Male Speaker: This video is about how to use a Stick Pack Equalizer. Nickel-metal hydride cells such as these Royan 4500 and they are like to be equalized, so each cell is the same before you charge them backup.
Normally, when raising cause the cells are configured in a side-by-side format. So, that the ends of each cell are flat, so you can connect on to each cell. There are many different discharge trays to use side-by-side cells. But if you are using stick packs like this, the cells could be just as good, it can be good quality high power cell, it can cost just as much, but getting access to the ends of the cells shows the difficult because they are buried inside a sturdy pack.
These sorts of packs are used for racing type vehicles, but also they can be used for racing in cars such as tell me a minute and then in other classes of cars too. Much more released a stick pack equalizer, so you can see it here we got the cells, they nicely have diagramed on that. But we got the connections pins on the sides, but it is not majorly obvious how these connection pins that connect to the pack. So, the pack is heat sink all the way over and there is no opposite way that you can connection to the ends of the cells.
So, what they suggest to do is cut a small section of each shrink out corresponding with the location of the pin and what this does is a connection beside of the cell, which is also the bottom of the cells that's the negative side of the cell.
So, if actually what about this connection here does is the bottom of this cell, which is packed connection there between those two cells, so there is three of the outside and two of the outside and in combination with the power lead, you've got a connection available to the junction of every single pair of cells. So, I've already cut out the three, cut out from outside, two cut out from outside, so they correspond with the pins. So, you put it into the discharge tray like that tilt up you can see how they cut out correspond with the pins. You have to make sure that you get it in the tray in the corresponding way, so this red cable corresponds with this red cable so this is positive top of that cell and negative on that cell.
So, you put it in the tray and you start connecting it up. I'll start to do this from the bottom first, just connect all pins together and you see the lights had started coming on. What you needed to know is just connect up the power lead, which will complete the circuit and they go. All the lights were illuminated and we got a flashing one here to show its working. And what happens in practice is as this is discharging, these lights will start to go out to start dim and then they workout all together, and then this one over here will go out. When it's totally out, you can take it off that and put it immediately on charges and caught in bolt into charges straight away and not to leave it sorts there is flat pack. So, what this does is it discharges each cell individually, so they will discharge all the way down. If you discharge the pack as a whole, what will happen is some of the cells would discharge before the other ones, so you'll end up with the cells, which has got some charge left in it.
So, when you come to charge the pack, this one cell make it over charged they'll probably become hot during charging and it may or may not the whole pack doesn't reach it's full capacity because the charger will deduct that this one cell has over charged and proceed in that whole pack is charged. So, there we go a quick demonstration of how the much more stick pack equalizer tray works. I showed you how to put out the heat shrink on the sides corresponding the pins and how to fit it into the tray.
