nimh cells making fizzing noises when discharging

[ben broughton]

I am returning to r/c racing after a few years break so anyone who can advise me I would be greatful. Thanks.

i have recently bought a few packs of new lrp vtec 3800mah cells. I have stored them without use for the last three weeks with about 15mins charge.

when i now go to discharge them at 10amps on my nosram stealth the cells bubble and fizz as if they are going to explode - so i quickly disconnected everything.

one set did not have this problem so i then transferred them to my lrp conditioning tray - again the fizzing noise but also with SMOKE coming from where the cells connect to the tray. The tray got red hot in about 5 secs at which point I disconnected everything again.

Does any one know whats going on here because i have a feeling something is about to explode in my face????

help!

Thanks
Ben.
