Dear Gurus,

I bought a pair of AAA nimh batteries rated at 1.2V 900mAh. Fast charge can be done in 5 hours @ 270mAh. Standard charge can be done in 15hours @ 90mA.

My doubt is assuming both batteries have different impedence, can they be charged in Series at say between 1.4v to 1.6v using a 5v dc source rated at 500mA ?

I intend to limit the current to 270mA and use a resistor to reduce the input voltage to 1.6V.

I am not sure would there be safety issues as i am not using any battery controller but just a direct connection to power. I intend to cutoff the power after 5 hour max

sincerely
