Re: Best Method for Battery Build??? 16s4p Telsa 2170 Cells

It is out of the middle of the Tesla 3 battery pack. The coolant channels are aluminum coated in a plastic like material. It runs the length of the battery every other row. I cut across the channels however cutting thru it damages several cells. It was only possible for me once I dissected the batte...

Re: Best Method for Battery Build??? 16s4p Telsa 2170 Cells

The volt battery performed nicely, it was a modded meanwell that short circuited while charging that ultimately fried the battery. I don't think you can have both factory wiring and keeping it close to bike width. You could possibly maybe get a large section cut out with the original busses but it w...

Re: Best Method for Battery Build??? 16s4p Telsa 2170 Cells

It is just that. A chunk of the whole battery. I suppose you could remove pieces following the pattern the factory had them connected. They are in a intricate pattern so it wouldn't be easy nor practical for most because the amount of cells connected in parallel. The whole battery is dismantled now,...

Re: Best Method for Battery Build??? 16s4p Telsa 2170 Cells

Has there been a determined preferred way to wire together a pack? I know some are against the solder/fuse wire method. Would it be in better interest to invest in a spot welder?

Re: Best Method for Battery Build TESLA 2170

The top center of all cylindrical cells such as the 18650s and these tesla 2170 are positive. The top edge, sides and bottom are negative. That is why they usually wrap them and add the insulator ring. In the close up cell top picture you can see the weld spots for both positive and negative leads. ...

Re: Best Method for Battery Build TESLA 2170

I think you are going to cut that up to alternate more positive or negative or positive or negative 16 times ? How does that block as is help you ? Figured I could do fuse wire like the way it came. Similar to this without flipping the batteries. quote=EbikeAus post_id=1365637 time=1521369971 user_...

Re: Best Method for Battery Build TESLA 2170

Yes, all cells were positioned the same direction across the whole battery. Many (I believe) aluminum buss bars connected all the batteries via fuse wires to the top of each cell. Either to the positive center or negative top edge. 20190906_220503_2.jpg[/attachment [attachment=0]20191112_080749~2.jpg

Re: Best Method for Battery Build TESLA 2170

Milage was less than 3k. Came out of California. Selling groups of individuals cells that would need be configured anyway you want. Can be built in any series or parallel configuration. Most that can be shipped is 60 per box. Not sure on the amp rating as nobody really knows yet. I have seen 3c and ...

Best Method for Battery Build??? 16s4p Telsa 2170 Cells

Previously had a 15s1p chevy volt battery mod in combination with my 9c m3004rc motor. Was really impressed with the match but unfortunately burnt the battery out. Pulled 34mph and got me around everywhere i needed to go. FB_IMG_1574397718602.jpg Just recently got the Tesla Model 3 battery in and ma...

Re: What is your favorite 500W-3000W Direct Drive Hub Motor?

Nine Continent m3004rc motor as a back hub bought from grin at ebike.ca for $148. I have a home built 62.5v 15ah lithium battery. It's my daily driver, hits 35mph fresh off the charger and runs about 20 miles. Not sure the controller specifics as it was a free replacement of a old sinewave controlle...

Re: Mongoose CX450 Controller Upgrade ISSUES!!! KELLY KDS362

Figured out the issue I think. Opened up the controller and immediately got a whiff of burnt electronics. Upon further examination I found 2 of the 11 mosfets broken in half, and 3 others cracked. Guess thats what I get for buying it used of ebay.

Mongoose CX450 Controller Upgrade ISSUES!!! KELLY KDS36200e

Ok, I have an old mongoose CX450 bike. I upgraded the battery from the stock 24v SLA to recycled lithium batteries running 36volts. I burnt the stock controller out last year as well as the controller that replaced it. I recently made 1p9s lithium batteries from a chevy volt module and bought a kell...

Re: Possible battery pack, other equipement?

But that agni motor can only handle about 200ah cont. And 400ah peak. Those cells are overkill and you would only be able to draw 10c cont. 20c max. You wont be using them to their potential but free is free. Might want to set up a few in parallel to get longer range. 20ah wont last but 10-15minutes...

Re: Agni 111rdr

Ok, I thought this motor might be to much for a regular ebike. Just saw the price and thought i wouldn't find this good of a deal again. So I guess i will be shopping for a donor bike shortly. So I am clear voltage is directly related to rpm = speed and amp = torque. This may be a dumb question but ...
