SUPER LifePo4 Deal (280AH LFP)
« on: February 21, 2020, 05:30:23 AM »
Hi folks,

I am in the process of converting to Lifepo4 Battery Packs from my current Rolls Surette FLA Bank.
The FLA bank is 856AH @ 20hrs for 428AH/10Kwh @ 24VDC useable which turned out to be a tad short for my needs.
I have already installed 24V/350AH of LFP and am now adding another 560AH for a total of 910AH.

During the process of investigation I came across this company which has an outstanding deal on cells.  Other members within my group have already purchased, received & tested the cells and they are indeed Grade-A and meet specs right on the button.  The sales Representative Amy Wan is outstanding in her commitment to communications and dealing with us customer's, she even goes out of her way to message after hours to connect.   They will also send you photo's with your Name Card on the cells while being tested & packed as well as a video during the cell voltage tests.

4 cells = 12V, 8 cells for 24V, 16 Cells for 48V.

I HAVE NO CONNECTION TO THE COMPANY, I am just a customer and want to share a great find for everyone's benefit.

Company Name is Xuba Electronics.


BMS Suggestions:
I can recommend Chargery BMS which are a good solid BMS system with built in balancer.  They are programable, have a remote for monitoring, programming etc and can have the firmware flash updated as well.   Support is very good and the BMS's have a flexible configurations allowing you to configure as Common Port or Separate Port modes for charging & discharging.  * Chargery also has Cold Temp Disconnect  *
Chargery BMS Link:   Can be purchased directly through Chargery but also through the next link.

There are other BMS's with various features & functions up to and including BlueTooth, WIfi etc...

I didn't take a very close look at all this yet. The one thing I noticed is that it is only 1C output where a lot of lithium have a much higher discharge capacity.  Guess it doesn't matter if the 1C suits the needs.
