Had this happen a few times, recalibrated the ESC fixed one time, 2nd time I had a dry joint in one of the bullet connections although was still connected but major resistance. Other issue is on the cheaper motors that have the hard brittle phase wires you have to solder the bullets to! In time the vibration can cause headaches

Bench racing can be informative but the 2s and 3s 6,000 mAh versions of these packs performed very well during speedruns in my RC car (I have test videos to show it). For the price, the 6,000 mAh version was very good! I would love to see you include speedruns along with your bench testing for added information/data. The 3s 6,000 mAh hit 99 mph and my top of the line SMC 6,500 mAh 150c hit 102 mph. The 2s version hit 80 and my CNHL 8,000 120c hit 81.5 mph. When you factor in the price, these performed exceptionally well.
@RCexplained 9 күн бұрын
It's very likely that the LiPos are highly inconsistent from pack to pack and certainly possible for someone to get decent ones. The two I have show and demonstrate that they are quite awful. I've tried speedruns and learned that it's much harder to get consistency in a controlled manner. Keeping all parameters the same all year round is already challenging enough with the load tests and resistance tests. I've not seen a battery pull this low of current on the load test, I can't imagine how they would be in a speed run. I could do a speed run and calculate IR at load. There's no way for me to get top speeds consistently in the areas im able to run at.
@BriansRCStuff 9 күн бұрын
@@RCexplained I could see the consistency argument being possible. That being said, both the 2s and 3s I ran ran very well. I find with 2s speedruns, provided I used a long road and it is not windy, I can get results within a few 1/10ths of a mph with each run and in a video where I tested my 2 CNHL 2s LIPOs, I was within 0.1 mph on the 2 runs. According to my telemetry data, I pulled over 150+ continuous amps when at full throttle during my speedruns out of the 2s and 3s 6,000 mAh versions of the Turnigy Rapid 100C LIPOs and I was VERY happy with how the 2 I have performed, especially at their price point.
@RCexplained 9 күн бұрын
That's pretty good Brian. I'm sure the packs I have and it seems others do as well, would perform equally poor in my test setup as in the speed run vehicles. It's essentially the same test but pulling more current and hitting lower voltage earlier.

Wow I didn't expect them to test this bad. Mine show about 3~4 internal resistance per cell, yet they are the second best performing packs in my XRT second only to my Gens Ace Basher packs and not by that much. My Hoovo and Zeee packs from Amazon totally suck and hit LVC early because of the extreme voltage draw down they have.

Not that much voltage drop, when LVC kicks in they are done whereas my cheap Amazon batteries still have around 3.6 volts in them when they trip LVC. Traxxas LVC is at about 3.3 or 3.4. These batteries are at 3.45 usually when LVC kicks in. I look forward to when I can try a set of real expensive batteries. Being retired now I have to watch my spending.

A battery can not discharge a specific current if that current pushes the battery over 60C in temperature. I collected data by testing what batteries could actually do and used it to create an empirical formula around capacity and internal resistance. It's not perfect but I can assure you its much closer then a C rating on a label will be. There are a couple videos on the channel that talk to these points a bit further.
