I have been conducting a lot of battery testing this winter and needed my test station in my downstairs office. It makes it very convenient to have the batteries in a good constant temperature..
This system can be used to conduct 20 hour capacity tests on batteries, cycle testing of batteries, track solar performance and can track multiple channels for current, energy used/supplied, voltage, watt hours, battery efficiency etc. etc. etc. etc...
Today I was just curious to find out exactly much energy it takes to charge an iPad Air 3G from a 12V bank via a small MSW inverter..
