not necessarily. I charge at only 3.3A, you charge at 5A. Problem with mine is my power supply is only rated for 10A 12V = 140 watts. Charging 21.6v at 5A = 108watts at say 70% efficiency = 154watts. Thats a bit too much for the power supply IMO, so I only charge at 3.3A - and the power supply still gets pretty warm.

Anyway, charging at a higher current means the batteries will get hotter and take longer to cool down. SO the time saved in charging is lost in waiting for the batts to cool...
