Just wondering if i should use abit of common sense & not put them in the sun.
& the batts were getting to hot for my liking after charge.
Been using these batts for the last month racing & they did`nt feel or look happy at all.

Jolly: Yeah I have done the same thing....except it was 90+ degrees....made them feel really crappy... Keep'um in the shade.

Hi Yodace,
I usually take my packs down on a Turbo 35 to 5.4 volts, then I leave them on the Smart Tray for about 20 minutes. I don't usually let them stay on until the lights go out.

Do think leaving the batteries on until the light goes out will hurt the cells?

You can leave them on until the lights go out, it just gives you a "deeper" discharge. In fact leaving them on overnight every now and then is a good idea. Testing has shown that when you leave them on the tray overnight you get the benefits of deadshorting (increased voltage) without the danger of damaging the cells.

I left my batteries on the tray overnight on Friday then the rain came on Saturday? SHould I leave them or recharge the packs?

I want to be sure I am understanding this correctly - it is OK to leave the batteries on an EQUALIZING tray that will only take them to .9v/cell, not on a DISCHARGING tray (without cutoff) that would take them to 0v/cell - right?
Isn't it bad, very bad for a NiMH cell to be completely discharged to 0v/cell? I thought that was why it is important to be sure a discharger has a cutoff that stops the discharge.
Isn't that the difference in a discharger and equalizer - that a discharger just simulates running the car in race conditions, while an equalizing tray completes the discharge of each cell down to an appropriate voltage?

RCtoyguy,
In my opinion you're correct. Leaving them on the Promatch Smartray overnight won't hurt anything. Other trays I can't speak for, I think the best compromise of performance and longevity comes from equalizing the pack down to .9 volts per cell.
Yodace,
I would probably take them off the tray if it's going to be a few days before you use them again.
