The Prolong system will do the whole pack.
Get the charger/discharger system to do a complete reconditioning job.

 

As a general rule a website search engine's box is never going to work as well as going directly to Google or similar service.

As for working on modules, once you spend another $20K on the latest system like professor Joe does over at https://2ndlifebattery.com/contact-us/ every half-dozen years you can process 80 modules at a time...

But for the rest of us, we use hobby chargers, which aren't designed for the job but work fairly well... Main thing that speeds things up for us is how powerful each individual charger is... I like SkyRC chargers and the difference in charging time between their 50w model and 60w model is significant.

Whereas the hobby chargers that allow you to process 4 different batteries at once will often promote a huge amount of wattage, but once you divide that wattage number by 4 you're usually looking at individual chargers that are much less wattage than what SkyRC charges with.

Also, for best results, when you're all done reconditioning modules you're gonna want to grid charge the whole pack / use a high voltage trickle charger to balance the modules via a Prolong or Maxx volt system...

I'm using the Maxx-Volts whole pack charger on my original 260k pack. It has kept the pack in perfect balance 0.06v voltage difference max.
