New battery for the Pulsar Dome

Weather has been terrible since last observation (dec 12th) but when I tried to open the dome last night, I realized the battery was dead with a broken cell. Reason may be the -7°C we had in december and a low charge...

Anyway, I went to buy a replacement today (I switched to a 12V/22Ah instrad of the 18Ah that was installed initially). I also added a BluSolar PWM Light Charge Controller. I'll see if the solar panel finally work and having it not directly on the battery is better - time will tell.
