Default Building an equalizing tray

Hi,

any guides on building an equalizing tray? Like what type of resisors I should use, how to make the cut off... schematics would be useful...

also.. how do you build one for a stick packs? like the thread posted previous that shows the discharge tray for stick packs on the acrylic board?

edit: this one..

buddy, spend $100 on a teamwave! its the best investment i ever done.

why waste $70 spending your money on components just to build a dinosaur that everyone is going to laugh at you and snicker behind your back

This guy wants to build something for himself and save some money, why are trying to discourage him? It costs far less than $70 to build one anyways.

D_o_S, send me a PM, I'll give you list of stuff and instructions to make a discharger/equalizer.

Fair enough, here's a simple one that works well with IB cells:
6x 1N5404 3A diodes
6x .47ohm resistors (at least 3W)

each pair of resistor/diode is connected to each cell. The positive band of the diode goes towards the negative terminal of the battery. This will discharge each cell to 0.6v and keep them there.

will this work for the stick pack configuration above? (the photo). or will it be different. im also curious to see if you can make one for stick packs that has a deans plug connector? thanks for the post. much appreciated.

Yes this can easly work for the stick pack config but if your going to have it so it can equalize as many packs as that one you would have to multiply how many packs you want it to be for. No you can't make one for deans connectors because then you could only discharge the battery and not equalize the batteries.

OK so all I need is 3 packs of these http://www.radioshack.com/product/in...tId=2062579&cp and 6 of these http://www.radioshack.com/product/in...tId=2062289&cp ?

If you look closely on the one open discharger, you can see the diode connected inline with the resistor I believe the way it discharges each cell is by going through the wrapping of the cell on the negative end each cell.

Yup, those are the parts. Although Radioshack isn't the cheapest place to get them.

Use 12 diodes connected in 6 pairs. Each diode in the pair connected in opposite directions so it doesn't matter how you connect the cells. You can also use bulbs in place of resistors for load.
