I suggest we all pitch in and buy a bike just to dissect and try and reverse engineer. I'm pretty confident in my judgement and abilities but there are some components on my personal bike I'm not prepared to risk poking and prodding too much in the search for knowledge. Not sure how to handle...

I'm in. I recently tried to "de-lid" the host processor to check out what chip they're using but Alta's got that thing pretty well glued together. Damn! However, I'm pretty sure they're using CAN FD J2284-5-2016-09.

I'm really surprised that the executives at Alta would depend on a funding agreement between parties where one party could pull out so easily or without substantial (enough to continue operations for months) penalties. That's just cutting things way too close and poor negotiations. These...

Yes! There's one input line fuse. Looks pretty standard. The output looks to be controlled by a 10 amp relay which in turn is controlled by the CAN comm link (twisted green/white wires). If the proper command from the bike is missing the relay will not close. Check your charger-to-bike...

The pits looked like a FastHouse effort as opposed to an Alta team. No "Alta" truck, tent or signage to be seen. A few guys hanging around with Alta tees but that's about it. DD qualified 14th or 15th out of 18 riders I think. Unfortunately, he gated against Mac (the eventual winner) on the...

You might have to open the thing up and look for a fuse on the output side. There could be several, one for each voltage. There's probably a comm (CAN) link as well. Be Careful! High Voltage.

The deeper I tear into my Alta the more I'm convinced that most of the physical tech is readily available. Much of the electronic tech is also commercially available. Of course, most of the hardparts (suspension, wheels, etc) are all available. However, the trick is to seamlessly integrate...

It makes the most sense to be bought by a company with interest in Husky/KTM. Think of the cost breaks they'll get for such things as Wheels, Suspension, Brakes, Controls, most everything except the frame, powertrain, electronics, and of course the battery pack. If so, I predict a...

Well, that explains the lack of availability of certain components like the battery pack. You can't stock expensive parts like that when you're struggling or don't have a firm financial plan forward.

I believe It'll work on a 18 if you use a slightly shorter link but don't quote me. I use a 15/earlier KTM TRAX shock and link on my 17 (it's a bit shorter). Yes, the TRAX shock requires a bit of grinding in the area around the upper eyebolt. No big deal, a big file will work fine, just go...

Does the bike function properly with the display disconnected? I'd check my bike but my pack is torn apart right now.

If you race MX (or any format where the pits are tight) you need the quietest unit possible or you'll suffer the wrath of your pit neighbors! After some mods my Q6500 is much better in this regard, but it can still get on folks nerves during a long day. The big (expensive) Hondas and Yamahas...

A 5.7 rear sounds very light to me. I'm only 150lbs and the stock 6.3 (2017 MX) seems light! I've chased rear spring rates for quite some time now. The lighter springs work out better when it comes to setting race/static sag the traditional way but in my experience (both riding and through...

Those particular cells have not crossed my radar screen so far, I'll take a look. The only difficulty in cell replacement is wire bonding to the PCB. The tiny little connections could be from several "non-fusing" process. Ultrasonic possibly, but probably some kind of parallel gap welding...

Not without cutting one out and bench testing it (assuming the Mfg identifiers have been removed). However, I did note that the Positive button has an unusual vent hole configuration. Three rather large symmetrical ports. I've tried to match it to pictures of known cells but I just can't...

I'm using ANSYS to model and run thermal/electrical simulations at the 1) cell level, 2) "mini" module level (14 cells) and 3) 1/2 Pack configuration. As usual, finding and/or developing material, component, and contact specifications for thermal conductivity, specific heat and in some cases...

I'm pretty sure the higher C rating would just delay the initial onset and after the first hard "ride/charge" cycle they'd be heat soaked as well. Typically, cells made for higher C rates are more thermally conductive, probably the reason for the improved performance of the MXR pack. However...

I'll run some trades to see what makes the biggest difference. The copper heat sinks are heatpipes, or probably more accurately "vapor plates". In this application they help even out the local module temps by providing a better thermal path for the hotter "inner cells" to reject their heat...

Kinda interesting how Alta documents certain assembly process like this Cell Module. Only two days to bond, assemble, wire weld and test. Not too bad. Each of my modules were serialized, 1961, 1962, 1963 and 1964. Up to almost 2000 units of this part number early this year!
