Whats real about discharging at 0.2A, thats a all nigh test there, i dont have any lights that draw less then 1 amp, if you bothered to read post number 67 on this thread you will see i have already done the 0.5A test ! I can see 1 amp being useful, but any battery that gives the most mAh over 3 amp discharge will normaly give the most mAh and last longer for lower discharge test and you can work it out with simple math. Now if you wanted other test done why not ask........
I personaly dont find 2100's test of the panny useful as he is using a imax b6 charger with the maxium discharge of 1 amp with no data logging to back up his results, he has said in other post that the charger is out 0.2 volt to me when i question him and i know personaly the imax b6 and clones are not very good in nimh mode and the main charge leads are normaly out from 0.04 to 0.4 volts including the balance ports and 2100 has to use nimh mode to discharge lower then 3 volt. Im not have a dig at 2100 as hes a great bloke and great poster on this form im just stating it as i see it i dont mean no harm.
I have to admit, i "only" have a IMAX B6 so i am limited to 1A. Mainly that is for recharging my Pb because the stock ones take too long....i wasn't too keen on iChargers as they are over 70 bucks and i don't do RC. It's bad for regular Pb (non fancy AGM or what fancy types) of course to do above 0.3C but heck they are so cheap (15 bucks for a 7.2AH and yes it's a fresh one with ~ that capacity). From what i see on hobby sites, most entry level models have NiMH and Pb modes...so below 3V discharge is not an issue. Most flashlights do go below 3V per cell esp for 2 x 18650 lights and they don't dim much, if you don't believe my few tens of flashlights, check out HKJ, he probably has EVERYTHING in the market. LOL!
PS. I know there are some which do specifically Li only...but RC do make use if NiMH as well. If you ask Lambda, NiMH is not inferior to Li-ion.
iChargers are good for lead acid batteries (PB) but only from 2 to 24 volt upto 10 amps or 250 watt for my icharger 106B+ if you run the iCharger from a PB battery you can do regeneration charges witch are very handy.
There were a couple of good guys, i think DasFriek, who tests and includes graphs as they can log....wonder where are they. Some good guys like Agenthex has left too!
Where do you think my data charts come from ? i log using my icharger 106b+ connected to my computer for my battery tests i use logVeiw V2.7.4* with icharger 106B+ with the v3.14 firmware upgrade and then recalibrated the charger.
I use this program for my data log,s and for the data charts i post

I use the data tables instead of graphs becuse i find it simple and think it would be easy for other people to read and the data tables includes charge time updated every 2 seconds, voltage, watts, engery, mAh, plus induvidual cell voltage for upto 6 cells, internal temp of my charger, battery temperture, the chargers imput voltage from the power supply and so on and i can not get all that infomation on one graph.
I usualy only include the end of the charge cycle then hit the print screan button on the key board while the logVeiw program is running and opean on the screan of my computer, save the image in paint, then crop the image down with microsoft picture it! then up load the image to photobucket then post the image on the thread.
I cut out things like battery and charger tempture and induvidual cell voltage if im only doing one cell at a time to test.
