As this has come up again I feel it only right to point out the latest charging advice at the top of the electrics section. I no longer apply or recomend the advice I gave above. I'm now equalive to 0.9V/cell, then charge at 4.2A (4200 cells) at 3mv/cell (the lowest setting on my charger, they have never false peaked yet on this).
Metla, any cells that are 'too hot to touch' are I suggest dangerous, in fact any temperature anywhere near. This is the problem with the cheaper chargers, the delta isn't adjustable and in an effort to charge everything (nimh and nicad), till they are full and low risk of false peaking, the delta is too high. Essentially the cells are often overcharged through no fault of the user.
Fortuantly you are using 3700's which are in my opinion the best cells ever, much more robust than latest China cells.
