what type of 3000's??? SMH or UMH I used 5amp charge with .03 cut off and with HV's I charged 5-6 amps with .05 cut off. On HV's I went with the higher amp charge when I ran stock. I kept it at 5 amp for mod. Hope this helps you some.
REMEMBER THE GOOD OLE DAYS..........THEY'RE NEVER COMING BACK SO WE'RE STUCK WITH THE MESS IN FRONT OF US!!!!
