Hello I have tried to figure out wich battery charger or power supply I should buy to be able to do coding but there don't seem to be any recent thread about it.

What should I look for? Would any high amperage >20A charger work?

Or would a regulated DC voltage lab power supply 20A bought from e-bay be better?
If I use a power supply should I set it to 14 or 12 volts?

For coding, I just keep the motor running,

For flashing, I use the Schumacher INC-700A 4/20/70 Amp Automatic Charger:

If you use the schumacer like a dc supply what voltage do you set it too?

btw Do you know any other good charger that I can get here in Europe for a good price without paying high shipment?

Do you think that a cheaper high amp charger would work just fine or a cheaper lab dc supply with 20-30 amps?

I set it in the FLASH REPROGRAM (Power Supply) Mode and use the defaults of 14.2 Volts. It can be varied from 13 to 14.8, but I just leave it alone.

All BMW states is maintain a minimum of 12.6 Volts during programming:

As for the charger, 20 Amps is no where near enough. In 2008 with the introduction of the E65, BMW was calling for a minimum 45 Amp charger as follows:

I am told now with Fxx cars it is a 70 Amp minimum, and ideally 100 Amp.

Sorry, but I don't know a good source for the European market.
