    Nissan Leaf Cells Test Data

    Hey all, I modeled all 3 types of Leaf modules and posted them on my grab cad account. There is the first gen module(older tuna can type), and the 2 different type of gen 2 modules, with bracket and without. I did not take them apart to model the guts, but the exterior dims, bolt locations...

    Agni motor tuning and racing

    Hi guys, I was never able to dyno both brush holders. I will say this power *seemed about the same* however with the LMC holder which has more plastic or Bakelite, it does not melt as easy as the Agni holders do. This is not all good however, when I was running the Agni holder they reach...

    Hey Guys just found the Tork India video. http://torkmotorcycles.com/wp-content/uploads/2014/01/TORK-INDIA_-FZ-Electric-Feature_-PowerDrift.mp4 They build a Emoto with the 111rdr and look at these numbers they are getting this is a screenshot of the video. Not sure exactly what they are doing...

    Agni motor tuning and racing

    The brush holder is not something that Jozzer sells. I asked him about this holder he said that though it may push more current it may not actually OUTPUT more power. I had to buy this sight unseen with no data to support if it actually produces results. I will be taking both holders to the...

    Agni motor tuning and racing

    Here is a pic of the comutator. I was running at 100v and 425 amps for about 5-8 sec bursts doing doughnuts, got a little carried away. I have a much better brusholder to install that will handle the current better. Attached is a pic of the new brush holder with larger wedge shape brushes.

    Agni motor tuning and racing

    So I was running my 111r a bit hard and a little bit of smoke started coming out, I noticed immediately and shut it down. Pulled the brush holder and it looks ok just dirty commuter. How much damage have I done? Should I take the motor apart and clean up the commutator on the lathe? Or just...

    Battery knundrum?

    Wesnwell, Methods LVC board only draws microamps. Dogman, I have cycled and test these quite a bit, this should be the last bad egg that needs weeded out. Your solution is good, however I am running the batteries up to 20C max and so not having an extra safety ( LVC) kinda sketches me out...

    Battery knundrum?

    I have a sub-pack that is made up of five 6s Turnigy Nanotechs in parallel, with both the 10ga leads paralleled and the balance leads paralleled with Methods board. In other words it is a 6s5p pack. I was running it for the first time and then it sat overnight and I checked the cell voltages...

    New Agni Racing motor 111RDR

    Well I finally have my 111r up and running, not out to the track yet, just on the street in front of my house. I will tell you it is damn impressive! I have had it around 35kw peak, planning on running it up a it higher when I get the gizmo(arduino contoller) and water spraying setup. Is...

    Modular Hobby Cell Battery Pack Design

    Hey All back from vacation and got the kart running so that I could test some batteries! I ran a 12s1p pack 5ah at 50v. I ran 2 tests the first at current limited to 100 amps (20C) and did a few laps in the neighborhood, hottest temp battery temp was 28 Celsius with a low ambient and low...

    Modular Hobby Cell Battery Pack Design

    I do expect the cells to get fairly warm while racing, I am not sure how much. This project is an experiment for me, to build a smaller race car (read less cost), so that when I build a full size car I will have learned a ton and will not make expensive noob mistakes. So this pack while...

    Modular Hobby Cell Battery Pack Design

    AW and Dogman, I am well within the C-rates for the pack, they are 35-70C Nano-techs. However it is a racing kart and will get driven hard. I think the pack will last 15-20 minutes of racing or less. Lets call it 15 minute for a nice round .25hr figure. I have a 25Ahr pack so average...

    Dogman, Do you use anything special for chafing? (Of the batteries that is, haha) Thanks, Brock

    Modular Hobby Cell Battery Pack Design

    Ya looks like some redesign is needed. I will likely get rid of the spacers. I designed the pack with Southern California summers in mind, hence the need for cooling. Perhaps a blend of the ideas here would be to first off have all bricks tightly strapped together with plenty of protection...

    Modular Hobby Cell Battery Pack Design

    Dogman, Yes I think you are right, I can stop them from chafing by shimming them up with foam tape so that they do not move. However in a crash there would be lots of pressure at the point where the delrin contacts the cells. I do have extra spacers so I think in light of this I will use 3...

    Modular Hobby Cell Battery Pack Design

    Hello, I have been building a modular battery box for my eKart, and as the design has progressed I feel that it is something that is easily replicated by others for karts, atvs, and motorcycles. A bit over kill for an ebike though. A little about the pack, I am building a 36s5p pack with...

    3-192S Arduino BMS (using BQ76PL536A)

    Any updates? I am interested as I am running an Arduino based ev computer on my eKart. It would be for a 36s setup. Thanks, Brock

    methods LVC/HVC/Parallel -> documentation thread

    I agree not worth the risk. Because of this messy situation I have redesiged my pack to be less like spagati junction Lipo. See post number 80. http://www.diyelectriccar.com/forums/showthread.php?p=359246#post359246

    methods LVC/HVC/Parallel -> documentation thread

    It was on the balance ports for the packs, I assume that the packs were trying to level to one another, even though they were only a couple of milivolts apart.

    methods LVC/HVC/Parallel -> documentation thread

    If I plugged my HVC boards in before, I paralleled my cells, and got a tiny arc, did I fry the boards?

    Turnigy NanoTech last cell in pack always weaker?

    So I wired up an adapter like you said with the Red to the 9th wire instead of the 7th (skipping wire 7 and 8) and I got a bad cell count, double checked my wires and they look right. How exactly did you wire it? Thanks, Brock www.winzeracer.com
