Bro what does your 12v 24ah Tracer battery run altogether iOptron CEM25P mount which cooled ccd and Mini-PC: Minix N42-C
and how long are you getting
Sorry for the late reply - the Tracer is running the CEM25P, Minix mini PC, ASI1600 mono cam + filter wheel, Lakeside autofocuser, mini travel wifi router, ASI120MM guide cam. This runs all night at least - for eg two nights ago I ran all this and only one bar of power had been used after 6 hours.
The dew heater/controller can draw 3Ah at 12V, so after 6 hours that could be 6x3 = 18Ah out of the 24Ah of the battery just for that. My separate 12V/6Ah battery only focused on dew heating lasts for about 5-6 hours, which either means the dew draw is higher than I said above or the cheapo li-ion battery is not delivering what it's rated for...my money is on the latter.
Anyway, you can try to run dew as well for the Tracer...but it might limit your imaging time. I recommend another source of power.
Hope this helps.
