Need help with hybrid battery module charging/discharging after P0A80 fault

I'm not getting any input on my thread :
2013 Yaris hybrid 1.5l 178k km P0A80 fault | PriusChat
so I'll start this more specific thread about charging/discharging hybrid modules.

The battery is out of the car still in one piece but all modules disconnected (Dr. Prius
graphs from before removing battery are in other thread).
Open circuit voltage on all 20 modules is 7.7V and after a week all are around 7.7V within .02V.

I just received the CQ3 charger and want to proceed but am unsure of the
next step especially as the internal resistance of all modules is between 21mOhm-22mOhm (doesn't sound bad), voltages according to Dr. Prius not looking that bad and there being quite a bit of
oxidation on terminals, I don't want to overly stress the modules.

Should I do a few second load test (with light bulb) first to identify if a module is bad or will
charge/dischargecycle results identify them anyway ?
