The C9000 has lots of space between cells, but the charger produces a lot of heat. The Maha C801D keeps cells much cooler even though it has very little space between cells.I would go with one that has a good amount of space between each of the cells. The maha C9000 is one to look at, the cells are spaced quite far apart which is unlike alot of chargers out there.
I can't comment however on how warm the unit itself gets though as I don't own one... yet
Hello Gadgeteer,
Welcome to CPF.
The Schulze chargers are very "cool..."
