I really like these battery's even just running the 2s without running in series, there is still no lag at all
they also hold there charge very well not notice any drain at all really

I am running simonk 40a esc's 3 of them and 3 sunnysky 2212 2450kv motors
so you would think a little lag in 2s but there is non
so I am lead to believe these really are 65-130c drain which is awesome!!!!

I've done a little testing on these batteries lately.


Early results suggest that the entire voltage curve for these batteries is moved up by about 4pcnt. Not only do these batteries comfortably charge to 4.35 volt, but they are well past their useful voltage at 3.6 volts. They also seem most happy stored at something closer to 4.0 volts.


I've been using a 2,400mAh 2S battery for simple testing. Charged to 4.2 v/cell, the pack cycles at about 2,050mAh. Charged to 4.35 v/Cell the pack cycles at something closer to 2,250mAh. In either case the cell do no cycle at the rated 2,400mAh.


I did my testing down to 3.3 v/Cell. I would not recommend this. There is NO capacity left in these cells below about 3.5 volts and the cells start warming up below about 3.6-3.7 v/.Cell.


The cells are extremely well matched. Internal resistance is 1.8 and 1.9 ohms and the cells cycle up and down in perfect unison.


I've been using a iCharge 4010 Duo for testing. The charger will let you specify a 4.35 voltage charge but it will not let you set a 4.0 volt storage charge. A minor inconvenience. You simply do a normal charge to 4.0 volts.


Flying this pack in my Yard Stick results in noticeably better performance. Granted this use only draws between 2 and 12 amps in flight but to my surprise the extra voltage IS noticeable. Some of this might be attributable to the low internal resista
