I have an RV setup of 2, 12V battery banks. The first consist of 2, 12V car batteries in parallel supplying a 1000w inverter. The second is 2 deep cycle marine 12V batteries in parallel supplying a 2000w inverter. I use two 100w solar panels to keep both banks charged. I recently purchased a Schumacher SE-1250 charger to start providing equalizer charges to the batteries. I have generated a tracker for measuring each cell temp and SG during the normal charging phase (10A) and for the EQ phase (30A). Each bank took about 12 hours to complete, 6 hours per battery. 5 hours at 10A and 1hour at 30A with readings every 30 mins for each cell. My plan is to do this quarterly to generate sufficient data to determine if I need to increase or decrease the EQ phase.
Cetaceans have lungs, meaning they breathe air. An individual can last without a breath from a few minutes to over two hours depending on the species. Cetacea are deliberate breathers who must be awake to inhale and exhale. When stale air, warmed from the lungs, is exhaled, it condenses as it meets colder external air. As with a terrestrial mammal breathing out on a cold day, a small cloud of 'steam' appears. This is called the 'spout' and varies across species in shape, angle and height. Species can be identified at a distance using this characteristic.
