hundreds of large Absolyte 2V cells in 24 volt battery banks. They would like some way to quantify the individual cell health. Inspection time available at each site is limited and the battery SOC will vary. These are off-grid sites and there is no outside power sources available to do actual discharge testing and then the required recharge. If it was absolutely essential, the customer could bring a generator to each site and use a backup battery charger to put some charge current into the string. But this would be less desirable. Battery strings can be temporarily taken offline, but cells will ideally still need to be connected in series.</div><div><br></div><div>What is the favorite magic box type meter for this application?
