Hhhhmmm, that's interesting, Chris must have changed as I know he defo used to use 10mv. Doesn't the manual say 20mv for nimh on sheet supplied, maybe he was quoting the party line
Judge it on temperature though I say, all cells when they are charged start to get warm. With nimh as soon as they are warm they are charged, not like the old nicads which you had to charge past the peak voltage and get them warm.
As an aside, I consider some sort of equaliser more important now than ever before. Some of the nimh cells I've had have wandered all over the place whilst left both partially charged and discharged. On assembling my latest cells I equalised them before their first charge and they were all over the place, I guess due to when that cell was actually matched. Similairly I have discharged a pack to 5.4v, left them for over 2 months and had 2 cells read 0.05V purely through self discharge. I equalised the pack and seems to have been fine, but I wouldn't want to make a habbit of it. So now I deliberatly leave my cells with charge in them and equalise them before charging on race day!
