potential in LEO

I wanted to know what is the potential that the suface of the spacecraft will be charged approximately in a height of 600 km (LEO)? Because i have performed a simulation and i have obtained very low values on the surface (-2.54 volts in 1000seg. with eclipse) compared with a GEO environment and i wanted to know if it is correct.

Another thing, what is the predominant population of ion and electrons in LEO, cold or hot?

Best regards,
