My e-revo brushless edition build

I'd like Jason from MA see that chart of yours, Rock on HC !!

He should know a lot about these charts, I read a post from him saying that they use the CBA analyzer to test their cells. They would really need to use the amplifiers offered by the same company to test at really high wattage.
The next lipos I'll be analyzing will be a pair of NEU 3900 4S 25C constant and a pair of Zippy H 3500 4S 20C constant.

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.
