It's official, I am mad at NEU. Graphs from a pair of NEU 3900 mah 4S 25C constant and graphs from a pair of ZIPPY-H 3500 mah 4S 20C constant. Those lipos have the same age and the same amount of cycles on them. Used in the same truck on mostly a race track. Some of the cycles were for bashing and two cycles each of stop and go running when I was testing that aluminum slipper pad.
NEU 3900 4S #1 (in red)
Discharge rate: 5.90 A
Starting voltage: 16.74 V
Ending Voltage: 12.00 V
Total Time: 36 min. 5 sec.
Tested Capacity: 3545 mah
NEU 3900 4S #2 (in black)
Discharge rate: 5.90 A
Starting voltage: 16.70 V
Ending Voltage: 12.00 V
Total Time: 35 min. 19 sec.
Tested Capacity: 3470 mah
ZIPPY-H 3500 4S #1 (in black)
Discharge rate: 5.90 A
Starting voltage: 16.70 V
Ending Voltage: 12.00 V
Total Time: 35 min. 06 sec.
Tested Capacity: 3449 mah
ZIPPY-H 3500 4S #2 (in red)
Discharge rate: 5.90 A
Starting voltage: 16.70 V
Ending Voltage: 12.00 V
Total Time: 35 min. 17 sec.
Tested Capacity: 3467 mah
And all the graphs overlaid on the same chart.
Zippys hold a higher voltage under the same load and yield about the same run time even though they are 3500 mah. The more I play with this CBA, the more I like Hobby King. I'm anxious to get Hyperions and Thunder Powers to analyze those also. But I am not going to get NEU lipos anymore.
