Here's 2p of engineering anecdotes as well ... batteries don't actually benefit from having the huge gaps all down their sides for cooling, because the main part of the battery does not in fact get very hot. It's the electrodes that get hot, right at the tip. That's the only bit that actually needs cooling.

Well yes Princec you're right that is the "best" way to cool them.  Lucid has a video showing their cooling plate just on one end where both the + and - are connected in their pack.
But the first Teslas had liquid filled ribbons going around all the cells' sides in their packs because it's better than nothing.

The Energica overheating issue after riding and trying to fast charge over and over aka touring is well known.  The pouch cells packed in so tight made the issue unavoidable.  Just ask an owner.

Fun fact:  That's why Morgan kept his old SS9 so he could fast charge it more often. He knew the problem all along but didn't let that stop him from collecting commission checks by getting others to buy them and only disclosing that fact when he was outed.
What a little scamp he is.

Maybe the Singaporeans can fix that issue or they may just end up putting the Energica name on little scooters.  We'll see.

Here's my post from Sept 14th 2025 about Jr Vetter

You can always tell when Morgan gets it wrong.  He's a gas lighter and tries to talk about anything other than what was posted.

I know you will keep proving me right.

Hey remember when I sent you that clip of Shane McMahon jumping off a steel cage through a table when Ideanomics first bought Energica and told you that was what he was going to do to the company?
 
That coming true so quickly still makes me laugh.

By the way why didn't the CRP Group buy back Energica at it's fire sale price?
Was it because it was a huge money pit, losing thousands on every bike they sold like Electric Terry pointed out?
The vision of green credits being auctioned off to the highest bidder didn't pan out I guess.

I await your next childish insult post with great anticipation.

I sold my SS9 and now have an SS9+ RS. I sold bikes for Energica and collected commission checks on them because they literally did not make the 13.4 models anymore and STILL the coast to coast record is held by a 21.5 Energica. There is no conspiracy, but by all means keep searching for one. It's nice to have a hobby.

how about you two get a hotel room and just fuck each other already?
it's so obvious you both want each other, good god.
maybe after the 20 second romp is over you both can lay back smoke a cigarette and talk about electric bikes...

While trying not to picture EMF members getting hot and steamy, it got me thinking about heat and that I recently did a full day in the saddle of an experia. Left home with 40% and fast charged three times, with the battery only going yellow briefly despite the 35c temperatures and constant speed north of the 100km/h. I reckon if there was sufficient charging infrastructure, the bike would outlast any rider, which leads me back to the correct topic, Damon's SHIFT would be brilliant for long rides and what I was interested in. Being able to significantly change the rider position periodically would stave off soreness and really would have been beneficial changing from the head up in traffic mode to head down carving.

Yes the Experia improved on the over heating issue.

I think there were problems early on with the hand shake with some CCS stations but maybe a firmware update helped that.

The more I think about it the more I realise that the only thing holding my Zero back from being excellent is DCFC.
If Zero don't pull that out of the bag within the next 12 months they're doomed.

The one thing i noticed on my ego, which is a significant issue imo, is the black composite / plastic they use for the fairings, covers etc.  is basically an oven / heat trap.  Something about the composition of it, it traps ALL of the sun's IR and converts it directly to heat then keeps it up under there literally cooking the battery, inverter and whatever else under the gas tank area.  Seriously in the hot sun that thing can get up to 155 degrees, hot enough to burn your hand on.  I actually have contacted some other manufacturers of other electric items over this (ryobi) and they changed their composition a bit because of cooking the battery in this manner.  This of course was after many back and forth discussions with their engineers etc etc.  but anyways.  The black bike fairings, its like a solar oven, the sun heats it up, the batteries are inside this stuff, and if you are charging, there is no air movement, the batteries are literally going to bake in that oven, from the suns thermal load and the amp heat load.  no air means no cooling. means your current eventually gets limited.

my solutions were a, put some sort of air on it, a box fan blowing across the batteries helped tremendously, but you can't always take a box fan on a trip with you so B, toss a white sheet or t shirt or something over the black plastic parts and sides there.  Just that little bit of a gap, where the sun is beating down on the white sheet and reflecting back and NOT beating down on the black plastic oven sides of the bike, getting trapped / converted into heat and stewing the battery.

the battery is air cooled, you can't cool it down when the sun has the air under the plastic heated up to 135 degrees.  i know this sounds silly but give it a try.  it's getting later in the season but take an ir thermometer and meter bike temp sitting in the hot sun, then battery temp under that.  now try that next day with similar sun with a sheet ,or jacket, or piece of cardboard... it don't matter. just something blocking direct sunlight, and now see what the temp of the battery / air under fairings is.

as little as 3 or 4 C can mean throttling or not.   
remove the heat with airflow
keep the heat off / out with covering.
