Yea. I have not lost a pound in almost two years. Back in 2019 before COVID19 I went from 234 down to 215, I was going to the WMCA.
I am back to 230. My diet is horrible. McDonalds , Stromboli's and calzones and fried chicken sandwiches and fries at Wendy's all the time.
I might get the wife to bake some chicken or do a stir fry meal with peppers and mushrooms and left over chicken or 93 % lean beef but I like cheese on it.
It says cheese is ok in small portions though so sprinkling a little on the top of lean meat and veggies is ok but Stromboli's and calzones or 4 slices of pizza is not ok.
Anyway they got a new ordering thing on the wall and a 400 pound fat guy to show me how to use it so obviously he had no clue about the healthy menu choices listed above. :lol: I ordered a chicken burrito with no sour cream or cheese and rice under black beans. Not too bad but will be starving in about 4 hours. Hopefully I can get the wife to fry some fish with extra virgin olive oil. A lot healthier than the lard they use in fast food restaurants.
I need to cut way down on butter which I use too much of on canned green beans and sweet peas. I hope to lose at least a pound a week but this is most difficult for me.
I ran the 20" bike with the 13S batteries and has full power. Runs perfect. The same bike the 10S - 8P packs failed on yesterday. The 10S packs are completely shot. I had to beat a thunderstorm home. Really dark clouds moving very fast. I just made it and felt a few drops on the way in. I figured there would be lightening bolts and thunder but that storm is gone. Just white sky now with no sun. Somebody is getting hit I bet.
I am really not sure what to do with those 10S packs. I still do not know if one or two packs are bad and one pack is good if there would be such power loss I experienced yesterday. All three packs tested at 42V and internal resistances were all about the same. I am at a loss for words on this. It really does not make any sense to me at all.
All I know is if I run 36V LIFEPO4 it will work fine for the Currie with the 36V 1,000W chain drive on the back but that is about it. Since 36V of LIPO4 fill up two of my battery boxes there is no way I am running them on the 26" dual suspension as that rear hub motor really needs at least 53V to get any usable performance out of it.
Also I really did not want to run 36V LIFEPO4 on the 26" Diamondback with the dual Bafang motors. The 36V - 8P pack was perfect as they fit in one black box. I do not want to modify the rack for two side by side like I did with the 26" dual suspension.
So now I have a total of 7 - 10S - 2P hoverboard packs including the old SONA and Samsung packs and a 10S - 14 Ah Laudation pack that I do not know what I should do with. I can unhook the old hoverboard packs and test each for internal resistance but not sure if it will tell me anything as the new packs that failed did not tell me anything as I just do not know what to do. I just want one 10S - 8P pack in one black box for my single and dual Bafang motors. I will run the 36V LIFEPO4s exclusively for the Currie.
I hope someone has some answers.
Thanks.

Yea. I guess it is like I figured. Lion is just junk. Garbage. All three packs tested at 4.2V and held a charge but are still shot.
Paid way over $200 for those and did not even last two years and nobody here even has a clue why. I do not understand how the packs can be bad if they charge to 42V and hold the voltage. Also do not understand how they could be shot under 500 cycles. Ok. 48 months * 4 weeks = 192 cycles if I ran them once a week so taking into consideration rainy days and winter weather probably an average of twice a week so somewhere around 400 cycles and all three packs are totally shot.
Now the old hoverboard packs probably exceeded 400 cycles back in NY and then ran them at least 200 cycles here in Ohio so somewhere between 600 and 700 cycles for those old 10S - 2P packs that I put in parallel for 10S - 10P. I just find it difficult to believe that I have to recycle 180 - 26650 cells or 7 - 10S - 2P packs and a 10S - 4P pack. There should be a way to at least salvage 1/3 of all that or 10S - 6P. I just need to run Dual Bafang motors which is 17 amp controllers so 34 amps total. 700 watts.
I just do not know what I should do. Is it impossible to find out what packs are good and which ones are bad without tearing each pack completely apart and testing each individual cell ???????
If that is the case I do not want any more BMSs unless it is Bluetooth and can see each cell voltage and iR on a phone screen or something. This shit is ridiculous. I am irate.
Thanks anyway.

I think I said it awhile ago but I got to be in the mood to solder and I am not. The last pack took over a week to build and many hours. Then I got clowns saying it will burn up. Before that I built them all wrong and had to tear them apart. Before that I ordered a spot welder but when I got it was too scared to plug it in. Nickel strip has been at the post office for at least a week.
Then I get people warning me about a fire and nobody said it even might work so don't really want to build the second one right now. I spent way over $1,000 on batteries and only have one working pack. The 13S - 20 Ah pack.
The corner of my closet is batteries. All 180 cells in the cans Seven 10S - 2P hoverboard packs. 24 LTOs under them and LIFE packs I screwed up and need to get ready for re solder and a bunch of different 18650 combinations and at least 150 loose cells and got the two power modules on the kitchen table.
It is just hopeless.
Thanks.

I cleaned up and organized the e bike workshop. I bought that speaker wire the last time I rode the 26" Dual Bafang and those packs ran perfect. Then a week later they are shot ????????
I can not work with that 10 gauge wire from Home Depot. It falls apart and breaks. The 12 gauge Wall Mart wire is almost as bad. Not flexible and have to take a lighter and soften up the insulation. I will use three strands of the 16 Gauge and should be around 11 or 12 Gauge. I have a 40 amp breaker so will be good for that but not the 3 kilowatt brushless motor.
I will need 12 - LTOs , 8 gauge wire and a DC booster. I plan on boosting from 30V to 56 or 57V. > 2,600W < 3 kilowatts- 44 or 45 mph gearing.
Each 16 gauge wire strand will do 15 amps and 600W so three = 1,800W so perfect for my 1,800W brushless motor and four for the 3 kilowatt motor as good for 2,400W. 2,600W is maximum but wont happen for maybe a few seconds. Cruising speed will be 35 mph. Top speed for under 30 seconds 43 mph. Four strands of 16 gauge wire but might be able to use the 10 gauge wire as will only need an inch stripped for ring connecters on the LTOs.
I will be using three strands for the LIFEPO4s. The first pack was = or > three strands of 16 gauge wire.
I measure the first wire and leave about 1 -1/2" for series connection then solder each wire from the 5 cells to it and then cut a piece of wire double the length of the first wire and wrap around the whole thing. At least = to 10 gauge I think so good for 1,800W.
The second will be the same but hopefully better solder joints and even better series connections. I did video and took pics. of the first pack and will do the same for #2. Hopefully there will be noticeable improvement.
Thanks. LC. out.
