Default Dischargers

I'm talking about the tray-type dischargers/conditioner - thingees on the market.

What are these things?
What do they Do?
How do they do it?
Why should I want one?
Which one should I get?

I know that a lot for a Friday, but somebody (like Trickle) please indulge me. If I can find a suitable unit this weekend I'd like to buy one. If I need one.

Sidenote: Did anyone involved with this RC car thing go through anywhere near the same amount of brain damage I've had trying to figure out what I need and where to find it? It's been fun, but geeeeez!

A tray style discharger like a trinity Real Time is exactly what it looks like. It discharges each cell individually on its own little lightbulb. Currently, Novak is making one that will include a cutoff for each cell, but for now just unscrew each cell when the light is almost out. It discharges by using a resistor attached to a light bulb then attached to a screw. Just set your pack into the tray and screw all the screws into the batteries and the lights will come on. I'd wait for the NOVAK discharger, it looks pretty sick and has a cutoff built in so you don't have to watch the lights. Check your LHS first, then look around at tower hobbies. Integy also makes a good one.

Yep, an equalizer discharge each cell individually. It's a kind of synchronizing, so the pack as a whole perform better. It also help keeping the internal resistance lower, meaning more punch and acceleration.

Basically, there's two types: The ones that goes all the way down to zero volt and the ones with a auto-cutoff.

The ones with auto cut off, is usually pretty slow, while the ones with no cut off, are faster (10-20 amps).

So it's a matter of believe, if you want to go to zero or not. Most people find it's stressing the cells, if they come down to zero volts.

Check out the Rayspeed - it has selectable cut-off and selectable discharge rate 1 or 5 amps.

Personally, I'm discharging the whole pack at 20 amps, afterwards, I'm using a equalizer with cut-off. Works well.
