Its simple you just use an extra battery bar to connect the cell to the pack. You will probably have to by a new package of battery bars to do this. Then solder the connection you need for your ESC..Just make sure that the the battery bars are still alternating sides like you would on a 6 cell pack.
If you use wires to connect the last cell, you willl raise the internal resistance of the battery pack. Something you don't want.

This is either the dumbest question I've seen on the board, or we just haven't understood your problem clearly. I would have thought it was fairly obvious how you solder another cell on.

I think this guys wants to make a 7 cell out of a stick pack (7 cell hump pack)

If thats the case, you have to completly dissasemble the pack, as in remove all shrink wrap and rip off the 'welded' tabs connecting the cells together in stick formation. Then get some battery bars. solder the bars to the ends of the cells, from one cells (+) to the next cells (-). If you need to ask any other questions about how to do this, you probably shouldn't even mess around with it!!!!

Start by lining up two cells, with the negative and positve sides of the batts opposite themselves. Solder a batt bar to the positive of one and the negative of the other. Leave either the positive or negative open of the first batt. Keep doing the batts like that..positive to negative until you get to the last one. Then the opposite of what you left open on the starting end will be open. If you left the neg open, then the last one should have a positive open.

If you plan to solder direct every time, solder a batt bar on pointing up, then bend it around the top of the pack, so it is flat. That's where you solder your speedo wires.

If you are going to use plugs, then solder a wire to each end that's open, then solder the ends of the wire to the plug. Make sure the polarity of the plug matches the polarity of the speed control plug.

You connect it just like all the other cells! Instead of putting an endbar on the 6th cell when assembling the pack put another horizontal (regular position) bar on the end connecting it to the 7th cell. Once the 7th cell is connected to the 6th cell solder an endbar on to the remaining end. You are either looking for something different then we think, or you are making this way too complicated.

I was goingto defend the question..saying that most jigs only allow for up to 6 cells....but that last comment blew my defence outof the water...

Ok...to connect the seventh cell...you do it exactly like the previous 6cells

[]_[]T[]_[]T[]_[]T[]

sorry it's so primitive....but [] is a cell and looking at it you would have a battery bar at the bottom _ and then on the to...T.....to connect them all together....macking sure to go from the + on one cell to the - on the next....

There is no symbol for an elevated underscore...or overscore if you will....the closest I could find was the T....
Ignore the vertical line on the T.....


Possibly you should consider a name change?(J/K)
