Building my new LiFePO4 pack from Prismatic cells

If you’re not in a hurry, check out Gobel power for cells. They have surplus grade A cells at reasonable prices. Delivery takes about 60 days from what I’m told.

I've used gobel power on aliexpress too. Those cells are in my ryobi mower now. They were worth the money but I question if they were truly "grade A" since I never got the paperwork to state so.

60 days I'd look for a vendor with a US stock. My last AliExpress spare cells came from Poland ( here to Germany ) within 7 days.

doubt they can ship lithium via air, so a slow boat from china is what they got

I picked this BMS.....
https://www.docanpower.com/index.php...product_id=557

300A with Bluetooth up to 21 cells.
Any issues using this BMS?

Looks like I'll be getting EVE cells from Docan, Texas warehouse

What is the balance current on that JBD ?
The often referred JK does 2A

My last order of cells from aliexpress took 60 days or so.. they do ship the slowest cheapest way which saves money buy not good if your impatient.. it was hard waiting that long. But I saved like $400 so..

I have both this jbd in my riding mower and the jk in my cart.. jk is 2 a active balance meaning the voltage excess is taken from highest cells and transferred to lowest. The jbd is like 800ma I think and it's passive meaning the cells with the high voltage get that voltage burned off or wasted by resistors to bring the voltage down closer to the others.

Augie, nice to hear from you again... ( Pat is still missing!? ) the passive balancer of the JBD is pretty worthless in my experience, I've attached an Neey active balancer for that reason. Best solution is a JK, which comes next.

I tried calling DocanPower about their batteries

Be aware that every phone number listed on their website and through Google comes back as "Your Call Cannot Be Completed As Dialed"

They either have closed up shop or do not want calls.
