As the Hub Motor Turns and the LiPo Fire Burns.
It seems that all six of the laptop cells tested are > 1,000 mAh. but not high drain.
I tested two of the blue cells in parallel and since they were not high drain like the other cells I set the discharge rate to 600 mAh which is 300 mA per cell.
As you can see these blue cells could easily be 1,500 mAh so are probably rated at 2,000 mAh new.
I showed you that the green Panasonic cells were rated 2,000 mAh and posted a spec sheet. I just might order a bin of used laptop cells if I can find similar batteries.
My question is how large of a pack can I build. In other words new cells tested would only need 6 rows of four in parallel series to achieve 8 Ah @ 6S. How many rows for the same with used cells ? 6 rows of 6 maybe or 6 rows of 7 ? Six rows of 8 would be ridiculous.
It is somewhat confusing as if they are 2,000 mAh BRAND NEW and USED the capacity is between 50% and 75% does that require 6 rows of 8 or 48 USED cells to equal 24 NEW or would 6 rows of 6 or 36 USED 2,000 mAh cells equal 24 BRAND NEW 2,000 mAh cells.
The company who I got the fake cells from gave me a $15 refund so I ordered four more for one 24 cell 6S - 8Ah pack. I requested the same deal next month where if I order 20 cells they would send 4 free. They declined.
I offered to buy 50 cells for $150 next month. I told them 70 / 20 = $3:50 per cell was too much for cells which were not genuine and not 3,000 mAh above 3.0V. I said 3 bucks a cell is the best I can do next month so I will see what they say.
In the meantime am looking for better deals however really need more of the same for 12S. Unless I make the second pack from laptop cells. Please let me know. Thanks.

OK it looks like I got a BINGO here.
EXACTLY what I am looking for. If you read the description you will see. Even if the seller of the fake LG batteries makes me an offer I will be ordering these first unless DA orders them all.
It states that is the last of them. Only 100 cells left.
DA , SUNDER or DAN.
It says only $13 for shipping. That is $163. for 100 decent cells $1:63 per cell.
If one of you decide to get them before they are gone I can send a money order from WALL-MART next month on the 3rd for $75 + $10 - $15 for shipping 50 cells to me. It should not be more than $15 for shipping 50 cells if the company ships 100 cells for $13. Please let me know. Thanks again.
I just picked up a pack of Westinghouse cells from Wall-Mart. (see bottom pic) My problem is I don't usually have much to spend except for the first of the month. During the month I sell bike parts or computer parts and get like 20 bucks or 40 bucks from the ol lady.
Also the bottom pic shows the spokes Dan sent. I found them and Doug will be fixing the Hub motor on the Schwinn.
I might be able to afford like 4 cells a week for $15 close to $16 with the tax so am paying like $4 per cell. The thing is though I don't have to wait a year for them to get here. Building a decent pack from 18650 cells is taking way way too long. I have six electric bikes and only batteries to run two.
The SONA packs are going to stay with the 29" Hybrid bike (easy street) The old LiPo packs in the cash box are good for Wall-Mart or the grocery store. I need a decent pack for the Currie and little 20" cargo bike, Both are chain drive and not nearly as efficient as the geared hub motor which I run the SONA packs exclusively.
Therefore I need at least 48 - 44 volts at 8 Ah minimum, 10 to 12 Ah would be even better. Not sure how I will accomplish that though.
Right now I am 4 cells short of a 24 cell - 6S pack. The other 4 cells are ordered but definitely not holding my breath until they get here. It might be possible to grow a maple tree and sit in the shade by then,
I also have 6 used laptop cells all > 1,200 mAh. I also have four Westinghouse cells I will be testing tonight. They were already tested on you tube and were > 1,600 mAh. Please let me know. Thanks.
I build e bikes. There not always pretty or practical but sometimes they work, at least for awhile. Immortality is not a dream but the future of our evolution. We were given the tools to forge our own destiny. We were created in gods image and shall evolve to live forever.
