Had an odd experience with my cells today.
I've been racing them so far in stock indoors and use them just once a night and as soon as they come off the track I discharge them at 20amps to 5.4v (although recently 6v since my charger reset itself and I'm too lazy to change the setting
) I always get about 1900 out of the cells after a five minute race.
Today was my first outdoor race of the season, Scottish outdoors series first round, I'm running 19spec. I discharged them after the race and let them cool for atleast 1.5hours before recharging for later runs. The first pack I charged for a second time only took about 3200 which I though was odd but would easily last me a race so I just ran them. Then the second set I recharged which was for my final only took around 2400. The cells were warm like a normal peak and I had enough time to repeak them so I did, and it peaked like usual, just taking an extra 250ish. I didn't actualy get to run the final thanks to a cvd pin coming out
(after qualifying 5th in the A) So I discharged the whole pack and got about 3450 out of them, like I should.
So it appears that the cells are dropping below 6v very quickly when I put them on discharge after a race
(unfortunatly I didn't note the capacity taken out after each race, but I think it was only a couple hundred in each case) This has never happened when running stock indoors.
I equalise before the first charge, down to 0.6v then charge at 6 amps, 40mv delta on my Pro-Trak charger and always gives an input of 4200-4300.
Any ideas what may be causing it to drop voltage so quick on the discharge?
