...as another AMT Netherlands convertee I can only echo the comments gone before - contact Bennie and quote your engine serial number (it is on the can where the main body joins the front cap and will start with NL....).
You will also be able to download the AMT Netherlands software (from their website) which will enable you to check the settings of your ECU. Here you will be able to see what battery voltage/type is required.
Enjoy the best model turbine in the world!!
