Re: Tesla Cells for sale as wrapped or welded packs

So what kind of sag do you get a 20 amps. I thought those maxed at 10 amps? What cell is this exactly since I’ve never been able to figure that out? Panasonic what?

Re: Electric Track Racer

11 amps would be fine and 18 amps doable but again, I think we should always plan for a maximum of 15 amps. By going to 8p you would drop your overall draw from the aforementioned 11 and 18 to 8 and 13.75. That would keep your voltage up, heat down, battery stress down and over all wattage much, muc...

Re: Electric Track Racer

VTC6 cells are not 30 amp in reality, they are move of a 20 amp cell. 30 amps they over heat big time. I’d recommend figuring them at 15 amp and going a minimum of 10p. At 4 or 5p they will sag big time. At 30 amps they sag .8 volts on a fully charged cell. At 15 amps peak it will live a long, long ...

Re: A123 18650 for sale

Makita packs are Sony Konion cells. The a123 cells are still good just not as light as lithium. I ripped many Dewalt 36 volts packs apart over the years.....many! I also ran the a123's for years. The a123 cells are 26650 cells though.....not 18650. At least the ones that came from the Dewalt packs. ...

That was a good video and great camera work to really get an idea of what it is, size of it and what it can do. Doesn't look like it would fit my 6'4" 210 lbs size though. Bummer for me.

Re: Adaptto Mini-E/Max-E Owner's Thread

Repairing a bad cell in a glue pack is worse than sticking your hand in a garabage disposal. Sucks big time. I've done it a few times and it never gets easier. My next pack I will only glue the p's together and the whole thing will be held together with tape and shrink wrap just in case!

Re: how to check date code INR18650 30Q

At bottom of page it says,

'What cells are currently known to not work with this tool?

The Panasonic-Sanyo GA, and the Samsung 30Q are both not currently functioning with this tool."

Maybe that is why it's not working?

Re: New battery pack build.....25R, 30Q or VTC6?

It would be a 195 amp pack. But if you look at the graphs on the 30Q they handle 15 amps as well as the VTC6....literally shadow the VTC6 discharge line at .02-.03 less voltage. Only thing is they can not continually handle the current past about 2.8 amps where the VTC6 goes to about 2.8 ish amps......

Re: New battery pack build.....25R, 30Q or VTC6?

As I wrote I have a QS205 3.5T being controlled by a MaxE and I peak at 200 battery amps. Day to day I might hit that once or twice to make the ride more fun. Average runs will be 100 amps at maybe 150 for super short durations of a max of 30 seconds. Even with the VCT3 pack I have I can't keep full...

Re: New battery pack build.....25R, 30Q or VTC6?

From the battery builder I respect most here that was what I wanted to hear. I kept leaning toward the 30Q but when the vtc6 went on sale it had me second guessing. I know the VTC6's hold voltage ever so slightly better than the 30Q but the 30Q seem to have less decay in capacity as the cycles start...

So it's time for a new pack and pretty sure I'm ready to order next week. So if I can choose from 25R, 30Q or VTC6 which way would I want to go. I read and read and always end up confused. When I compare the cells it doesn't really end up a fair comparison since I'll buy the cells to get the amps I ...

Re: Solder longevity on nickel

I agree....iron not hot enough and a little extra mechanical bonding can be achieved if you sand the area your going to solder.
