Some of the throw aways I have gotten are your 30 and 40 Amp hour batteries, so they have a decent amount of cells in them.  The hospitals change them all out pretty much in a group, so realistically, even though you may have to tear apart 4 batteries to make 1 bigger battery, all the cells, are probably about the same in the amount of use they each received. 
Ive talked to the techs who actually did the change outs at the hospitals, and he was saying that many of the batteries, the system is on the grid, the battery is just in case it went down, the hospitals also have emergency generators too, so IN the rare case it was used, it was only for a minute or so, so they are all essentially like brand new, but the ins company makes them change them out for liability reasons, so out they go !

Hey Aaron, do you want a pallet load of 33 Ah Lithium Batteries, each one has it's own built in BMS.  Max amp draw per battery is 40 amp.  F-K yeah Ill take that!!!  Lead acid recycles,  Lith FerroPhosphate does not, they are more than happy that I take these off their hands.  Worse case, drain them chop them and chunk em, Ill recycle the nickle for a few bucks / lb.

For those looking for cheap batteries.   I often get a LOT of decent/ read really good condition batteries from places like the Batteries Plus stores.  Hospitals and other critical demand places have to change their batteries out on their Defibrulators / Cardiac maches and other critical equipment every few years at most, whether it's good or not, CHANGE IT.  They take the batteries to these stores to get rid of them.  So you have access to lightly used, WELL taken care of Lithium batteries, for essentially free.

They don't always have the LiPo's but DO have a lot of higher ampere hour demand Ferro chemistries, so unless you need a ton of amps for the bike for blistering speed, one of these might work super well for you also and are typically rated for stupid like 5 to 8 k cycles from the manu.

Just talking out loud, might help you find batteries if you need to get some to play with / test your bikes with.   Invariably they get boogered up every now and then, and it's nice to have a source of cheap replacements.

Thanks for the info. This is an interesting option that I never knew existed. The challenge may be getting enough cells of a similar type/size to make larger packs that can be balanced. That said, if they are consistently "lifed" then its likely that cells of the same type would have similar remaining performance. If the price is right and you are able to match a stack of them up then this could work really well.

In the winter of 1986 I  built a TZ500KZ - a TZ250 road racer chassis with a Kawasaki KX500 two stroke 500cc motocross motor. It raced in the Pacific Northwest road racing series in the open single class. I raced it and won several regional championships in British Columbia, Washington State and Oregon. I wish I had the design tools we see here. It would have been even better than it turned. I am so impressed with your project and how thorough you are! I am glued to your channel.

Thank you for sharing.

Your build sounds like a lot of fun. I've never ridden a 500CC 2 stroke but can imagine how that would have gone

CAD and 3d printing and prototyping services have certainly made one off builds a lot more accessible for DIYers with a basic home shop. Thanks for the sub!

so you go settings > electric beat

I don't think the vehicle will need an update but I can't confirm.

  Fords needed an update. I know that as a fact as many tried to charge on the first couple of days that Tesla said they were open, and they wouldn't charge. Then they discovered the update was needed. I think it was done OTA, but that I am not sure about.


I assume from that, it was the same with Rivian.

Rumor has it Stefano and crew have been seen meeting at top secret R&D charging labs to ensure full compatibility.

Let's hope that is true, but then we will (most likely, IMO) need that FW version 44.

Actually that *does* work. Daren tested it at a SoCal Magic Dock station. Used the A2Z adapter and it worked perfectly.

Interesting. I wonder what the difference is between those V3s and other Tesla V3 superchargers.

And I hear there are two reasons, Tesla has to has to open theirs up (the V3 & V4 that does NOT have Magic Dock) and the vehicle itself will need an update. Perhaps that will be Energica's V 44, someday.

If I use a Tesla Supercharger that provides Magic Dock, but I use my own adapter instead, will it work?  I assume NOT, unless there is a way to remove their adapter and use mine. IOW, "charge your non-Tesla" does a lot more than only provide an adapter.

Man you *really* just don't want to believe me when I tell you that cannot happen until Tesla opens up their network.

I really don't want to believe anybody about such bad news. But thanks for the bad news anyway, as you were to first to explain to me that it wouldn't work. Notice in the above message I did say "I didn't think it was possible."  Besides, as you know, I already have a couple of Tesla SC to CCS adapters and I tried the Tesla V4 SC in Sparks, NV and it didn't work.

Magic Dock obviously does it much differently, it's more than just an adapter that fits. Now I have a question for you . . .
