I charge my 1500 or 1600maH AA 8 cell Nimhs on my G325 all the time at 3A - even 3.5A. The trickle seems to be ok too, altho unnecessary. It's nice also to not have to worry abt memory effects. Just stick them on the charger anytime. Of course, what ur talking abt is charging on the 4 cell portion of the charger. I have not tried that, but my understanding is that it starts at 500ma, then tapers down to 250 ma as the cells get charged. There is a slight V difference between Nicds and Minhs, but I don't think it wud have much effect. So it'll take several hours from empty to full charge. However,the 600mah Nicd packs seem to charge in 1/2 hr or less, so this indicates to me its charging at a lot higher rate than 500ma. The green blinking led tends to blink faster and for a shorter time when its charged - it shud do the same for the Nimhs, but by how much - u'll just have to try it. Just check periodically to see if they're getting warm. Gud idea, Dave. Think I'll make some up myself... -- Tom Rust Nanochip Inc Box 13249 Oakland, CA 94661 (510) 339-6263 (510) 339-9636 FAX http://www.nanochip.com RCSE-List facilities provided by Model Airplane News.
