I too cant beleive how i ever survived without the smart tray. Its incredible. My packs are now registering over 3300. I also stripped a stick pack SMC, put bars on it, equalized it, and it went from 2800 at best to 3400. all it took was one cell to drop off, and it false peaks. I was always a sceptic of equalizing etc, i always kept my RC easy, no lathe, stick packs etc. But now ive seen the light. Ive also realised it will be alot longer until i have to buy new packs! As a laugh, i dusted off an old 1700 sanyo pack. I was getting about 1500 off it, which i thought was still good for such an old pack. Well last night i equalised it, and did a std charge on it... 5 amps, and it came up to 1832! I simply dont get it. also the packs are ALOT cooler when they come off the charge.
One question i did have... if a pack vents... is this bad? does it mean its dead? i had a tamiya stick gold 3300, and i stripped it and put bars on it, and after charging (3422!) it started venting from two cells, from the positive end. made a weird sound and sat there. for a while. i havent tried the pack yet, just wondering what everyone knows about venting?
Oh and as for checking the way you put the pack in, i always look for the solder tabs or the corraly type connectors to be at the bottom. ive done the assembly in such a way, that id have to be drunk to put the pack in the wrong way... but regardless i always double check before hitting the button
