OK here is a running chart of the most popular testers running a test on the same battery.
All tester where set to the highest C/D/C setting.
Results are:
The Foxnovo set to 1000mA capacity test does a charge at 1A but a discharge at only .5A Temperature was quite steady and the discharge and charge lines where very clean. Results 2633mAh
TheOPUSset to 1000mA capacity test does a charge at ~1A and a discharge at ~1A(more like ~1.5A) I ran this test twice on 2 different chargers on different slots as the results vere very odd. But as you can see the curves are the same on both chargers in different slots so I guess that is the algorithm that that charger/tester uses.The temperatureas expected was slightly elevated (about 5C above ambient) during the discharge cycle.
Results 2723mAh
The LittoKala set to 1000mA does a discharge at 500mA and a charge at 1000mA The discharge trace looked to be a bit noisy but charge was relatively clean.
Not much as far as temperature variation. maybe 1C to 2C from ambient.
Results 2598 mAh
The Zanflair set to max which is only 500mA for charge and discharge. Very clean discharge trace but charging is very noisy.
Also temperature is negligible
Results 2830 mAh
The SKYRC is infinitely adjustable so I set it at 1A charge and 1A discharge. Very clean trace on both charge and discharge Temperature rise was expected at a 1A discharge and the cell did not disappoint ~3C above ambient.
Results 2561mAh
The iCharger x6 was set to 1A charge and 1A discharge kind of a noisy discharge and charge trace. I may do this one again.
Temperature as expected at a 1A discharge
Results 2277mAh
If I had the money SKYRC all the way.
IF I want to stress the cellsOPUSdoes a good job hence all the complaints about the heat.
I do like the Foxnovo as it is very clean but does not stress the cells at 1A so I count on IR of the cell to guide me in this scenario.
LittoKala and Zanflair are on the bottom of my list not worth the money even at half the price. IMHO.
There you go and all the graphs to back up the conclusion.
If Megacellcharger wants to sell me a unit at cost or better yet donate so that I can run an analysis on it and report back to the board how I feel about it please PM me.
