Recommended battery


I've purchased UP Xtreme i11 and I'd like to buy a battery for it. On the website I found the information, that recommended battery for this robot is this power bank, but there is a problem - it has only one DC output, and I also need to power the Motor Cotnrol Board. I know that there are also additional USB outputs, but they do not have a proper DC connector. What is the recommended solution to this problem? Should I buy 2 power banks, buy additional LiPo for Motor Cotnrol Board, or do something else?

Btw. I also have UP Squared 6000, please let me know if the proposed solution works also for the second robot.
