I recently purchased a Ryobi weed eater and a Dewalt leaf bower. Both run on Lithium ion packs. The Dewalt pack (20v/ 5ah) gets pretty warm, warmer than I would like, when charging in the supplied DCB115 charger, Probably due to its fast charge capability. After doing some research, I have noticed that when a pack fails, it is always due to one or two bad cells in the pack. I am wondering if these chargers use cell balancing when charging. It is leading me to beleive that these chargers are just charging and not minitoring or balancing each cell so that they all get the same charge. Does anyone have any input on how these chargers operate and your experiences?
Thanks
