Brushless Posted June 28, 2023 Share Posted June 28, 2023 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? Quote Link to comment Share on other sites More sharing options...
Brushless Posted June 28, 2023 Author Share Posted June 28, 2023 I'm not exactly sure, they are exactly the same type of cell but the colour of the shrinkwrap differs so maybe different batches. Quote Link to comment Share on other sites More sharing options...

My bank is still charging up and then a balance before I put it into service.

Scorp007 Posted July 16, 2023 Share Posted July 16, 2023 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. zsde and Brushless 1 1 Quote Link to comment Share on other sites More sharing options...
Brushless Posted July 17, 2023 Author Share Posted July 17, 2023 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. Quote Link to comment Share on other sites More sharing options...

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.
