Why would there be hot interconnections? Sorry but I am still relatively new to this.

The current that is able to flow is resisted by less copper strips though, no?

“LiitoKala 3.2v 50Ah lifepo4 cells 3.2v lifepo4 lithium batteries for electric bike battery pack solar energy system” is how you can find them. These are from AliExpress. No, the tabs came laser welded onto the battery. I feel as if the method I provided could work if I simply stacked enough...

https://endless-sphere.com/forums/viewtopic.php?f=10&t=112357 I made a few posts on a build thread a few weeks ago. I wasn’t aware we had a battery tech. thread, my apologies for polluting the pages up! Anyways, I’ve run into some trouble while connecting 24 LifePo4 cells in series. They...

I created a new post yet I guess I didn’t need to. The terminals can have nickel spot welded to them is all I know.

Also, stupid question. Do I need the copper to make contact with the terminals rather than through the nickel? If it must go through the nickel to reach the copper (which is the less resistive path) ITLL STILL GO THROUGH THE NICKEL? Assuming no copper is making any contact. Therefore, the nickel...

I have, however I feel it doesn’t apply since I’m dealing with two terminals and a small area of conduction. I need thicker copper to handle the amperage rather than 0.15mm of copper. I could be mistaken. If I do need thicker copper then I need a way to mount it and I’m still contemplating...

Hey all, I recently made a post about connecting my 24 LifePo4 cells in series to create a 72v, 100a cont. pack. Here’s the old post for more detail: https://endless-sphere.com/forums/viewtopic.php?f=10&t=112103. I apologize if linking the post is breaking some rules or something. The terminals...

Hello all - I’m having trouble connecting my 24 LifePo4 cells in Series. These are 3.2v, 50ah. Now, the terminals do not have screws/holes for me to connect nickel or copper plates for connecting purposes. Therefore I must solder or spot weld these (assuming no other options). Since my...

What a crazy story, I'm glad I am asking these questions.. I am afraid the 100 will make me look like a clown on a bike :lol: -- I have some ideas to stretch the riding position at least. I love the DT1 as well, I chose this enduro pretty much randomly off of craigslist but have fallen in...

I mention LifePo4s because that seems to be the go to battery for ev's. No? I understand they have a moderate discharge rate compared to other lithium batteries. However, I am aware that they have a large cycle life and that is why I am primarily interested. If, however, my controller requires...

Hi all, I am fairly new to this forum (and type of project) but see that it is quite helpful when it comes to these e-builds. I'll touch on a little bit about my project and then ask some questions that I hope some of you can help me with or guide me towards the proper solution. Background: So...
