I just sent what I had. Good luck. It might be tougher going across the border with one.

I had heard something good like that. I paid 8k. Only 14th miles. Seemed like a pretty good deal. Very happy with the car so far. It's range is very different at 25 degrees for than at 35 degrees f. Some thing to do with battery heating. I would probably like the orange and black. It...

Put about 5000 miles on so far. Just decided to move into a more modern EV . Bought an i-Miev.

I've put around 2500 miles on the car. The batteries are staying very well balanced. I have one 48 cell Fetcher Goodrum BMS assembled and once a week balance each 48 cell group.

They don't shut off at the desired voltage, but when the battery get to the voltage that the charger puts out, the battery will stop drawing current. You have to have a model that current limits. Then it will constant current charge up to the set voltage. There are higher voltage power...

My new 200v ev charger. 8 - 24v meanwells. The 7 320w don't current limit, they only do hiccup mode. The 200w has current limit and limits the rest. Paid $25 each for the SP-320-24 on eBay.

Perhaps take an EV and add a gas engine. I'm thinking of a Solectria E10. It's a Chevy S10 truck that they have turned the differential facing back and added two electric drive motors. Could replace one electric with a gas.

I guess I should ask if anyone is not using the end 8 cell balancing section of their boards, I could use them.:-)

I could use 2 boards if the 2 parallel packs had each cell paralleled. But the way the packs are, only the groups are parallel. I suppose I could combine the balance leads so I only need two boards. Something to think about.

To clarify, I am not going to use the charger portion of the board. I am only going to use the cell balancing and take to lvc and hvc signals to my own circuits. Lvc will probably just sound a warning and the hvc may shut off the charger, depends on if I get a new charger capable of that or...

Right, I should have mentioned that my car has heat pads in the battery compartments. And the charger is smart enough to not charge until the temp is above a preset level. It has temp sensors on the battery terminals. It has thermostats on the heat pads. They run off the charger mains. I just...

No, I have no plans for cooling. At most, I might put a fan on the openings. The data I've seen, I shouldn't have a heat problem on what I'm drawing.

About 4.5 hours to recharge on 230v 15 amps

Just did a capacity test. Started at 4.16v down to 3.53v and got 38.87ah. This lines up with the test data I got for Josh on his pack. He tested his from 4.25v down to 2.7v and got 44.4ah. So I think my pack is close to the rated 45ah. 30ah should get me to work and back if I for some...

Got the two groups I've been driving with ready to turn on their side. Used metal shipping banding to wrap up the top. The one didn't have the original metal band as I reduced the size. Ran the banding through 1" aluminum tube (which I wrapped with electrical tape) and 1/4" rubber to build...
