I built a new 14s10p pack and installed a ant 7s to 16s smart bms connected to my Android phone. It was reading 57.6v when I hooked up to my scooter. All was good but noticed no current amp and watt indication when accelerated so I stopped and on main screen press Current Zero and now have no power, no horn headlight nothing. Only other parameter I did on setup was set it to 14s.
I'm not sure if I turned key off when I press current zero. It's fitted with S886 LCD throttle. I put old full charge battery back in, still no good, you would not think it would blow controller, fuse OK,
Any ideas thought I ask before I stripped all my waterproof connections and recconect see if that works

You will have to troubleshoot and follow the power wires to see where the break is. Check to be sure you have battery output. Follow the wires for a possible inline fuse. If power is reaching the controller, you may have cooked it.
