As a difference to previous NMP Battery Interfaces, BTEMP has been removed and battery
temperature is estimated by measurement in Transceiver PWB with a separate NTC resistor.
Thus the Battery Interface has only 3 contacts. BSI ranges has been altered and Battery Inter-
face will not support NiMh batteries.
