6s drop off

[BrianG]

3.5v/cell is kinda high for an LVC value IMO. The voltage does dip on hard acceleration, and the closer you run to it's max discharge value, the more it will dip. So, when the pack is sitting at it's 3.7v nominal value, 0.2v isn't giving much leeway for voltage drop. I would go to 3.2v, or 3.3v/cell. Still allows plenty of safety zone, yet provides ample compensation for v-drop and more runtime.

I'm headed back to the track on Weds, when the power drops down I will try switching the power off and then back on, this should tell me if it's the 50% lvc kicking in.

Go with 3.1v per cell. You must be hitting the lvc. I have run those cells with good success myself. I have a feeling that you are pushing them pretty hard in a truggy. I run 5s packs of them in my hyper buggy. Go with a 5s pack of larger mah cells and a 2000kv motor, or the cc 2200 motor, great 5s motor, especially geared for 40.

You are geared pretty high, and have lower motor rpms.
