I need help, I'm recently back into r/c and my how things have changed . I was hoping for help with setting up my peak charger with my stock NiMH battery. My charger adjusts up to 6 amp and I charged at 4 is that OK ? There is also a safety setting to kick off the charger up to 5000 mah I think. Should I set that at 3000 because that's what my battery's are rated at or will the peak charger shut it off without this setting. Any suggestions would be appreciated and could someone clue me in on discharging as well again THANK YOU !
