I feel a difference off the bat.
It took me awhile to get it working. Update and settings. Setting are the key, the numbers are different than our old chargers.
My settings for IB 3800 are 6 or 7 amps, 4.0mvs, 50c, 180 sec force charge.
The difference I feel is not at the beginning of the race but at the end. The batts are staying constant through the five min.
Has anyone charged a practice pack, and ran it till it died? Notice how it goes from medium fast to a crawl at the end of practice? Cause all the cells are done at the same time, imo. I could be way off.
