As I am looking for a solid reliable charger would you consider this to be a good choice and worth the extra money?

Hi I have just returned my RC/Power 601bc charger after having a number of issues with it and am now concidering the Bantam e-Station BC6. Does anyone use this charger and if so how would you rate it?  I thought I would get some feedback on this unit before I rushed out to buy one (this time!). Any info would be gratefully received.

I've just bought one of these chargers from Vapextech for £69.99 (which included the 240v power supply!!).  The only thing that is perplexing me is the temperature sensor.  The manual bangs on about the temperature sensing abilities and their benefits but there is no probe included with the unit, nor does there seem to be any way of attaching one. Any ideas?

OK, I have a reply from Vapextech.  The guy has told me to charge my 3700mAh NiMH pack at 1600ma and let it run until it switches off.  If it goes wrong I should contact them to replace the cells. Not quite the technical repsone I was after but I'll give it a go.  I have found an interesting site however regarding the charging of various cells and they suggest that NiMH do not respond well to Peak Voltage Detection as they do not display this caracteristic very well.  They suggest using dT/dt termination which monitors the temperature rise over time and ends the charging process when a preset threshold is met. The unfortunate this is that I don't think the 601bc can do this I have included a link to this site for anyone who is curious: http://www.mpoweruk.com/chargers.htm Enjoy!

Thanks Timbo, I thought that was the case. One other question if I may.  When discharging cells, what is an ideal voltage to take them down to (per cell).  I have been taking them to 1v but some say it should be higher.

Thanks for all the info chaps.  I have checked out the link to the Panasonic site which is a very interesting read. My peak detect value at present is 10mv so I will try and drop this to 5mv just in case the charger is not sensing the drop off.  I see that the lower the charge rate the smaller this voltage drop is so perhaps this may be the cause of my issue. Would I be correct in saying that if I want to charge a 3000mAh pack then I would need to pump in 120-140% of this value to receive a full charge (i.e. 3600-4200mAh) I have also contacted the supplier of the charger (Vapextech) to see what their opinion is (no reply as of yet but I will let you know what they say).

Hi All, I have recently bought an RC-Power 601 bc and have had a few problems. Firstly, the charger didn't come with the temperature sensor so if anyone knows of a compatible one I would be very interested to hear. Secondly, I was under the impression that it used Delta Peak Voltage detection to terminate charging.  I am currently charging NiMH cells and the unit seems to just pump in the power until the cells are nicely roasted.  I am charging between C/5 and C/3 but is seems not to make any difference.  I have left the cells as long as I dare but have chickened out when they are v-hot to touch. Any ideas or advice would be greatly appreciated. P.S. The instructions seem to leave a lot to the imagination also.
