Battery ? Why so hard to find the right one ?

  • Hi,


    I really struggle to find a decent battery that would make the robot running for a couple of hours


    I have RPI4 run ROS2/slam using a LIDAR and 9V lego technic XL motors with an mc33926 pololu H bridge and I use buck or boost boards to deliver enough voltage/current


    the RPI itself is power cycling if the battery is not delivering enough


    I found a couple of power banks but I believe it will make the robot run for an hour at best


    any tips on that ?


    thanks for your help
