I'm building my first e-bike. I bought the 1000w Yescom kit with the LCD screen and a V-Power 48v 10ah battery. Plan on only having the V-power a couple months then will upgrade it. I measured the battery output and it 49.6v. As soon as I hit the power button on the LCD the screen flashes on for a second and then the voltage drops to 13v and then will slowly climb back up. I have measured the battery not hooked up to the bike and it holds steady at 49.6. I have not clue what to do, help.
