View Full Version : Battery cycle parameters BRhodes 03-13-2007, 06:31 PM I would like to use my GFX to cycle my batteries to make sure they are still ok. What parameters should I use (charge at 6.0 and discharge at 35 down to .9?)and what numbers should I expect for a 4 cell pack? Any thoughts or experiences in this would be appreciated. Thanks. Bob DK47 03-13-2007, 07:08 PM 2 peak charge 6.0 amp 1st peak .02 peak detect 120 sec delay 6.0 amp 2nd peak .02 peak detect 15 sec delay 35 amp discharge to 3.60 [even though they tell us not to} this is pretty close to most matchers spec to compare label #'s BRhodes 03-13-2007, 08:30 PM So then the average pack voltage should be close to the sum of the average voltage listed on each cell?

BRhodes 03-14-2007, 09:53 AM What cells are being discussed, 3800, 4200, 4200wc or does it matter? 4200WC's are what I was referring to. pmsimkins 03-14-2007, 02:42 PM When you look at the numbers pay the most attention to the voltage at 300 seconds and IR. My assumption is you aren't racing mod. If you are then runtime as well. dave w 1 03-14-2007, 03:47 PM 0.1 ON SEC REPEAK dont do .02 batts ket way hot!! BRhodes 03-14-2007, 06:23 PM 0.1 ON SEC REPEAK dont do .02 batts ket way hot!! I am doing .02 on first peak at 6.0 amps and it seems like they get hotter than what I would expect. I cannot tell you exactly what temp but they seem very warm. I am new to the NIMH worl but they seem quite a bit warmer than my Nicads back in the day.
