Very interested to see the temp differences on the motor with and without the liquid cooling, and compare your readings with the internal monitor temp on the 840 display.

(maybe a system of mirrors then...)

I don't want to take over Miz thread but it seems this might still apply to him. I've been puzzling over your response to my statement above and then I went back and reread what I wrote. I miss typed that last line. It should have said, "Also, wouldn't the stiffer CALBs mean that the energy capacity between 3.35V and 3.38-3.4V be even more than with the TS cells?"

If so, then my numbers will be lower than the same tests with CALB cells. In any case, I need to get some CALB cells to test and make a comparison. There is such a dearth of reliable data on these cells it is difficult to determine the best way to treat these cells under various situations and conditions.

Miz, Hope you can get insurance soon.

I am on my fourth insurer. Everything goes well until they see pictures....

I really think it is that they dont understand what they are looking at. They just opt out as not to seem clueless of electric cars.

My applications are getting more "refined". In this case "full disclosure" is not indicated or desired by both sides.

I need to calibrate the speedo this weekend. Then further information has a meaning.

And I thought the titling process was going to be the real challenge....

Gizmo, Jack Rickard has all the data, testing, and graphs one could want on the CALB cells, along with some comparisons to TS cells.

UPDATE:

I have been sitting here doing nothing while I searched for insurance.

The penalty for building a unique car is to be placed in the "odd" catagory by the underwriters. Everything goes fine until they get the 4 required pictures....OK...OK....OK...Whatthehellisthat!.... .

When they see the engine bay, they really freak. If they do not understand it, they are not insuring it. "We can not cover your car at this time".

So, I got more creative with each policy form I filled out. Not lying, just brief and as few words as it required. That and some carefully taken pictures. Take a ton of pictures, adjust the angle as to minimise the odd aspects. Select 4 from the collection that fill their needs without standing out.

So, I noticed the latest company has charged my credit card last wednesday.

The policy should be in the mail. (or so I hope)

Things that help:
Garaged 7/24.
Active alarm system in garage.
Driven less than 6,000 miles/Yr.
Proof of main transport vehicle/copy of title/copy of policy.
Show a main vehicle/title/policy for every licensed driver in the house.
On board Halon/fire system.

I got my J1772 plug installed on-board. Installed the "spoofer" board.
I made a charging cable for leaving at home. It has a power box and a contactor.

I have everything installed except for not connecting the signal line to the power box. I have a toggle switch to activate ths contactor.

I also need to calibrate my ZEVA device as well as my speedometer.

OK, The last time I charged my pack, they were sitting at 3.125 volts/cell. The ELCON started out charging at 127.5 volts and 12.7 amps.
At the green light, it measured 127.6 volts and 1.36 Amps.

Miz did you ever do the comparison testing to find out whether or not your water cooling setup on the motor is helping? I am toying with the idea of using a small, sealed, PM, motor to make my bike project move until I get a Mars for it and was thinking about trying this idea. I have the radiator and water pump for the bike so making the cooler would be just the cost of the copper tubing, and fittings.
