more news. i'm starting to get jealous of myself. today's a holiday in US so i had some time to cleanup the garage and put up a new peg board:
here's a vid from yesterday of the balancing function, which i thought i'd already uploaded. i'd had it set to balance starting when cells were 3.6V, which basically means all the time...
[youtube]F1CHFb56Ek0[/youtube]
then i talked to andrey, set it to start balancing over 4.17v/cell, and wired in new connectors to charge while controller connected. and do some test runs
[youtube]DMxW4zz9bHo[/youtube]
then i ran an errand and plugged in the charger:
i had to go slow on the errand cause i realized the axle nuts weren't tight..

I am blown away by that controller, that is so great.
now just a low profile circuit breaker (ie http://www.ebay.com.au/itm/CIRCUIT-...T-SELF-TEST-/280594931926?hash=item4154c2e0d6) and some andersons with a weather proof cap on them for charging and you have a fool proof system. I am very eager to hear the comparison of power in boost compared to what you are used to with the infineon.

btw, in my little vid, i made it sound like the settings on modes were fixed. they're not! they're easily adjustable from Power Profiles screen that i showed...
i'd been wondering how i was going to use my 3 speed switch. i don't need to. i just push the Up button on the display to cycle through power modes.
now i just have to figure out how to have it startup in 'boost' mode.
if i can't do that, i'll just configure 'eco' with 80A batt/180A phase, and set boost at 20A/50A...
i'm glad i'm taking my time with it, and am amazed at the depth.
and i haven't even gone through the throttle linear configuration.
and with variable regen coming up as soon as i mount the magnet?
i do need to pay attention to the heat of the controller in that location tho, if i'm maxing current. i'll have to rig up air flow that can be closed in the wet, or go back to this:
you gensem will want the maxE, and honestly, so will i probably before long. but we'll get to speed testing soon enough.
i wish my rear wheel was more true. i might need to check the bead seating cause it's definitely whack, and i've got some frame testing - big jumping - before i'll feel confident in that.

the bike wasn't quite stealth enough to make it through the check point! i've gotten through in years past. plus we had extra crew who didn't have bikes. so we walked... and they moved the check point on us! used to be able to stroll up back of lincoln memorial and grab a seat on the steps. instead we acted like zombies in the fenced off prison yard until we found a high spot near the bridge..Trackman417 said:

i love how the tire makes more noise than the system.
took head mounted gopro footage too but it was pointed too far down.
hit 46mph easily on downhill stretch. batt case not secured however and unnervingly clonky sounding.
gotta check peaks but i saw 6kw+ at one point.
power completely cut at one point, and display showed !BMS!, and i was worried i ruined it.
unplugged pack and it must have reset.
i ordered turnigy 4s packs to replace magyver crimped packs.
i really want to go 3p (17.4ah) for range but you see my challenges fitting 2p. little 4s packs would have been eaiser..

So how hot did the controller and motor get? If everything is more efficient then things should runner cooler or more powerful for a given temp. 6k watts on a 3540 is pretty impressive. 6000 on my 4065 will throw me on my back. We need temps!

This prototype of box looks good. But, if I can say something... Cordura style was more silent. In first look its looks like bicycle frame bag... Now the main question. Is this all setup more energy efficient? Is positive difference to for x.e. infineon controllers? Please send too us few words on this topic.
Regards, Mike

opened the motor to switch temp sensors..
there were two white wires on LM35 so i scratched one w/ a razor (top right) and checked continuity with hall connector temp sensor wire before cutting:
misunderstood andrey to say i could use any other wire and mistakenly used + line from LM35 on one side and temp wire to other side of new KTY84 thermistor (supplied w/ kit). using + was a mistake, and i later switched it with GND, and finally saw the correct temp in the display.
pushed the thermistor up and under/against the winding, held it with a toothpick an buried it in jb weld to hold it in place and insulate it from corrosive waters.
and if you recall from vid, cell 3 on board 3 was not balancing, and indeed was getting too high:
andrey suggesting switching board 3 with the spare, that i'd toasted a couple connectors on. by last night, one cell was 4.09 and another was 4.02, while the rest of the packs were at 4.05. so i removed bms board, balanced charged the cells on that subpack to 4.05:
after the subpack was balanced, i reprogramed the bms board to [03], reattached it to bms board string, and charged via bulk charger up from 4.05 to 4.17. at the beginning, the max delta was .013 v and after 10 min it was down to 0.008 and decreasing.
to be clear, the bms boards are still in beta, but the fact that this thing actively balances at whatever cell voltage you want it to start, while sitting on bulk charger or whenever is pretty frigging amazing!!
now i just need to waterproof everything to commute because it's been raining every day for months it seems.

