Hi All, I have upgraded my battery so am selling some of my carefully looked-after pre-owned lithium cells. They're LiFePO4, 3.2V, 100Ah, 320Wh prismatic cells manufactured in 2021 and have done less than 300 cycles, always protected by a BMS. Note: Typical life cycles on these cells exceed 4000 so there's plenty good life in them yet. See screenshot of them perfectly top-balanced at 3.624V, with a 4mV cell voltage difference. Note also that they deliver 98% of stated capacity. Come with busbars and cell holders.

Prices:
1.28kWh, 4 cells, 12.8v, 100Ah - R3200

2.56kWh, 8 cells, 25.6V, 100Ah - R6400
5.12kWh, 16 cells, 51.2V, 100Ah, - R12800

 

Accept Cash, GeoPay, Yoko or instant cleared EFT only.
Collect in Randburg, no deliveries. Courier at own cost.

Call or WhatsApp: Graham on 0834006123 or PM here.

Grab some power before they're all gone and loadshedding comes back!

Are all these cells the same age and same cycles?

So after 2 weeks of cycling my NEW cells I eventually got my JK BMS connected and on line. What a surprise to see cells only differ by 1mV.

A shout out to Andy's channel for the vital info to start the BMS with external power of 5V above the battery voltage when using on less than 14 cells. 8 in my case.

That is a good variance for the cells but rather check the cell imbalance at higher voltages, ie over 3.5v per cell. Any imbalance will show more clearly at either high or low voltages.

Thanks. I did see higher  imbalances (14mV) while charging  after I put on the BMS. I just mentioned it as there were no balancing during the 2 weeks of actual using them. The pic was taken the moment I switched on the BMS and no source/load while doing a setup of the BMS.

Hi all, I've upgraded another battery so have these LiFePO4 cells for sale again. They are used cells but are well balanced and producing 98% of their rated capacity. 

16 x 3.2v, 105Ah, 51.2v, 5.3kWh - R12000 (or 2 x 24v - R6000 each) 

16 x 3.2v, 100Ah, 51.2v, 5.1kWh - R12000 (or 2 x 24v - R6000 each) 

Can split into 4 x 12v 100Ah packs for camping or 4x4
