calipers or try to drain and bleed your brakes over again it might work it might not
