just got a new charger, superbrain 959, and i was wondering what to set it at for charging my batts. as of now i have a couple of 1900's. I think i have a problem tho, i can change the volts but i cant change the amps. if you know what i can do to change them please let me know. i had a timed charger and it seemed to work better on my batts. they seemed to have a longer run time on them. do u think that the brain is bad? please let me know what you guys think.
