I've been running my kit off a 27Ah deep cycle battery for a while now, but since I've started buying more gear that needs powering, I've reached a point where I'm running into issues.
Last night I spent maybe 30min-1hr adjusting alignment and sorting out some issues with plate solving. I got everything going and left it for an hour. When I came back, the last couple of frames had lines through them, PHD had totally lost my guide star and the power light on the mount was flashing. After packing up and getting home, I found got two frames before it went bad, so basically everything was running for no more than 1.5hrs before I had serious issues resulting first in banding in the images, then in serious issues tracking.
The battery was fully charged when I started the night. I'm running the NEQ6, SX Trius, Nautilus filter wheel (via Trius hub) and a dew heater strap. I'm running it all through a 4-port 12V 4-way splitter. The night before I'd run everything without the dew heater for a good 4hrs or so with no problems.
So now I know nothing about batteries but I didn't think dew heaters drew that much power.
Any idea on what's going on here? Do I just need to buy a bigger battery? Is the issue one of not so much the capacity, but the number of things trying to draw power simultaneously, in which case I should be buying more batteries instead of bigger batteries...?
