Dewalt batteries - bait and switch!
Wartex:
Dewalt quietly goes from high-end A123 cells to shitty Samsung cells.
Kiriakos-GR:
The Samsung cells are not shitty.
They are much better than many no-name one.
They do cost less of what you would pay to get cells from Japanese brands, and they have some quality.
Psi:
Did he make a mistake about the charge rate? I only listened to the video once and didn't go back to check but it sounded like he said the batteries were;
spec'ed at max 550mA charge rate but the charger was putting in 1.1A and so they were being charged over spec.
If there is two banks in parallel as he said at the start then 1.1A is fine, as its 550mA per cell.
Precisiontools:
Good vid...thanks for the heads up Wartex. I noticed towards the end he said he might go to Milwaukee but I have a friend who sells them here in Australia and they are having trouble with their batteries at the moment as well.

No I didn't. The manufacturer spec is 0.5C, which is 550 mA. The charger charges the cells in 1 hour. To charge 1.1 Ah cell in 1 hour, you have to pump 1.1+ A into it. Number of cells and configuration of the pack is irrelevant.
