Batteries all sold to @addisonk. The BMS is still available however.

Hi @addisonk, I have 4 100Ah cells also bought from LBSA in 2021 which are no longer being used. I suspect that one of them has failed however, as the voltages on the 3 cells are between 3.1 and 3.2V, however the one is at 2.55V (BMS cut-off voltage). It might have just been due to a bad connection on the battery, but I have no way of charging the one individual cell up again. They had only been cycled approximately 30 times in my DIY setup (no longer being used). I am willing to sell the 3 for R600 each, and you can have the fourth one for free (it might be recoverable if you have something to charge it up/balance with the rest) - are you interested? I am based in Durban. I also have a 4S 12V 120A BMS, if anyone else is interested?

No solar yet, but I am keen to connect panels eventually! Please let me know if you have any luck setting any panels up with it.. Thank you for the link - I am keen to see how you go with changing the fans!

Yes, the fans sound like jet engines just about to take off.. even under no load or charge. I had to put this whole setup in the garage because of the noise. I didn't top balance the cells, but they all came at the exact same voltage (bought them from lithiumbatteriessa.co.za). Where did you get yours from?

@sunset1, seems like we have the same setup? 🙂
