Probably too late to comment here, but I love the battery of Sena B20. Used for a full ride during QCM, and after almost 14 hrs it was still at 35%. For most of the time it was connected to bluetooth as well (though was not using music streaming)
Also if you pickup this devices from PowerSports, Hyderabad in person, then they provide extra 5% discount
@sajeesh Torque Block is really a good option for picking up tyres. I picked up my Karoo Street from them about 8 months back. Hassle Free experience and they first understand your riding style and need & accordingly suggest the best in the segment tyres for your required purpose.
