so i finally switched over to some radioshack 2000mah nimh cells for my mx-3s (damn thing goes through batteries like a lawnmower through grass) but im having some trouble getting them to charge right.
first let me say i DO NOT use the charge jack on the transmitter to charge them! ever! i have a little rig i made for my charger that i hook the whole battery tray right up to. using my integy 16x3v6 i discharge them at 2A and charge them at 1A, but the best voltage i can get out of them is about 10.8 volts, which stabilizes at around 10.5 after a few minutes in the radio. once the voltage settles, i can run for a couple days before a recharge, but the lower voltage affects the radios performance. another guy at the track uses the same cells (actually the 1800mah radioshack nimh) and gets about 11.6 on a fresh charge. what am i doing wrong?
i have been using AA's rechargables for about two years now.
11.4 volts is good. most of the time i am at least 11 volts on a full charge. all it takes is one battery not charging all the way and it will affect the others. maybe try another brand. i charge my batteries each time i go to the track. i would charge your batteries more often if you are using the radio more than a few times a week. also try not discharging them and just charge when they are low.
thats partially the problem. once my radio gets around 10 volts and below, the radio tends to glitch alot. a strong signal from the radio and i have no problems, but once the voltage gets low i start having problems with the already problematic flourescent lights at the track. the batt alarm doesnt go off until 9.1 volts, but i cant really run indoors below 10. i use my radio about 5 days out of the week.
I have a 300mah charger from Radio Shack to charge my Tx batterie pack. I have an M8 and I use the AA batteries. I have the 2300mah from Duracell. I leave it on the charger until it gets warm. I get close to 12v from the fresh pack and it'll settle down to about 11.5v.