i'm not sure AJ's gonna like the rake or trail of that fork...
i understand those were very tough to ride! let alone like that.
i've been dying to commute in on the beast but it's been raining everyday and we're not waterproof.
temp gauge is working great. weird to see it in F:
much as i love my glass enclosure, fitting the batts in was a pia, i didn't like how they lay, and the heat of the bms concerned me. i want them visible, and i want the packs totally fixed during jumps etc, so i'm back to this for now:
the sharp innner edges don't touch the packs anywhere, but i taped over them anyway:
done in a hurry cause i thought i'd ride it the next day:
pack ain't goin nowhere
the bottoms of the bms boards seem a bit sharp, so i taped down all the big wires:
put a sheet of lexan underneath each set:
used some clear tape on top, tho i'm not sure how that will do:
and didn't have the proper size worm clamp to mount the controller below the top tube, so stuck it here for now:
just gone back and forth in the alley and it's soooo sweet. my bro came by and i let him try in eco and normal before he almost crashed it in boost.
i'm rigging up the variable regen now, fiddling with the hall sensor near the brake lever - and that's gotta be waterproof.
this next week at work is going to be hell for me, before the annual WI vaca.
we'll be six in the van with the mother in law this time. should we drop by, thud?

Why don't you put the controller in the triangle? You spent enough money on it, mine as well keep it safer from the elements. Keyword: safer lol

Damn now I feel like a complete fool 
. I remember reading that!
Are the bms boards still getting hot when they are balancing? I believe as you cycle the cells in, they should be getting more and more in sync with each other. The bms boards shouldn't be doing much balancing after the first three or four break in cycles.

Excuse me if I skimmed over this, I know you said you can set the balancing voltage theshold but is there a facility to set the delta V before it starts balancing ? That'd be handy from a heat management point of view if you could set it so it doesnt start to balance until it's more than say 0.02v different. Worrying about the balance any less than that is silly. I guess you could achieve this by setting your charge voltage to say 4.18v/cell avg and then not set the balance voltage to the same.

i was just thinking about an idea to make your garage safer after the fire, and i was working on a construction site and there i see some sprinkler ...you know that a sprinkler sets off at a certain temperature and that s all the mechanics about it...maybe you could setup just a big 5 gallons of water on top of your bike and a hose going down close to your bike and if there is a fire the heat will break the glass of the sprinkler and water will stop the fire
just an idea
edit : someone wrote me a pm saying water on electric fire is not a good idea well i am not sure what would really happens a fast 5 gallon of water on a open flame ...maybe just stop the fire, maybe someone would like to try it see what it does on just a couple of cells

i wondered the same thing. i spoke to the oracle and the oracle responded: not in the beta version, but note taken.Hyena said:
charged up this morning and after 1/2 hour:
just testing the hall/magnet alignment on the brake lever for variable regen:
going ~30mph and hitting brake, i get -10A. :wink:
roads dried out and actually took it for a ride today.
see motor temp. was a 255F before i took the pic, but something tells me that's lower than 200C:
i noticed the fuel gauge (bottom left) said 0% tho and decided to try to set the power range; asks for distance and Ah, set to 6mi over 4ah - just about like my commute so i said ok...
but the motor was also getting hot and i suddenly didn't have the same amount of power. was it managing power based on motor temp?
NO. it was just the smart range setting -- it obviously manages power/consumption smartly for you so you achieve the range! awesome!
okay, turned that off..
decided to do a bit of testing in some familiar territory:
[youtube]lnadpox0VLU[/youtube]
definitely need to get my feel back for the bike. felt different.
rear wheel be needing a major true too, tho i know i don't have the spoke threads to do it.
i can't tell about the rear suspension. seems iffy, and too be honest, the front sounds springy - it's definitely not what it used to be, despite the rebuild.
