Previous E-Bike video http://www.youtube.com/watch?v=1J8t7Vipe2c Next E-Bike video http://www.youtube.com/watch?v=1e_gj4dASl0 schematic of my bicycle battery http://i1199.photobucket.com/albums/aa475/rinoa-heartilly/Astrolabe/battery35ah4.png here's a video showing how i made half of my new battery. the battery pack i built is 24v 35ah and i will built a second one to run with it. its just building two would be boring in this video and delay it even longer. if your looking for laptop battery packs to go to ebay and search "laptop batteries" then go for "buy it now" so you can buy like 15 packs at a time. organize the search for lowest price/shipping. and ebay even has an option to limit the search to how many cell are in the packs. and you should be able to find packs that are about 1$ - 1.5$ per cell. thanks for watching, this was a very rewarding project.especially going 30 MPH up those hills. i feel sorry for my battery on that test though haha. i'll be doing a distance test video soon, and then another when i get my 2nd battery block done. the battery should already be big enough for me to drive between towns instead of just in town. the song is from Rocket Power Beach Bandits for the playstation 2.

did you spot weld it?

thanks alt for this video dude!! :)

Hey guys. If u have a Batteries + Bulbs near u, i would suggest going there. I get about 10 laptop batteries each time i go. All for free.

Hey, I have been thinking of power my ebike with a 24v 18ah battery with a 20a 1200watt boost converter. It's a good idea.

How much Mileage for 48 v 24 amp in one charge
-
balance leads?

Good work.

Excellent video to watch education in one video have a good day

um isnt that battery s6 not 12s??

So I took a single 18650 cell and started to charge it. I was putting in 2 amps using a lipo charger and the cell was fine until it hit about 4V and then it started to get pretty warm and eventually semi-hot. Do your cells get pretty warm to hot when you are charging them? Was I putting in too much amperage? I tried doing the same thing this time using only 1 amp on a single cell and it had the same results, the cell got pretty warm-hot. I could still hold the cell in my hand but it was hot enough I was worried about it becoming liquid lithium and spewing fire lol. The upper cut-off voltage was set at 4.2V and I was using a standard RC lipo charger. I looked up 18650 cells on Amazon and all of them said a single cell could take 1A standard charge rate or up to 4A rapid charge rate. What would you recommend for making amperage for a single cell? Thanks for the magnet idea that worked great for me by the way!

you could probably get 30% more out of your cells if your measured each parallel section and added compensation cells to the lowest capacity ones

Hi RInoa,
Thanks for the awesome videos. Sorry if you already answered this somewhere but do you happen to know the discharge rate of these cells? 5A, 10A, 30A, etc. -
Did you use any battery management system?

I am trying to replace my ebike lead-Acid battery 24V 24aH with Lion 18650 cells. Once pack is completed, I suppose I can;t use my existing charger of LeadAcid Battery. Do I replace it with Imax 6 Lipro or similar..

I know this is an old video but when you charge li-ion with a psu then set it to 4.2v x cells in serie (12.6v) and set current to zero. Connect positive and negative from psu together and turn upp current to 75% of max charge current (4x2x0.75). In this case about 6A or less. Then connect it to your batterypack. This is the safest way to charge with a psu without lithium charge control.

What about a capacitor bank?
-
about batteries ive seen videos on youtube about laptop lion batteris if one battery is one cell with 2Ah then ten batteries is 10 cels 20Ah at maybe 25 30V so say my longboard motor at full throttle going uphill draws 10A then I can drive it uphill for 2 hours straight
-
what is the total weight of your battery pack 48v 24ah?

AvE has a cool video on a diy spot weld for lithium cells that is awesome. I figure it may save you time and be stronger/safer for your next battery build.
Awesome videos, thanks for sharing your adventures.
