i have been working on a MAX712 battery charger, and i was a little unsure of some of my calculations. my problem lies with the value of Rsense, i plan to have a charge time of 4.4 hours, charging 8 series AA cells at 2.5A hours each. the 2 results i got are 0.4Ω and 2.27Ω of resistance. one is just the inverted of the other. are my calculations correct?
