I tried to start reassemble everything, but the mosquitoes about ate me alive. I'll have to wait until tomorrow.

Re: Finally bought one

Hi, What are the dimensions of the sub-packs? Are you going to use the water cooling? Group 2 & 3: 24s3p How hard would it be to remove one or more 3P groups? I'll get dimensions for you soon. I'm thinking no on the cooling since I'm not going to use huge amps compared to the Volt. I'll monitor the...

Re: Finally bought one

Each cell is 15ah, each cell slice has 3 LG pouch cells paralleled, can't change that without destroying the packs. 4 groups Group 1: 30s3p 1350ah Group 2 & 3: 24s3p 1080ah Group 4: 18s3p 810ah 4320ah Total I can pair Group 1 & 4, and Group 2 & 3 to get 48s3p each. If I parallel them I will have 48s...

Re: Finally bought one

The shipping ended up at $363. That included pick up from a residence, lift gate on pickup, hazmat charges, and insurance. Not too bad at all. I used FreightQuote.com they were very helpful. Especially with the hazmat stuff. They also gave me a $13,000 line of credit with them. :shock: :?: :!: I dec...

Re: Finally bought one

Cover comes off with a million 10mm bolts. Was setting just over 300volts Entire pack was well balanced, every cell was around 3.1v +/-0.01 Got 2 groups home, working on charging one. http://i958.photobucket.com/albums/ae61/yopappamon/3ce6785eea0ea90bfeebd889404ecb20.jpg http://i958.photobucket.com/...

Re: Finally bought one

The battery is on the truck. Should be here by Thursday. I have found a guy who has already put a Volt battery in this same car. He said the weight reduction really makes the car perform. He only used 2 of the 4 modules so he has reduced the weight by over 600 lbs and gets over 50 miles range. I cou...

268 amps max.

15kw continuous shaft output power (@4000 rpm), 35kw peak.

I need to find out if the DC/DC converter can handle the extra battery voltage.

Re: Finally bought one

How much did it cost and where did Harold get it? I'm not sure how he found it originally, but it ended up on ebay before we had a chance to close a deal. $1,400 plus $360 freight. Still over a grand cheaper than new lead. Can you keep the entire pack? It would be almost 90% of the capacity of the ...

Going to go Lithium. Harold found this Chevy Volt pack and we are splitting it.

Anyone know if I can use the battery management system and keep the cells in their pack groups?

How would that work between the first and second ferment? Drain into a bucket, wash out the yeast, then put back into the carboy? Can I give the left ...

These cells aren't going back in the car. Any that I can revive enough are going on the solar panels.

Re: De sulfating SLAs appears to work

Just re tested one. First Time it had 17.3 ah capacity. Discharged it and recharged it, now has 22 ah. 27% increase.

The de sulfating one went from 23.7 to 36.1. A 52% increase

I'll cycle the 22ah one until is stablizes then de sulfate it and see if there is any more gain

Re: De sulfating SLAs appears to work

It is assuming. I'm trying a few other things too. The first one, I charged it fully in the car, then topped it off with my black and decker smart charger. Discharged it on a harbor freight inverter running a 600w heater until the inverter shut off at low voltage. Then measured the amp hours to char...

De sulfating SLAs appears to work

After checking the capacity of the gel cells that came in my Solectria Force EV, decided to try de sulfating one and see if it helped. Set my power supply's to 16 volts at 200ma, set the battery on a portable oil filled electric heater to warm the cell and left it over night. Almost 22 hours with so...

Re: SLA packs have longer cycle life stacked pancake style

It takes 13 batteries.

Of those one had an open cell.
Three had less than 1ah capacity
One had 50+ah
The rest had 15-25 ah

I'm probably going to try to go lithium.

Dnmun, what part number are your Deka batteries? I've just started capacity testing the Deka's that came in my Solectria Force. They are 8G28. I have one with an open cell, 2 more with no capacity and deformed cases. The first good cell tested with 51Ah. I used a Harbor Freight inverter running a 60...
