A123, or LiFePO4 1S to 8S BATTERY ONLY. 
WITH BALANCE WIRING

Charge and discharge battery pack.
With 1S to 8S. 

NO CV timeout, and 16 hour charge time limit. 
CV termination is 500thC.  You may need to fine tune termination current to suit battery type. If it sits for 40 to 80 mins at CV after charging and balance is complete then thats perfect.  If its too short, as it may be, then reduce the TERMINATION CURRENT slightly. And retest on next charge. And do the opposite if CV continues beyond 80 mins after balance is good on screen.
