This from Cannon's post on the previous page;
Another area that a racer should check is that when using a discharger that they get a good contact on ALL cells before starting a discharge. I haves een a acase where contact was not obtained on a single cell. This effectively meant that 5 cells were flat but one cell was still heavily charged. The result when next charged was one cell that overcharged ... and landed 30 metres away.
So lesson is ... when using a discharger make sure you have a good contact on all cells. Some dischargers like the Wave discharger have inbuilt voltmeters. I always put the discharger on to voltmeter reading before discharging to see that I have a good contact with all cells.
Sounds like you had either a dodgey cell or the discharge tray did not have a good contact and therefore not fully discharged. A recipe for disaster.
My best advice is to discharge using your ICE and then put the battery on the smart tray. Than you can be reasonably confident.
