Question about the max. Voltage

Hello, I have an Orbit 2 and I want to use my emergency charger if I´m for longer time outside. I used the charger before for my TH55. Now I changed the plug to connect it to the Orbit 2 and build in a diode that the voltage is about 5.3V. Does anyone know, is it possible to connect without problems the charger without any diode to the Orbit 2? For this it would be about 6V (with fresh batteres). If the current flows I think there is less than 6V, because the internal resistance of the batteries.
With the diode it works, but without I would have more capacity.
Thanks for you answers!

ok try to sync your uni with computer and see if it syncs... if not your usb port may be broken... if it does then that might be issue with battery... try another battery and see...
I assume from your description that the battery is completely dead?
The led will blink red if there is not enough charge to power on the device.
If the battery is this dead, the device will not charge it.
You will need to use a seperate charger to charge the battery enough for the bootloader to initialise.
The device can only charge your battery if it has a small amount of charge already.
It can not charge a completely drained battery.
