Turn on TK1 using a battery

hi,

I need to turn on TK1 by using a battery, so after searching I have found this:

I have bought a 2200 mAH 11.1V 45C 3S Lipo Battery to connect it with jetson tk1. the battery is fully charged, but once connecting it to the jetson, JTK1 doesn’t turn on. what to do in this case?

Regards,

Power via battery or adapter should ot change anything. Sometimes the supercap means you have to hit the “on” button manually (Jetson may not power up just from plugging it in). What voltage do you measure on the connecting plug?
