Model Forum / Radio Controlled / Land Models / August 2005damaged_cell
One of the cells in my battery pack has cracked open and it gets hotter then the other cells when riding. Is this a well known scenario? And what is the best solution to this problem? Here is a picture of the damaged cell: http://www.mip.sdu.dk/~beier/damaged_cell.jpg > One of the cells in my battery pack has cracked open and it gets hotter > then the other cells when riding.

Doc Replace the pack..or..solder in/replace the battery with a new one and use the pack. The cell has shorted out. > One of the cells in my battery pack has cracked open and it gets hotter then > the other cells when riding. Is this a well known scenario?

If you have 1 dead cell and 5 charged ones you can't charge the dead cell without over-charging the charged ones. Discharge all the cells to the same level, then replace the cell. Since your taking the pack apart you might consider getting rid of the stick configuration for a more efficient race style pack. Buy some battery bars. If you have not soldered on batteries before you need a hot iron to do it. I had a 20w I used for electronics work that could not melt solder on a battery. I had to get a 40w for batteries. If soldering and messing with batteries is totally new to you then I hope you have a good hobby shop near you. See if they can fix the battery for you. |
