my orion 1600 took around 45 minutes for the first charge, so a little less like a half hour or so for the rx pack. I have no idea how long it would take the tx cells to charge.

I charged my rx packs, 2 of them 1200 mh 6.0v the first I did on my Indi at .5mah, and it took about 45 minutes and put in 1269, and I turned it off before it was finished. I then charged my Tx pack, 8 cell at 2400 Venims, it took 35 minutes and put in 2467 and was complete. Both were charged at 0.5 mah with a o.2 detect rating. I also charged another 1200 rx pack on my super brain 959 at 0.5 and it took about 35 minutes, but not to sure on how many miliamps it took.

If the batteries are completely drained, it will take approx 700mah/50ma=14 hours to fully charge them at 50 ma rate of charge. Adjust of course for the other rate of charge.

I charge mine using a digital peak charger set at a fairly low charge rate, 250ma and let the charger make the decision when the job is done.

I'm finding that after some practice time and 4 races the digital peak charger puts around 250 mah back into the cells before they peak. So that would be 5 hours of charging at 50ma rate on your charger.

If you are putting in 1269 mah in 45 minutes you are charging those batteries at around 1.7 amps. If you are putting in 2467 in 35 minutes you are charging those cells at 4.2 amps. Wouldn't you be better off charging them at a slower rate? You are definitely charging them at a much higher rate than the guy that asked the question and has a 50ma / 120ma slow charger.

Yeah, the tx I did was at 2 am, and it got done around 4 or 5, so I guess that was 3 hours, my bad. the rx might have been an hour and a half before I pulled it off, I am not to sure, the charger might have said 96 instead of 46 for the minutes charged, It was at 2 am, and I didn't have my glasses on. Sorry for the not quite accurate info.

yes, good digital charger, I think the Triton's are on sale at tower hobby for 89.99, the ICE are also good chargers, they are about 120-140. THe ICe charges at a higher rate, so if you are running electric vehicles you can charge the batteries at 6, where as the Tritons can charge at up to 5. The tritons are nice because you do not have to specify battery types, whereas with the ICE you do. The Integy Indi series are also good chargers, or the Novak or Reedy.
