Lithium packs source

[orangeman6]

I keep checking EV battery center, but it still says they’re not able to supply any lithium packs at this time. Does anyone know if they have any sort of timeframe for being able to do so? Or, does anyone know of any other suppliers with similar prices and service? Everything else I’ve found on the net is quite a bit pricier.

My pack was due to be replaced last spring. I even ordered a 48v dpi and 8v battery cables from Scotty. About that same time, I started thinking more about lithium, so I held off on replacing. I’ve still got that stuff just sitting in the garage, but I’d rather go with lithium, if it makes sense.

I also want to go with lithium. The weight reduction and performance seems like a major benefit. But I cannot figure out how to do it. I have researched but just don’t know to much about my system or changing it to lithium system

I don’t either, and that’s why I was slow to pull the trigger on one of the ev packs. I was trying to learn all that I could. There was a stretch, maybe a year ago, that there were posts about it almost daily. EV battery center sadly lost a person that was integral to this part of their operation. I’ve seen some relatively recent posts about guys that sourced parts from different places and were able to put their own packs together. I had no problem learning what I could, but a packaged diy pack, along with a bit of support, was going to be way more in my comfort zone.

If you search lithium on this site, you’ll find many great threads. If you see anything from pingeye, pay close attention. He seems to have put together multiple packs for guys at his golf cub. Also seems like has a bit of e engineering background.

Has anybody tried these people. Some have free shipping from China. The Chinese equivalent of Amazon.

I don’t know, but it doesn’t look familiar. I know that I’ve read that there are definitely different levels of quality, along with lithium type. For me, I was hoping to find a source with a fully integrated solution. Batteries, bms, etc.

Alibaba is the Chinese amazon. My charger did come from AliExpress though. BMS from zeva.com.au

PM PingEye3 and see if he can get you the complete kit from EV.

This would be a nice cell I think, 3.2v 100ah.

I am trying to understand all the issues with building up a pack and control.
Great thread support here on BGW!

It just seems to be still costly at this point at the cell cost level.
I have not researched a lot of cells so I may be in the dark on this.

This is $550 for four cells and would need 16 for 51.2V setup.
So that's $2200 or $137.50 per cell.
Can cells of 100ah be expected to drop soon or are cell prices stable for awhile?
Is the supply limited at this point in the US making it costly and hard to find?

Keep shopping, look for a price of $100 or less per cell for 3.2V 100 A/H LiFePO4 cells. A BMS will cost you a few hundred $ and a charger a bit more.

Is this a good deal?

It's hard to tell. What did it say?
