When you charge ECU batteries, set the charger to no more than 3.6v cutoff per cell. that will get them 95% full but not over charged.
One thing I would not do is charge them while plugged into any ecu.
Goose,
Excellent suggestion about the cutoff voltage per/cell. Good way to avoid the "fresh charge" spike.
Just wondering why you recommend not charging while plugged into the ECU?
Thanks,
Craig
