As the Hub Motor Turns and the LiPo Fire Burns.
Yea.
I hope SUNDER will post again. I am glad to see he is doing ok. He was here for the first few pages of this post about 6 or 7 years ago now. He sent me my first hub motor.
I just finished my final soldering video for awhile. I will probably solder again but not any time soon. After I finish the pack I will be running the 20" bike with the 1,800W brushless motor and then the 26" dual suspension.
Here is the video.

Hopefully by this time tomorrow the 4S - 5P - pack will be on the charger.
I had to balance charge at 6S yesterday as one 6S pack was at 99 to 98% and the other 90% to 96%. I guess I will go ahaed and order two 6S active balancers and a 4S active balancer. That way I can just charge and let the balancers do the balancing automatically.
For my 36V - e bikes I have my 10 amp 43.6V charger and when I run 48V e bikes my 54.6V - 15 amp charger,
54.6 / 16 = 3.4V. That will be for out on the road when I need to re charge to get home. At home I will properly charge with the 12S - 43.8V and the 4S with my 6S - LiPo charger on 4S balance in LIFE mode.
Also for the Currie I will be ordering a 60V DC breaker for that 40 amp brush controller as it tripped the breaker twice last time I run it. That is why I hooked the wimpy 26 amp brush controller back up. Also with a separate DC breaker for the 40 amp brush controller.
There is the first video with the Currie and 26 amp brush controller and Bafang up front.

I later hooked the 2 kilowatt controller and went the same route.

To switch controllers all I will have to do is unhook the bullet connecters connected to the two motor wires from the 26 amp brush controller and plug them in to the 40 amp brush controller. I wont have to unscrew the terminal from the DC breaker.
Yea.
My soldering skills are on point now and will be working on mounting batteries , controllers and building the LTO packs.
Also the 26" dual suspension. I ordered the 11T - 17mm dual D bore motor sprocket for the 36V - 750W gear reduction motor. It will go on the front of the bike with a 48V - 1,000W controller. It will be a beast.

Yea. I got woke up by code enforcement. We got 30 more days. The landlord will be getting a big fine and in 30 days criminal charges if nothing is done. I am not paying rent so will save my money.
I just did a video on the last 1S - 5P pack. I will soon be combining for 4S - 5P so can do 16S - 5P.

The videos clearly show that I am a master battery builder now. My method is way better than any factory spot weld deal. It will easily push 40 amps continuous and 60 amps peak. Probably a lot more. Those numbers are modest. Looking at between 2 and 3 kilowatts at 16S. Remember I already hit 2+ kilowatts at 12S.
Looking at ordering two - 6S active balancers and a 4S. Then It will be simple plug and play. I wont have to be bothered balance charging or hooking up external balancers.
Yes. Everyone here on ES will have to admit I Latecurtis am a genius. The power meter and GPS speedometer will soon prove that when I shoot a video running 16S - LIFEPO4. > 2,500W and > 30 mph.
I really like these. A lot more capacity.

Yea. Just under $300 for 90 cells.
18 * 3.6V = 64.8V. Should be less SAG also as higher capacity cells. 5P = 30 AH. The LIFE packs I just built are < 20 AH.
The K2 energy cells I bought are out of balance as been sitting on a shelf at a military compound for years and years. They might be military grade but are ancient. I now know it is not my building methods.
If I do order those I will build them exactly like I just did the 4S - 5P pack. I admit I cut a few corners on the two 6S - 5P packs. There were a few cell banks I did not solder like I did the 4S - 5P pack. I just covered with the liquid tape. I regret that but am not tearing the 6S packs apart. It could be the cause of a little voltage loss but the active balancers I ordered will make those packs absolutely perfect and good for at least 2,000 cycles.
Yea.
I really want to order 90 of those bad boys and build me a 18S - 64V pack.
Thanks.
