Depends on the system, if you want to go ultra fancy you can monitor them to the individual cell or just monitor racks of cells and troubleshoot from there.What's the life of those 18650 batteries? Do you just replace them all on a schedule or have a way of locating the ones that need to go?
With the charge controller they actually have a very long life (depending on brand, etc). They're pretty ubiquitous in everything from electric razors, laptops, etc but without a proper charge controller they die quickly in those products.
