can you build a 54.4 [48.1v nominal]30ah pack? what would dimensions be?? I domt know the specs of Tesla cells
Same question, with USA shipping. I would need to get a 48 Vdc (with 30~40 Ah) battery pack. Your printed cell holders look fine to me, but I would have to know the number of cells that I would need for my pack(s). I could CAD something up if you want, if I had the dimensions of your cell holders, maybe across five cells.
Hopefully I can figure out a decent BMS and charger set-up. I have some electronics experience, but not much experience with batteries.
Total noob to ebikes here, so please bear with me.
I can build any type of pack. For the dim's of the holders, look at the picture I put up of the triangle pack. you can count the cells and the dims are in mm's. I did measure 5 cells in a pack, and the outside to ouside dim of the CELLS is 96.07mm. The hex holder wall is right about .8mm to 1mm.
I will only ship to the US so if you are in canada, I can ship to a PO box or similar so you can pic up in the US and take across the border.
on the pack size, that is a generic size. I can do pretty much anything, so you need to give me your limiting dims, and I work around that. I have been working with a guy on a triangle pack, and there was a TON of back and forth. after about 30 msgs we are both happy and moving forward on the pack. I am sure it gets a bit annoying me always asking what you want, but I WANT to make sure what I am spending my time making, is what the other person on the other end of the computer is EXPECTING.
If you want to put on your own balance leads, and main leads you can take that price off. I have bought a Bluetooth and UART BMS and I was very happy with one, I was less happy with another (both were similar, one was a 4S (not happy) and a 7S (very happy). I was only using them as balancer.
If you have any questions let me know.
