I have a 2007 ETX90 and was thinking of getting an external Lithium Ion battery . I need to know what a good portable AH rating battery to get. Is 6 AH good enough or should I go double digit AH like 10 AH plus
I dont know the current Amp comsumption for the ETX90 SIDEREAL (tracking ) rate or the larger Amp needed for the SLEW rate. Does anybody know these 2 Amp parameters please?
I know the ETX AC adapter #547 is 12 v at 2.5 A and has a male plug 5.5 mm OUTSIDE DIAMETER and a 2.5 INSIDE DIAMETER. and the RED lead from the battery is plug CENTER PIN with a fuse. Should I put a fuse on the black lead also?. And what size fuse Amp to get and should it be a fast blow fuse or ???
Does the battery have to have a steady 12 volts output or is there some voltage variation acceptance . I'm afraid anything under 12 volts going into the scopes circuit board may damage it
Any ideas would be appreciated
