Replacing my Converter/Charger - Help

BFL I have the earlier PM3 75LK and it only adjusts from 13-15.5v That's the only thing I noticed different in the manual too...the range on Steves said 13-16.5v. One warning Steve. Be vewy vewy careful using the on/off switch from single to three stage. It is fragile....don't know that I "stabbed away in the dark" : -), but I did break it. Fortunately it was set to single stage/adjustable and I've no use for the 3 stage capability. I'd highly suggest BFLs suggestion of opening up those tiny access holes for better access. It's easy to remove the cover to do that. (BFL my batts seem to have made a fair recovery. One cell's a bit low but the other 5 are 1.275S+-SG and are tolerating loads typically.....so far.
