I assume you want to know why the LVC was set at 3.4v/cell, yet the cells were 3.7v when measured? Two reasons: 1) cell voltages will drift back up a bit when left unloaded for a few minutes, and 2) depending on how the LVC actually works, if it read a momentary 3.4v/cell voltage sag because of high acceleration urrent, it would trip the LVC even though the nominal voltage is closer to 3.7v/cell.

Nice job by the way!

Wow, the Castle motors never cease to amaze me.

And very nice build. I love the motor protection. What kind of net/setup do you have there? I'm looking for some ideas on how to protect a motor I have

That's what I see with the HV ICE 160. The power will cut off under hard acceleration near the end of the pack (voltage momentarily drops below lvc setting), but will continue to supply power if I drive less aggressively. A good feature - meaning I can drive it back to my car at the end of a run, rather than carry it. Probably also good for airplanes to allow them to land - which it was designed for.

Thanks BrianG, I had a feeling that was the deal with the cell voltages.
DJ_Sparky, I used an Outerwears Large Electric motor protector which I cut in two peices to fit on the front and the rear of the Neu. Was a real PIA to fit over but it fit allowing the fan to cool the motor.

what are those rubber band rings that are holding the outerwears on the motor?

Man, I love the look and size of the Baja 5t's, but I'm wondering if these vehicles are a bit more than I want to chew. I'm so comfortable with my 1/8 sized 6s MT's that I wonder if I shouldn't just enjoy those for a while, and maybe creep up in power when the new CC ICE MMM XL HV ???? comes out, and check out 8-10s?

Hopefully one day someone will come out with an awesome 4x4 baja 5t, or a cool conversion? Then again, my buddies and I are brainstorming a custom Losi XXL 1/5 scale chassis. We've already finished our custom 1/8 chassis and skids, and will soon be done with an Erevo tranny version with side battery trays!

yea me to. I think most of us hope to have an HPI Baja one of these days, but dumping a grand just to get started is allot to ask of anyone. Especially in todays economy. Looking at hopups and brushless conversions owning an electric 5b or 5t will cost us about $5K so we have to creep up on something like that. Good luck with dealing with your urges. We all know this is like crack for us, and we have no plans on breaking the habit. Plus there is no medication that will help ween us from this habit. Oh well.


SUPERMAXX YOUR LIFE.

They are just rubber plumbing rings. On the rear of the motor I have installed a hydraulic pipe clamp that is fixed to the rear chassis for extra support.
