It takes all night, but after a few cycles mine did not charge fully anymore, checked the voltage readings and saw that the cells were unbalanced by almost .3V so I would not put to much faith in the internal charger
Yes they are fully charged, but those readings are from the mod itself and like @BubiSparks said the RX200 isnt very accurate with these things. So I will check on that when I am back home, hopefully I get a full charge.
I got the external charger and it is much better now, reading 4.21, 4.20 and 4.17 on the mod itself. Will check on a multimeter when I am back home, for now I am enjoying Ballito for a bit:D
Thanks for the help everyone!
